The Keto diet and intermittent fasting are two prevalent health trends today. Many people are trying out one of these diets to see if they work.

Both of these diets have been proven to work. Now the question remains between keto and intermittent fasting, can you combine the two?

Some dieters think that combining the two diets would help them lose weight faster. We will break down each of these diets and show you the pros and cons of combining the two.


Keto Diet

Keto Diet

The Ketogenic diet is a diet that is high in proteins and fats. This diet does, however, restrict your carb intake daily. Your meals would contain about 70% fat. There would be very low carbs and medium protein in your meals.

The daily total carb intake is less than 50 grams. This amount forces the body to use fats and no sugar as your body’s source of energy. Ketosis is the state when your body breaks down fats to form ketones. These ketones serve as fuel for your body.

The Keto diet was developed to help people with short-term weight loss. There are several other benefits to the diet as well.

Many doctors have used the Keto diet to treat their patients that have neurological disorders. Many children with epilepsy have been treated with the keto diet too.

Intermittent Fasting

Intermittent Fasting

Intermittent fasting is a diet or an eating method that cycles between restricting calories, fasting, and average food consumption. This diet has helped many obese adults lose a lot of weight and keep it off.

There are several different types of intermittent fasting. Some of the routines include the 5:2 method, the warrior diet, alternate-day fasting, and the 16/8 method.

The 16/8 method is the most popular. This is when you are eating during an eight-hour time range. Then you will fast for 16 hours.

In intermittent fasting, the fasting technique is used to help you lose weight. The food cycles allow the body to use the fact that it has and burns it faster.

This will, in turn, speed up the weight loss, and your body fat mass will improve. This type of fasting helps with weight management, and it gives you many health benefits too.

The Keto diet has been dangerous for those who have type 1 or 2 diabetes. Blood sugar and insulin regulation are significant, and diabetics can cause strange side effects.

Some of these side effects are fatigue, brain fog, dehydration, bad breath, flu-like symptoms known as the “keto-flu.” The combining of both the diets is not an easy one. There are several constraints when it comes to these two diets together.

For keto dieters, they have shallow carb limits. Many people are unable to stick to the low-carb diet in the long term. Adding intermittent fasting to the mix can be too much for them as far as time goes. Once this happens, the diet can discourage you and make you go back to your regular eating routine.


To sum it all up, the Ketogenic diet and intermittent fasting are both two trending diets. Both of them offer several benefits and help people lose weight. Some people want to know if the keto diet and intermittent fasting can be combined.

Some of the benefits are short-term unless you have the discipline to stick with it throughout. For the most part, the combination of the diets is safe.

However, if you have a condition such as heart disease or diabetes, contact your doctor before you begin either diet. Just because it is safe to combine both the Keto diet and intermittent fasting, keep in mind that these two may not work for you or everyone. We all react differently to diets, and our bodies are different.

Many people doing the keto diet have a hard time fasting, and the opposite effects have occurred. Combining the two diets may cause irritability, overeating, and more fatigue.

If you follow a keto diet, this may be just what you need to lose the weight needed to be healthier. Yes, combining them will help you lose fat quickly, but the result may end up with you gaining it back from overeating.

We suggest talking to your primary care physician to get advice on which one is better for you. Good luck on your weight loss journey.
