The ketogenic diet is one of the most effective diets around for burning belly flab fast, but what are the absolute BEST ketogenic foods for the fastest fatloss? Here are the top 14 ketogenic foods for accelerated fat-burning.
In case you haven’t heard, there’s a (not-so-new) diet craze that’s winning the world over. It’s called the Ketogenic Diet.
By: Tim Ernst – Founder of Intermittent Keto Fasting
While it’s recently experienced renewed interest and an explosive rebirth, it’s been in practice for nearly a century. Scratch that, it’s likely been in practice for thousands of years.
But what is the ketogenic diet? What can it do for you? How does it work? What foods can—and can’t—you eat? Does it live up to the hype? Are there any disadvantages? Should you jump on the bandwagon?
What is the Ketogenic Diet?
The ketogenic diet is a very-low-carbohydrate, high-fat, adequate-protein dietary approach.
In fact, it is more commonly referred to as a very-low-carbohydrate ketogenic diet (VLCKD).
We’ll get into more specifics in a moment, but first a brief lesson in history.
By: Shawn Wells R.D.
The History of the Ketogenic Diet
As far back as 500BC, there is documentation of using fasting and diets that mimic fasting to treat epilepsy.
Heck, there’s even reference to it in the New Testament of the Bible.
For instance, in the book of Mark, there’s a story of Jesus curing an epileptic boy. So, what does fasting and epilepsy have to do with the ketogenic diet?
Back in the early 1900s, a pair of French doctors were the first to document their use of fasting to treat children and adults with epilepsy.
They found that the starvation diet resulted in significant improvements—fewer seizures and those that they did experience were less severe.
In the 1920s in the United States, Dr. Hugh Conklin experienced a great deal of success using starvation as a treatment for epilepsy.
Another pioneer ahead of his time was Bernarr Macfadden, who was a fitness guru and referred to by some as “the Father of Physical Culture.”
Macfadden authored a magazine, Physical Culture, where he suggested that any illness could be prevented or cured with a combination of exercise and diet, with an emphasis on periodic fasting.
His rationale was that because so much of the body’s energy goes into digesting food, if there’s none to digest, more energy could be applied to recovering health.

Dr. Conklin and Macfadden ended up teaming up, and it was their work that drew the attention of endocrinologist Dr. Rawle Geyelin, who used their methods to treat epilepsy.
Dr. Geyelin also noticed how fasting seemed to improve cognitive function.
Harvard Drs. Stanley Cobb and W. G. Lennox attended one of Dr. Geyelin’s presentations, and their interest was piqued by his success.
Dr. Cobb and Lennox wanted to dig deeper and study what was happening. Why was starvation so effective?
They found that improvement usually took place after about 2 – 3 days of starvation.
Even more importantly, they found that, around this time, there was a shift in the body’s metabolism.
More specifically, in the absence of carbs, the body was forced to shift into a full-fledged fat-burning mode.
Of course, there are problems with starvation. Compliance is obviously an issue. Oh yeah, then there’s the finality of death.
Dr. Russell Wilder, at the Mayo Clinic, recognized that there was another way to get the body to “shift” into this state that mimicked fasting without starvation.
Dr. Wilder created a “ketone-producing diet” as a treatment for epilepsy in 1924, and he proposed that it would be as effective as fasting. Not only that, it could be maintained for a much longer period of time.
Dr. Wilder referred to this new diet as the “ketogenic diet.”

Dr. Wilder’s ketogenic diet was pretty straightforward. Patients consumed about 0.45 grams of protein per pound of body weight, and they were restricted to 10 – 15 GRAMS of carbohydrate per day.
The rest of their food intake was from fat.
Despite its effectiveness, the ketogenic diet was gradually used less and less for this application.
If you’ve guessed that “big pharma” played a role, you are right.
However, around 2000, things changed substantially thanks to NBC’s Dateline, which highlighted the ketogenic diet on a national level.
The TV program shared the true story of 2-year-old Charlie Abraham’s, who had difficult to-control epilepsy (despite using multiple medications).
As a last resort, his parents turned to the ketogenic diet. It worked. Charlie became seizure- and drug-free within a month, and he hasn’t had a seizure since.
In 1994, his parents founded the Charlie Foundation, which is recognized as a global leader in promoting ketogenic therapies for people with epilepsy, other neurological disorders, select cancers, and various other health conditions.
For you movie buffs out there, Charlie’s father Jim produced and directed the movie…”First Do No Harm” starring multiple award-winning actress Meryl Streep.
The story, which is loosely based on the Abraham’s experiences with Charlie, is about a boy whose severe epilepsy, which is unresponsive to medications, is controlled by the ketogenic diet.
While that marked its resurgence on several levels, the ketogenic diet started gaining popularity as a weight-loss diet in the 1970s when Dr. Robert Atkins published a book titled Dr. Atkins’ Diet Revolution: The High-Calorie Way to Stay Thin Forever.
And while the rest of this article will focus on the application of the ketogenic diet in weight management and overall health, it’s important to highlight that there’s more and more scientific research evidence mounting suggesting the therapeutic potential of the ketogenic diet for:
- Traumatic Brain Injury
- Type 2 Diabetes (T2D)
- Metabolic Syndrome
- Polycystic Ovary Syndrome
Is it Effective for Weight Loss?
There’s a never-ending debate about what’s the “best” diet for weight loss.
Purely from a weight-loss perspective, there is more than one way to skin a cat.
That being said, there’s no shortage of evidence clearly and convincingly showing that the ketogenic diet is a highly effective tool for weight management.
In a randomized controlled trial published in the journal Endocrine, researchers from Spain found that obese participants following a ketogenic diet (VLCKD) for just two months lost nearly 30 pounds.
During the same time, participants following a standard low-calorie diet lost just 10 ½ pounds.
After 12 months, 88% of the folks in the VLCKD group had lost more than 10% of their initial starting weight and nearly 3 times more weight than the low-calorie group.
Several well-controlled studies have shown similarly impressive results with the ketogenic diet.
In one study published in The American Journal of Clinical Nutrition, researchers found that obese men following the ketogenic diet for 4 weeks lost nearly 14 pounds—46% better results than a group eating a “moderate” carbohydrate diet.
Even more fascinating was that the men lost the weight without having to consciously restrict calories!
Meanwhile, additional randomized controlled trials have shown that participants sticking to the ketogenic diet lose 2 – 3 times more weight than a typical low-fat or heart healthy diet.
Perhaps most striking are the results from two separate systematic reviews, which arguably represent the most critical assessment on the topic.
In a meta-analysis of randomized controlled trials published in the British Journal of Nutrition, Brazilian researchers concluded, “Individuals assigned to a VLCKD achieve a greater weight loss than those assigned to a [conventional low-fat diet] in the long-term; hence, a VLCKD may be an alternative tool against obesity.”
In a meta-analysis published in The Lancet, an esteemed panel of researchers from Harvard Medical School concluded, “In weight loss trials, higher-fat weight loss interventions led to significantly greater weight loss than low-fat interventions.”
How Does It Work?
Clearly, when it comes to weight loss, the ketogenic diet works very effectively.
So, how exactly does it work? Great question!
The answer is that it depends on who you ask. I know, how boring is that answer?
According to Italian researcher Dr. Antonio Paoli, who has published several studies on the ketogenic diet, the most likely explanation for improved weight loss is appetite suppression.
Indeed, a recent review study published in the journal Obesity Reviews found that the ketogenic diet suppresses appetite, reduces hunger, increases satiety (feelings of fullness and satisfaction).
Additional studies have shown that the ketogenic diet reduces levels of the “hunger hormone” ghrelin and increases levels of satiety hormones, such as CCK.
It is thought that ketone bodies have direct appetite-suppressant properties.
This explanation is very important; in fact, it’s arguably more important than a metabolic advantage. How many times have you dieted to lose fat only to lose the battle with uncontrollable hunger and cravings?
If you’re like most people, probably more often than not.
After all, under normal circumstances, when you follow a reduced-calorie diet and lose weight, your body fights back ferociously by increasing hunger hormones and reducing satiety hormones.
In other words, your body is programmed to combat your best efforts by pushing you to overeat, especially high-calorie, tasty foods (i.e., “junk” foods).
Contrast that with the ketogenic diet, which has been shown to prevent an increase in appetite despite weight loss.
In fact, a recent study published in the International Journal of Obesity showed that, like any diet, the early stages of the ketogenic diet can lead to increased hunger.
However, after just a couple weeks, hunger is suppressed and appetite is regulated—despite continued weight loss.
As you might have guessed, this has tremendous implications for long-term weight loss and weight maintenance.
What Other Health Benefits are Associated with the Ketogenic Diet?
Looking for a surefire way to improve glycemic control and metabolic function? Cut carbs.
Given the very nature of the ketogenic diet, it should come as no surprise it is a highly effective dietary strategy for folks who are carbohydrate intolerant.
In fact, studies have shown that when carbohydrate intolerant individuals follow the ketogenic diet, the “results have been nothing short of remarkable,” including dramatic improvements in glycemic control, insulin sensitivity, and body weight.
For what it’s worth, exercise, particularly resistance training, is also remarkably effective at improving carbohydrate metabolism and overall metabolic health.
So, why not do them both? Studies combining weight lifting with the ketogenic diet result in impressive changes in body composition and strength.
Considering that the body is equipped to create ketones just so that it can fuel the brain, you may be wondering if the brain is actually designed and intended to run on this clean, efficient, alternative source of energy.
In other words, are ketones the “preferred” source of fuel for the brain?
That’s an interesting question, and there are certainly folks who believe that’s the case.
Experimentally, many ketogenic dieters report better focus, less brain fog, and fewer energy crashes.
And some studies have shown that the ketogenic diet improves cognitive performance.
On top of that, research is accumulating showing that the ketogenic diet may be neuroprotective, helping preserve cognitive function.
The ketogenic diet is very high in fat, so it must be “bad” for your heart, right? WRONG.
For starters, if you’re still stuck in the mindset that fat is bad, particularly saturated fat, give me your hand.
I’m going to pull you out of that deep, archaic rut. It’s now well established and widely accepted that saturated fat is not associated with heart-related issues and other adverse health outcomes.
If you’re wondering what is to blame, ironically, it’s the exact foods that we’ve been told to replace saturated fats with:
- Refined vegetable oils high in omega-6 fatty acids (e.g., replace butter with margarine); and
- Refined carbohydrates and added sugars (e.g., low-fat processed foods).
Anywho, the ketogenic diet may improve heart health a number of ways.
Like we’ve already mentioned, it’s been well-established to decrease body fat and improve glycemic control and insulin sensitivity, all factors that influence cardiovascular health.
On top of that, multiple studies have shown that VLCKD can help maintain blood lipids (e.g., cholesterol, triglycerides) and blood pressure in a healthy range.
In fact, comprehensive review studies show that the ketogenic diet has a more favorable impact on markers of cardiovascular health than the more commonly recommended low-fat diet.
If you’re shaking your head in disbelief, I am too. But maybe for a different reason.
It is shocking, befuddling, and disappointing that the misguidance to eat low-fat and replace saturated fats with vegetable oils is still so pervasive.
With profound heart and brain health benefits, it’s not a surprise that the ketogenic diet helps support healthy aging. After all, these are easily two of your most precious organs.
You can’t age healthfully and gracefully without them both in tip-top shape.
Beyond those benefits, the ketogenic diet has some very unique anti-aging properties that are often overshadowed by its weight-loss advantages.
Even though you’ll be eating on a ketogenic diet, you may recall that it, for all intents and purposes, simulates fasting.
Fasting and caloric restriction are regarded as the most effective ways to slow down the aging process.
Like fasting and caloric restriction, the ketogenic diet up-regulates important cellular processes, promoting stress resistance and autophagy, which essentially means “cellular cleaning” or “cellular detoxing.” Pretty cool stuff!
While it can get a little complex, the ketogenic diet also acts similarly to caloric restriction and fasting by up-regulating key coactivators, enzymes, and genes (such as PGC1α, AMPK, and SIRT-1).22 You don’t have remember the alphabet soup.
What’s important is that these compounds have powerful anti-aging properties.
For instance, they can help increase the number of mitochondria (through a process known as mitochondrial biogenesis), which are known as the “powerhouses” of cells because they create energy.
These compounds are also known as “exercise mimetics.”
In other words, activating them through the ketogenic diet may offer some of the same beneficial effects as endurance exercise.
One more thing to mention again is that ketones are a very clean, efficient source of energy.
By that, I mean that your body can generate more cellular energy from ketones than glucose or fat.
That also means that when your body metabolizes ketones, it generates much lower levels of oxidative stress.
This is important because excessive levels of oxidative stress are associated with cellular aging and the aging of virtually every tissue in your body, including the brain, heart, joints, and more.
Recently, the ketogenic diet has strongly re-emerged as a tool to enhance sports performance many thanks to recent research, enthusiastic claims, testimonials, and perhaps most influential, social media.
I say “re-emerged” because, for years, scientists have tried, largely unsuccessfully, to prove that “fat loading” protocols like the ketogenic diet could enhance endurance performance.
It makes sense that a high-fat ketogenic diet would help fuel performance in long duration sports like running and cycling.
After all, well-trained athletes can burn an enormous amount of fat during these types of exercise, and a metabolic adaptation to the ketogenic diet is shifting the body into burning fat and ketones exclusively. However, the research is conflicting.
Some studies have shown a clear performance benefit while others have shown no beneficial effect.
Overall, it seems like the ketogenic diet doesn’t necessarily impair performance, but it also doesn’t seem to consistently improve endurance performance.
There are several reasons why this may be the case, including poor study design.
For example, it may take some athletes longer to adapt than others.
Because of the lack of carbohydrate, it is often speculated that the ketogenic diet results in poor performance in high-intensity activities.
While that may be the case in certain instances, recent studies have shown that combining the ketogenic diet with weight lifting results in comparable (and in some cases, better) improvements in strength, power, and body composition as the typical Western diet.
So, the ketogenic diet may lead to improvements in sports performance and adaptations to exercise training.
Like any dietary approach, if you choose to give the ketogenic diet a shot, make sure you’re consistent and stick with it!
What Does the Ketogenic Diet Look Like?
Remember, the ketogenic diet is a very-low-carbohydrate, high-fat, adequate-protein dietary approach. Traditionally, ketogenic diets are:
- Very high in fat (~70 – 80% of calories)
- Very low in carbohydrate (~5% of calories or ≤ 30 grams per day)
- Adequate in protein (~ 15 – 20% of calories)
What does that translate to? Here’s what the ketogenic diet would look like on a traditional 2,000-calorie diet:
- 165 grams of fat (75% of calories)
- < 30 grams of carbohydrate (5% of calories)
- 100 grams of protein (20% of calories)
Now, if math isn’t your thing or you simply want more personalized results, then your best bet is to head over to this link here and use the nifty Keto Calculator, which provides you a complete breakdown of fats, protein, and carbs based on your sex, age, weight, height, activity level, and goal.
Plus the keto calculator will break down 3 different caloric deficits:
- Small caloric deficit of 10%
- Moderate caloric deficit of 20%
- Large caloric deficit of 30%
For instance, according to the Keto Calculator, a 6-foot, 200-pound, 40-year-old male who’s moderately active and is looking to drop weight would eat:
- 2,308 calories
- 183g of fat
- 134g of protein
- 30g of carbs
Meanwhile, a 5-foot, 6-inch, 160-pound, 50-year-old female who’s lightly active and wants to lose weight would eat:
- 1,208 calories
- 84g of fat
- 83g of protein
- 30g of carbs
There are many factors that go into determining what the “best” caloric intake is for an individual, such as goals, age, body composition, weight, activity level, and more.
Even the most reliable and scientifically-validating methods have a margin of error.
In other words, any calculator that you use is simply meant to be a guide.
At the end of the day, week, and month, just ask yourself a simple question: “How’s that working for you?”
One final word on caloric intake. While daily calorie restriction is most common for weight loss, all that matters is that, on average, you’re eating fewer calories than you burn.
If you’d rather eat a little more some days and a little less on others, that’s fine and usually equally effective.
In fact, some take this to a bit more of an extreme through some sort of intermittent fasting. For example, you might eat 25% of your daily target one day and 125% the next.
Research has shown that this pattern of eating—called alternate-day fasting—is just as effective for weight loss and improving health as daily calorie restriction.
What types of foods can you eat on a ketogenic diet?
Like any diet, the ketogenic diet is not about a specific food; it’s about your entire body of work.
In other words, rather than a single food or meal, it’s important that you consistently meet your goals for fat, protein, and carb intake in order to get into ketosis and reap the potential benefits.
Given the constraints of keto, I’ll give you two guesses as to which types of foods you’ll find in the following list. If you guessed fat and more fat, then you’d be right on point.
If you guessed carbs and more carbs, then it’s obvious that I’m a terrible writer.
All kidding aside, fat-dense foods provide the foundation of the ketogenic diet.
Protein rich foods are also a staple of keto; however, it’s important to remember that the ketogenic diet is not a high-protein diet. In fact, too much protein can keep you from getting into or staying in ketosis.
Finally, it’s kind of a misnomer to say that there are “ketogenic foods.”
While there are some foods that lend themselves very well to the ketogenic diet (due to their fat content), there are very few foods that directly contribute to a ketogenic state.
Having said all that, it’s time to go keto!
1. Coconut Oil
If there was one ketogenic food, it would be coconut.
While coconut oil is made up mostly of saturated fats (over 90%), as much as 70% of them are a special type of fat called medium chain triglycerides (MCTs).
You see, unlike long chain fatty acids (LCFAs), which are the more common fats found in foods, MCTs are easily burned for energy and are far less likely to be stored as fat.
MCTs are considered “functional” fats, and they have been shown to lower body weight, improve markers of metabolic health, reduce belly fat, and improve insulin sensitivity.
In other words, all fats are not created equally, and coconut oil is a very rich source of this unique, health-promoting saturated fat.
What’s particularly interesting about MCTs is that they are easily absorbed and metabolized by the liver, where they are readily converted to ketone bodies.
Now you can see how coconut oil may actually be a ketogenic food.
MCTs have been shown to boost metabolism, and they have also been shown to suppress appetite, an effect that’s likely due to their conversion to ketones.
Not surprisingly, coconut oil and MCTs have been shown to promote weight loss.
In one study, a group of Brazilian researchers found that women who consumed two tablespoons of coconut oil per day for 12 weeks while following a reduced-calorie diet and including daily exercise lost significantly more belly fat compared to the placebo group (i.e., diet and exercise alone).
You probably know that you SHOULD be using coconut oil daily for it’s many health benefits (burn fat, boost metabolism, protect your brain, stabilize blood sugar…and that’s just a few!) but you probably don’t have any real idea how to add it to your diet in a delicious way. => Here are 10 ways to add it to your diet.
In another study, researchers from Malaysia found that men who added 2 tablespoons of coconut oil to their normal diets for 4 weeks significantly reduced belly fat.
Meanwhile, several trials have shown that supplementing the diet with MCTs (like those found in coconut oil) leads to greater weight loss and reductions in belly fat than other fats (e.g., olive oil, soybean oil, canola oil, and corn oil).
This is likely due to the beneficial effects of MCTs on metabolic rate, fat burning, and appetite.
With right around 80% of calories from fat, avocados are another near-perfect food for ketogenic dieters. While one-half an avocado contains about 8 grams of carbs, nearly all of them (6 grams) are fiber, which are indigestible.
That brings up an important point when it comes to the ketogenic diet. Generally speaking, most keto resources suggest that you count “net” or “usable” carbs toward your total daily allotment.
In other words, indigestible carbs (such as insoluble fiber) don’t count. So, when you’re counting carbs, make sure you subtract indigestible carbs from the total carb count.
EDITORS NOTE: Avocados could just be one of the most overlooked and underrated superfoods on the planet. Even though they are often considered a vegetable or super-food, avocado is actually categorized as a fruit.
This little wrinkly and unappealing food, is loaded with health benefits that you simply can’t afford to miss out on.
=> Here are 7 recipes that you can make using this super-food, avocados
In this example, one-half an avocado contains 8 grams of total carbs and 6 grams of dietary fiber.
So, one-half an avocado contains just 2 grams of net carbs.
Avocados are also very nutrient-dense containing upwards of 20 essential nutrients, including vitamin K, folate, vitamin B6, vitamin C, vitamin E, pantothenic acid, riboflavin, and niacin.
Avocados are a great source of potassium, which is a very important mineral to consume on the ketogenic diet.
In fact, active people should take in about 2 – 3 grams of potassium per day.31 One-half an avocado gets you almost 25% of the way there, providing just under 500mg.
3. Olive Oil
As a pure source of fat, olive oil is another staple of the ketogenic diet.
But olive oil doesn’t provide just any type of fat. It’s bursting with heart-healthy monounsaturated fats and antioxidants.
For instance, olive oil contains the polyphenol oleocanthal, which has been shown to promote a healthy inflammatory response.
Olive oil is perhaps best known as a staple of the Mediterranean diet, which has been shown to be an effective tool for promoting heart health, improving carbohydrate management, maintaining healthy blood pressure, improved cognitive function, and promoting weight management.
While it may come as somewhat of a surprise, Mediterranean-style diets typically provide up to 37 – 40% of total calorie intake from fat—up to 50% of which comes from monounsaturated fats (predominantly extra virgin olive oil).
In an interesting study, researchers tested a “Mediterranean style” ketogenic diet (MED-KETO), which stuck to the high-fat, very-low-carbohydrate nature of keto while maintaining some advantages of the Mediterranean diet, such as the liberal use of olive oil and some green vegetables.
After 6 weeks, the MED-KETO diet led to significant weight loss, improvements in markers of heart health, and reduced weight circumference.
Olive oil is a great choice as a base for homemade salad dressings, drizzling on green vegetables, low-heat cooking, and for homemade mayonnaise. Speaking of which…
Mayo, which is essentially pure fat, is another food that is well-suited for the ketogenic diet.
This often comes as a relief to many. After all, mayo is America’s favorite condiment.
Believe it or not, according to a recent in-depth analysis, mayonnaise sales more than double that of ketchup ($2 billion versus $800 million).
That said, nearly all store-bought mayo, which is made with soybean oil, is garbage.
This is a problem because cheap, inferior refined vegetable oils, such as soybean oil, are packed with omega-6 fats.
Over-consumption of omega-6 fats promotes inflammation, particularly when they are consumed in excess of omega-3 fats, which are considered to have an anti-inflammatory effect.
With that in mind, you have two better options when it comes to mayo.
One, make your own at home using olive oil or avocado oil.
In its simplest form, mayonnaise is a combination of oil, egg yolk (an emulsifying agent), and either vinegar or lemon juice.
Your second option is to look for mayo at the store that is made only with a healthy oil, such as olive or avocado oil—no soybean, canola, or other junk oil.
Our favorite is, hands down, Primal Kitchen Mayo, which is made with avocado oil and eggs from pasture-raised hens. They even have a Chipotle-flavored mayo. Yum!
5. Nuts and Seeds
Nuts and seeds are high-fat and (in most cases) low in carbs, making them great foods for the ketogenic diet.
In general, nuts and seeds are rich in monounsaturated fats, essential fats, magnesium, zinc, folate, vitamin E, and other important micronutrients.
Here’s a complete list of nuts and seeds, including calories and net carbs from Ketogenic Diet Resource:]
As you can see, you may want to be careful with certain nuts, such as chestnuts, cashews, and pistachios, which are higher in net carbs.
Studies show that folks who regularly eat nuts and seeds have lower body weights.
And despite being calorie-dense, research shows that nut consumption doesn’t lead to weight gain; in fact, most studies show that they lead to weight loss.
What you may not know is that the body does not efficiently absorb all the fat and calories from nuts and seeds.
Instead, studies have shown that the body excretes up to 18% of the calories from nuts.
Eating nuts and seeds increases the release of important appetite-suppressing hormones, and believe it or not, the simple action of crunching and chewing on nuts and seeds can send signals of fullness to your body.
6. Butter, Ghee, Heavy Cream, and Sour Cream
Butter, ghee, and cream are all high in fat and low in carbs, making them keto-friendly.
What about the saturated fat? What about it?
Remember what we mentioned above: It’s now well-established and widely accepted that saturated fat is not associated with heart-related issues and other adverse health outcomes.
What’s even more interesting is that more and more studies are showing that dairy, especially full-fat dairy, is related to less belly fat and better markers of cardio-metabolic health, including blood pressure, cholesterol, triglycerides, and glycemic control.
Not only that, researchers believe that these better health outcomes may actually be brought on, at least in part, by dairy saturated fats.
Shocking, I know. When you’re ready, go ahead and pick your jaw up off the floor.
Add that cream to your coffee. Add some butter to your veggies. But when you do, just make sure that you choose butter and cream from organic, pasture-raised cows.
Compared to conventional milk, research shows that organic milk contains significantly more omega-3 fats (over 50% more) and over 40% more conjugated linoleic acid (CLA).
CLA has been shown to reduce body fat (including belly fat), boost immunity, and promote a healthy inflammatory response.
Like coconut oil, dairy fat (which you’ll be getting plenty of from these foods) is a natural source of MCTs.
Remember, MCTs are quickly burned off as energy, and they’re highly unlikely to be stored as fat.
Even more, the body can readily convert MCTs to ketone bodies in the liver, making butter and cream even more attractive foods for a ketogenic lifestyle.
Lastly, butter is the best dietary source of butyric acid, also referred to as butyrate, which has numerous health benefits.
For instance, butyrate (which is also produced when healthy gut bacteria ferment dietary fibers) serves as a major source of fuel for the immune cells in the gut.
Also, butyrate stimulates the body to release key appetitesuppressing hormones, and butyrate may even help protect the brain.
Simply put, butter is back, baby!
7. Full-Fat Cheese, Greek Yogurt, and Cottage Cheese
Basically, everything that was mentioned above applies to full-fat cheese, full-fat Greek yogurt, and full-fat cottage cheese. Notice the emphasis on “full-fat.”
Since you’re going to need to be eating a lot of fat, you’ll not want to skimp by going with low-fat or skim dairy products.
And why would you want to? Remember, people who eat more full-fat dairy, such as cheese and yogurt, have been shown to have healthier body weights and carry less belly fat.
Also, when you choose organic, full-fat dairy from pasture-raised cows, you’ll get the additional benefits of healthier fats, such as more omega-3s and CLA.
Then there’s the bonus of MCTs and short-chain fatty acids, like butyrate, that support gut health and immune function.
That being said, be careful with these foods, particularly yogurt and cottage cheese.
While they’re very good sources of protein, remember that the ketogenic diet is not a high-protein diet; it’s a moderate-protein diet, so you don’t want to go overboard.
Also, yogurt and cottage cheese also contain carbs. As we’ve mentioned several times, the number one rule of the keto club is don’t talk about the keto club.
All kidding aside, the number one rule of the ketogenic diet is keep carbs to a bare minimum.
A half cup serving of full-fat Greek yogurt contains about 5 grams of carbs (and 14 grams of protein) while a half-cup serving of full-fat cottage cheese contains about 4 grams of carbs (and 13 grams of protein).
And it should go without saying that you should only choose plain versions of Greek yogurt and cottage cheese. None of the flavored or fruit-on-the-bottom garbage with added sugars.
Eggs have been touted as “nature’s perfect food,” “one of the healthiest foods on the planet,” “nature’s multivitamin,” and most simply, “incredible!”
You can add to that list “one of a ketogenic dieter’s best friends.”
Eggs contain virtually zero carbs, and they contain healthy fats, and they are a good source of high-quality protein.
Eggs are also packed with a variety of vitamins and minerals.
They also contain some “bonus” nutrients, including choline, lutein, and zeaxanthin. These nutrients boost brain health and cognitive function, eye health and vision, and heart health.
When it comes to eggs, there seems to be a fair amount of confusion when it comes to topics like cholesterol, traditional versus pasture-raised, shell color, preparation methods, egg whites versus egg yolks, and more.
With that in mind, our goal is to help set the record straight on all topics pertaining to the “incredible edible” egg.
For example, choline has been shown to boost the body’s production of brain-derived neurotrophic factor (BDNF), which is a very important growth factor for the brain and central nervous system, and it plays a key role in cognitive function, mood, and mental health.
Meanwhile, lutein and zeaxanthin have been referred to as “natural sunglasses” due to their ability to shield the eyes from potentially damaging UV rays.
Speaking of which, lutein has also been shown to act as a “natural sunscreen,” protecting the skin in a similar fashion.
When you go shopping for eggs, have you ever asked, “What did the chickens eat?”
You should. After all, the ol’ saying, “you are what you eat,” applies to animals too.
Just like dairy, it’s best to choose eggs from pasture-raised hens, which have been shown to have 2 ½ times more omega-3 fats and less than half the ratio of omega-6 to omega-3 fats as conventional eggs.
You probably saw this one coming from a mile away.
Bacon is a good fit for the ketogenic lifestyle because it is moderate in both fat and protein.
There are a couple things to watch for when it comes to choosing bacon, so you’ll want to read the nutrition labels carefully. For instance, store-bought bacon is often cured with sugar.
It’s not necessarily a lot of sugar, but since you’ll be watching your carbs very closely, you’ll want to avoid unnecessary, added sources such as this.
Go ahead, have bacon with your eggs. Put a couple slices of bacon on a burger with cheese.
Just don’t go hog wild—cheesy pun intended…and there’s another one.
There are better sources of fat, and you’ll want to make sure that you balance your fats overall, getting a good mix of saturated, monounsaturated, and polyunsaturated fats.
You’ll be able to do that by choosing a variety of foods from our list.
10. Cold-water Fatty Fish
Cold-water fatty fish are the best dietary sources of the all-important omega-3 fatty acids DHA and EPA, which are well-known for supporting:
- Heart health
- Brain health, cognitive function, and mood
- Eye health and vision
- Skin health
- Immune function
- Metabolic function and body composition
- Promoting a healthy inflammatory response
Recent research has shown that DHA and EPA may also have anti-aging properties.
In fact, diets rich in these omega-3s can protect, and in some cases, lengthen telomeres, which are a key marker of aging (longer is better).
Even more, research shows that supplementation with EPA and DHA increases the activity of telomerase, which is an enzyme that maintains, lengthens, and restores telomeres.
Pretty cool stuff, right?
At a minimum, it’s a good idea to eat fatty fish at least twice a week.
Here are some of our favorite cold-water fatty fish:
- Oysters are also a great source of DHA and EPA, but believe it or not, they contain carbs.
Beef is a staple of the ketogenic diet.
That said, if you’ve been conditioned to go for leaner cuts of meat, now’s the time to choose fattier cuts.
For instance, instead of lean ground beef or ground sirloin, choose 80/20 or 85/15 ground beef.
Beef is far more than fat and protein, however; it’s packed with a bunch of vitamins and minerals, including vitamins B12 and B6, selenium, zinc, niacin, choline, iron, and riboflavin.
B12 energizes the brain and plays a key role in eliminating potential neurotoxic compounds (homocysteine) that can negatively affect brain health and cognitive function.
Just like eggs and dairy, when you buy meat, it’s a good idea to get the best quality that you can afford. You see, meat from organic pasture-raised animals contains about 50% more omega-3 fatty acids than conventional meat products.
And while all beef contains CLA, grass-fed beef has been shown to contain considerably more.81 That’s a bonus if you’re looking to drop fat and tone up.
Like beef, poultry, especially fattier cuts like thighs and legs, is a staple of the ketogenic diet.
Like beef, eggs, and dairy, it’s a good idea to invest in the highest quality poultry that you can afford.
Just like the nutritional content of eggs is influenced by the hen’s diet, the meat is as well. In other words, pasture-raised chicken is going to have a slightly healthier nutritional profile than chicken from conventional birds.
Like beef, poultry is more than fat and protein. For instance, chicken also provides vitamins B3, B6, and B12, selenium, phosphorus, and pantothenic acid.
Chicken is also a good source of choline. Like B12, choline plays an important role in helping the body neutralize potentially toxic compounds that are linked to poor cognitive function and declining brain health.
Another advantage of poultry is that it’s incredibly diverse, and you’ll find a ton of delicious keto recipes including chicken. Seriously, there are hundreds of them from stuffed chicken to bacon-wrapped chicken to jerk chicken to chicken pot pie and more!
Coffee is low-carb, so it’s a natural fit for the ketogenic diet.
You’ll just want to avoid adding carbs in the form of sugar. However, you can add heavy cream, coconut oil, or even butter if that’s your cup of tea…or coffee. Speaking of tea, that’s keto-approved too.
Despite an undeserved bad reputation in certain circles, coffee is associated with numerous health benefits.
For instance, regular coffee consumption is associated with reduced risk of type 2 diabetes and certain neurodegenerative diseases, such as Alzheimer’s and Parkinson’s.
Coffee consumption is also associated with reduced risk of cardiovascular disease.
Along with coffee comes caffeine, which helps boost metabolism, increase alertness, boost energy levels, improve mental and physical performance, make physically demanding tasks seem easier, and more.
It should go without saying, however, that you need to pay attention to your caffeine tolerance.
Some people are slow caffeine metabolizers, and the downside (e.g., jitters) outweigh the potential benefits.
Berries? We don’t need no stinkin’ berries!
Generally speaking, it’s a good idea to avoid carb-containing foods like fruits, starchy vegetables, grains, and legumes when following the ketogenic diet.
However, once adapted to the ketogenic diet, which may take weeks (and for some folks, months), then many find that they can include small amounts of certain carb-containing foods while still maintaining ketosis.
Berries are well-known for their many potential health benefits.
They’re packed with dark-colored polyphenols that serve as powerful antioxidants that can also help promote a healthy inflammatory response.
Among fruits, they have a relatively low amount of net carbs, so they are typically the first to be introduced.
Here’s a summary of net carbs per 100-gram serving (3 ½ ounces) of some popular berries:
