11 Funny Keto Comments

author avatar Dr. Eric Berg 08/31/2023

We’re going to talk about 11 funny keto comments that I’ve gotten in the past. These are questions, concerns, or misconceptions about the keto diet that are surprisingly common (and, in my opinion, pretty entertaining).

In this article, I will cover 11 funny keto comments and explain the truth behind them:

  1. I can’t do keto because I have type 2 diabetes
  2. All that bacon fat is going to clog my arteries
  3. Keto is a recycled Atkins diet
  4. Keto causes ketoacidosis
  5. High-fat diets will kill you
  6. Our brains run on carbs
  7. Keto will cause your muscles to shrink
  8. Keto is not good for the thyroid
  9. There are no long-term studies that prove that keto is good long-term
  10. Keto gives you bad breath
  11. Keto is not sustainable

Let’s clear the air.


1. I can’t do keto because I have type 2 diabetes

Keto can actually help with type 2 diabetes

That’s exactly why you need to do keto. Even the American Diabetes Association validates and acknowledges that a low-carb diet is actually beneficial for diabetes.

Why? Well, let’s back up here.

Diabetes refers to a group of diseases that affect how your body uses blood sugar or glucose. The underlying cause of diabetes varies by type, but overall you can expect to have excess blood sugar with this condition. This chronic high blood sugar can lead to various health concerns and complications, including:

  • Cardiovascular disease
  • Nerve damage, or neuropathy
  • Kidney damage, or nephropathy
  • Eye damage, or retinopathy
  • Foot damage
  • Skin conditions
  • Hearing impairment
  • Alzheimer’s disease
  • Depression

This is why diabetes is such a serious disease.

With type 2 diabetes, in particular, your cells become resistant to the action of Fat Storing Hormone (the hormone that regulates sugars in your body) and your pancreas is unable to make enough Fat Storing Hormone to overcome this resistance. Instead of moving into your cells where it's needed for energy, sugar builds up in your bloodstream.

Well, the only macronutrient that doesn’t affect blood sugars or trigger Fat Storing Hormone is fat. That’s why the keto diet - which makes you run on fat instead of sugar - can really steady blood sugars and help with many diabetes symptoms.


2. All that bacon fat is going to clog my arteries

The stereotype here is that, on keto, you’re going to be eating a ton of fatty foods like bacon, and that this will cause heart problems.

First of all, bacon isn’t as bad as people think. When you’re frying bacon, you’re frying off the majority of the fat. Think about it - most of the fat melts into the pan, and I don’t know anyone who’s going to consume all that grease that’s floating around.

Ultimately, you’re ending up with a piece of protein with a little bit of crispy fat, and if you’re not adding carbohydrates to that, it’s not going to clog your arteries.

Plus, the keto meal plan isn’t all bacon. Particularly on my healthy keto plan, I recommend that you eat 7-10 cups of vegetables a day and make sure you get your nutrition from high-quality foods like full-fat organic dairy, and wild-caught, grass-fed, pasture-raised meat, fish, fowl, and eggs.


3. Keto is a recycled Atkins diet

No, it’s not.

Sure, they’re similar meal plans, but they’re certainly not identical (you can find a full comparison between the two diets here). While Atkins also recommends large quantities of vegetables, it is primarily a high-protein diet, not a high-fat diet. This is an important distinction.

As noted above, protein does spike Fat Storing Hormone in the body, and a high protein diet will not allow you to go into ketosis (where your body runs on ketones for fuel rather than glucose). This is when a lot of the health benefits of keto come into play, so the fact that this part is missing from Atkins is a really game-changing distinction.


4. Keto causes ketoacidosis

Anyone who tells you that keto causes ketoacidosis just does not understand keto or ketoacidosis.

Ketoacidosis only occurs if you’re a type 1 diabetic and you fail to take Fat Storing Hormone, so your blood sugars get out of control.

If you don’t have type 1 diabetes, you are not going to get ketoacidosis. Even if you are a type 1 diabetic and you control your Fat Storing Hormone, you’re not going to get it. And you’re certainly not going to get it because of keto.

Just because they both have the same word in them, “keto,” doesn’t mean that they’re the same.


5. High-fat diets will kill you

The Standard American Diet (fat+glucose) can hurt you. Keto won’t.

Yes, there are some studies out there in rats that will state that high-fat diets will kill you.

But if you actually read the study and observe what the mice consumed, you will notice that it wasn’t just a high-fat diet - it was a high-fat, high carbohydrate diet.

That combination - which is more similar to the Standard American Diet than keto - probably will kill you because it combines fat and glucose. This combination is going to:

  • Exaggerate Fat Storing Hormone in your system
  • Contribute to the development of diseases like cardiovascular disease and cancer
  • Lead to weight gain
  • Be associated with greater incidences of depression, depressive symptoms, and anxiety
  • Impair learning and memory

Not great side effects - and decidedly not caused by keto.


6. Our brains run on carbs

This is true. But here are two other important facts:

Fact #1: The majority of your brain can run on ketones. In fact, our brain prefers ketones over carbs. If the brain has a choice - if, for example, you had ketones and glucose in your blood - it’s going to go after the ketones first.

Fact #2: The part of your brain that does need glucose (which is a very small part) doesn’t need to get it from a dietary source. Instead, it can get that glucose from your own stored fat or from dietary fat.

That means that your body doesn’t have to run on carbs if you don’t want it to. Let me explain a little more.

You Can Get Glucose From Triglycerides

In your body, you have triglycerides. Triglycerides are the most common type of fat in the human body. They come from natural fat food sources, they’re present in the blood, and they’re stored inside fat cells when you’re not using them.

Each triglyceride is composed of three fatty acids (which the body can run on) and one glycerol. That glycerol molecule can be converted to glucose. That’s what the brain can run on.

That means that you don’t need external glucose. Your body can make all the glucose you need from your triglycerides.

The Alternative: Ketones

With that in mind, the reality is that your body runs more efficiently on ketones. In fact, ketones are like clean fuel that protects your nerves and fuels your brain.


7. Keto will cause your muscles to shrink

This is absolutely not true.

When you do keto, you actually improve Fat Storing Hormone resistance and increase the absorption of amino acids in your body. Both can help you lose weight and gain muscle (amino acids are the building block of protein, after all).

Personally, I gained nine pounds of muscle on keto. So this side effect is totally false.


8. Keto is not good for the thyroid

This is also completely false.

A high-carb diet actually strains the thyroid and makes it work harder.

Keto, on the other hand, is good for the thyroid. When you go low carb, the thyroid can actually be more efficient and work better. The key here is consuming a well-rounded diet that has all the nutrients your body needs to function well (and you’ll get those in the vegetables and high-quality foods that I recommend on healthy keto).


9. There are no long-term studies that prove that keto is good long-term

Well, we do know the long-term effects of a high-carbohydrate diet. If you look around, the effects are:

  • Diabetes
  • Heart disease
  • Cancer
  • A fatty liver

Knowing those confirmed effects, I’m going to stick with the keto diet.


10. Keto gives you bad breath

Healthy keto will not give you bad breath

Honestly, I don’t know of a lot of people who have bad breath from keto unless they’re doing dirty keto.

If you’re doing the healthy version of keto, I really don’t think you’re going to have bad breath because you’re getting your nutrients, you’re getting into full ketosis, your body is using all of those ketones as fuel, and you’ve adapted enough that you’re actually metabolizing and using those ketones for energy.


11. Keto is not sustainable

Actually, it is very sustainable because you get rid of your hunger and your cravings. The high-carb diet, on the other hand, is definitely not sustainable because you’re hungry all the time and constantly refueling with high-sugar, low-quality food.
