The 10 Biggest Ketogenic Diet Mistakes

The 10 Biggest Ketogenic Diet Mistakes

The ketogenic diet is a powerful tool to help boost fat burning and help the body heal from chronic disease. I have used this approach clinically for years with amazing results and personally engage in a ketogenic lifestyle. While the benefits of keto are real, there are 10 common ketogenic diet mistakes that may prevent someone from experiencing the full benefits.

When someone comes to me asking why they are having trouble losing weight or feeling abundant energy on a ketogenic diet, I investigate to find out if they are making these ketogenic diet mistakes.

Not Enough Calories/Fats

One of the most common ketogenic diet mistakes I come across is that people simply do not eat enough calories, especially from healthy fats. While fasting and calorie restriction have their place, prolonged calorie restriction can actually be very stressful on the body and lead to many negative effects, most notably lethargy, adrenal and thyroid problems.

Most people do great with reducing carbs and sugars in the diet, but are hesitant to increase their fat intake to 70-80% of their total calorie intake. Part of this has to do with the demonization of cholesterol and saturated fats in the 80’s and 90’s, and even to an extent still today. There were some questionable biases present in these original studies and more recent evidence actually shows that low-carb, high-fat nutrition plans are much more effective for health than low-fat diets are (1, 2).

Be generous with your fat intake. Healthy fats should comprise a major portion of every meal you eat so that your body can take those and turn them into ketones for energy. If you are feeling hungry after meals, increase fat intake. If you notice you are overly full or notice a lot of digestive upset, you likely have overeaten.

Not Properly Hydrated

One of the most common complaints on a ketogenic diet is constipation. If you are not moving your bowels 1-3 time a day, you likely need to increase your water intake. In fact, this is one of the ketogenic diet mistakes that is probably just as common as not eating enough fat.

I always recommend consuming an absolute minimum of half your bodyweight (lbs.) in ounces of water daily. Ideally, you want to shoot for your full body weight in ounces. For example, a 150 lb. individual would shoot for 150 ounces of water throughout the day.

Something else that is critical is to only drink away from meals. For small meals, separate hydration by an hour. For larger meals, you may need up to 2 hours to allow digestion to complete before hydrating again. This goes for before meals as well.

One of the most helpful strategies I have found is to actually start your day with super hydration first thing in the morning. Before taking a bite of food, try consuming 16-32 oz. of water. You will likely notice you have more regular bowel movements, your skin looks healthier, and in general you feel more energy.

Not Consuming Enough Electrolytes

This one goes along with our other ketogenic diet mistakes in that you need plenty of water, but you also need the right minerals in order to be properly hydrated. These ketogenic diet mistakes made together will destroy your fat burning potential. Your nervous system uses water and electrolyte minerals to actually send messages. With poor hydration and low electrolyte levels, you get poor energy production and will not be able to take full advantage of the benefits of a ketogenic diet.

Additionally, on a ketogenic diet insulin levels drop. This is important to note because insulin signals the body to hold on to water and minerals. When insulin levels drop, we excrete excess water and minerals which need to be replace much more frequently (3, 4).

This is why I recommend using a high-quality sea salt (such as this one) in water and on foods. Use it generously to taste. Many people notice that when they are not quite feeling their best on a ketogenic diet, that increasing their salt intake actually makes a huge difference in how they feel.

Other great sources of minerals include leafy greens, sea vegetables, cucumbers, celery, and bone broth.

Eating Too Many Carbs

This is one of the ketogenic diet mistakes that is pretty straight forward, but if you are eating too many carbs, your body will burn them as energy instead of the fats you are consuming. If you are just starting out your keto journey it is important to really limit net carbs to about 20 grams or less per day for at least a month.

Dropping carbs below 20 grams a day and consuming plenty of healthy fats will help your body relearn how to burn fat for energy over a 2-4 week span. Most people have been burning sugar as energy their entire lives and don’t realize that this metabolic shift needs to be stimulated by really limiting carb intake. This is what I call a Keto Metabolic Makeover and you can read about how to do that here: Keto Metabolic Makeover.

After about a month of being strict on carb intake, you can begin what is called a carb cycling program where you consume a higher carb meal once a week using things like berries, sweet potatoes, and sprouted grains if you tolerate them well.

Too Much Protein

A common misconception is that a ketogenic diet is simply a low-carb diet and that fat and protein can be consumed in unlimited quantities. Many people do not realize, however, that consuming too much protein may actually be preventing you from entering into a state of ketosis. This is because, when consumed in excess, amino acids will be converted into glucose which the body burns for energy instead of dietary fats (5).

Additionally, excessive protein intake can be acid-forming in the body. Consuming too many acid-forming foods on a regular basis can actually contribute to chronic fatigue and muscle pains, such as fibromyalgia.

A good protein goal to shoot for would be around 1 gram per kilogram of bodyweight. This means someone with 160 lb. bodyweight which equates to about 73 grams of protein per day.

Take your weight and divide by 2.2 to figure out the grams of protein per kg of body weight.  Aim to get this on your lighter workout days.  If you are doing more strength training or trying to gain muscle, bump it up to 1.6 grams per kg.

If you are a very sedentary individual who does not do much exercise, your protein requirements will likely only need to be around .6-.8 grams of protein per kilogram of bodyweight.  Out of all the ketogenic diet mistakes this is probably the most common because we often associate high fat foods with high protein.

Too Much Stress & Poor Sleep

Stress and poor sleep seem to be getting to everyone. These are two big ketogenic diet mistakes, especially for those just starting out. For those who have never followed a ketogenic diet and need to go through the metabolic reset process I recommend here, it is best to wait until you have a month where you can reduce your stress load.

After becoming fat-adapted you will likely notice that you are more able to meet stressful day-to-day demands.

This is because the adaptation process can be someone stress-inducing to the body and excess stress may actually prevent you from being able to get into ketosis. Highly stressed people tend to have rapidly fluctuating cortisol levels that through off blood sugar balance. For these people, when blood sugar goes too low, instead of producing ketones it could set off a stress hormone cascade and hypoglycemia that leaves you feeling chronically fatigued.

Another big factor here is sleep quality. Poor sleep is another factor that throws off blood sugar regulation and may negatively affect your ability to get into ketosis.

Poor Bowel Motility

This is one of the least discussed ketogenic diet mistakes and therefore it is often overlooked. This is because many people would never even think to consider that their bowel movements may be preventing them from getting into ketosis.

Constipation is common on a ketogenic diet. When excess waste backs up in the colon, unwanted microbes can overgrow and the body will tend to produce higher amounts of stress hormones, throwing off blood sugar balance.

The most common things that need to be addressed for constipation on a ketogenic diet are poor hydration, not enough fats, and not enough fiber. Start the day off with the hydration strategies discussed earlier in this article and aim to have a bowel movement within an hour of being awake. 2 or even sometimes 3 solid movements a day is a good sign that you are not having any motility issues.

Additionally, magnesium supplementation can be absolutely amazing for improving bowel motility and so much more. Magnesium is a powerful supplement that we all can benefit from, especially on a ketogenic diet.

Too Much or too Little Exercise

If you are a high-level athlete or workout 5-7+ days per week, then the ketogenic lifestyle may not be for you. This amount of physical activity and stress is not conducive to being in a ketogenic state and these individuals may do better on more of a low-carb diet (6).

In fact, many people are surprised to find that on a ketogenic diet they are able to work out less and feel more profound benefits from their workouts. Personally, I only do 3-4 strength workouts per week and I have found that this is what makes me feel my best on a regular basis.

On the other hand, being sedentary all day is not good either. At an absolute minimum, you need to get 20 minutes of low-intensity movement every day. This could simply be taking a walk or making sure that you are standing up and moving around throughout the day.

Doing so will help make sure your tissues stay oxygenated and your lymph fluid gets stimulated by muscular contractions. Poor oxygenation of tissues will not be conducive to ketogenisis as the mitochondria actually need oxygen in order to make energy from ketones. This is a process called oxidative phosphorylation. Additionally, regular exercise will help upregulate a protein called GLUT-4 which acts to pull sugar out of the blood stream and store it in muscles or the liver as glycogen (7).

Having higher Glut-4 activity can essentially allow your body to handle slightly higher amounts of carbs while maintaining ketosis.

Poor Quality Foods

Something I always hate seeing is someone who claims to be on a ketogenic diet while consuming lots of processed vegetable oils and meat products. Technically yes, you can be on a ketogenic diet by eating salami wrapped mozzarella cheese from the gas station, but is it worth it?

To me the ketogenic diet is such a powerful life-giving and healing tool with profound health benefits. When someone goes about a ketogenic diet by consuming these highly toxic and inflammatory foods, we lose so much of those benefits.

It is absolutely critical that the fats you are consuming are healthy and natural fats. Fats derived from things like coconuts, avocados, olives, and pasture-raised animal products.

Additionally, I always recommend consuming organic produce and pasture-raised animal products (meat, dairy, eggs). On top of these things, consuming plenty of nutrient-dense vegetables and antioxidant-rich herbs and spices take the benefits of a ketogenic diet to the next level.


There are a number of ketogenic diet mistakes that will inhibit your ability to burn fat and experience the full benefits it has to offer. Those listed above are the most common and the ones that will most likely hold you back from reaching your health goals.
