A detailed guide on fat adaptation

Fat adaptation is a process where our body is into ketosis for a longer period and this helps in burning fat instead of carbohydrates


When we follow a low carb diet, the fat-rich ketogenic diet has enormous health benefits that include increased energy, aids weight loss, improved mental health, and decrease in your blood sugar.

The main aim of this diet is to achieve ketosis. Ketosis is a stage where our body and brain starts to burn fat as their major source of energy.

“Fat adapted” is one of the many terms that is associated with this diet, but you may be surprised what exactly it is.

In this blog post, we will explore on fat adaptation, how it is different from ketosis, their signs and symptoms, and whether this diet is healthy.

Definition of Fat adapted:

In general, a keto diet is based on the principle where our body can burn fats instead of converting into glucose for energy.

After some days, we follow a diet which is very low in carbohydrates and rich in fat puts our body into ketosis. Ketosis is a state where our breaks down fatty acid to form ketone bodies that uses them for energy.

“Fat adapted” is a term where our body has reached a state where the fat is burned effectively and uses them for energy. This effect needs more time and research.

How to reach fat-adapted state:

To get into ketosis, you should not eat carbohydrates more than 60 grams and as low as within 30 grams of carbohydrate per day for many days. Ketosis occurs during the period when you starve, pregnancy, infancy, or when you are fasting.

Fat adaptation starts from anywhere between 5 to 13 weeks after your body has achieved ketosis.

Most of the people start losing their weight with a combination of fats and carbohydrates, but for people who follow keto diet burns fat.  Fat adaptation is a long-term process where our body goes through a metabolic adaptation that goes into ketosis. Ketosis is a state where our body burns fat and uses as an energy source.

How is it different from ketosis?

When our body enters into ketosis, our body stores fat and dietary fats are used to convert into fatty acids that are formed as ketone bodies that are used for energy. In the beginning state, this process is inefficient because we are at the initial stage of the keto diet. When you suddenly increase your intake of carbohydrates, it can easily throw your body out from ketosis, because our body prepares to burn carbohydrates. Fat adaptation is a process where our body uses fat as its primary source of energy. This is said to be one of the efficient methods at their initial stage of ketosis that depends on the keto diet our body gets adapted.

Signs and symptoms of fat adaptation:

When our body enters into fat-adaptation, we experience fewer cravings and we feel more energetic, and help you to stay focused.

Decreased craving and hunger:

People who are keto enthusiasts claim that they face reduced appetite and a fewer cravings are one of the significant signs that show that our body is going through fat adaptation.

When you are at the initial stage of keto diet, you are allowed to eat only 850 calories per day is continued until we lose a targeted amount of weight. Our food cravings drop after a significant period of keto diet. However, extreme calorie restriction should not be followed for a longer period, because it might harm our health.

Increase in your focus:

When you follow fat-adaptation, ketosis uses ketone. Ketone has a molecule named beta-hydroxybutyrate ( BHB) that is used to protect our brain and helps in improving the focus.

Improved sleep:

A recent study states that when our body goes through fat-adaptation we face improved sleep and helps us to stay refreshed and relaxed.

Whether fat-adaptation is healthy?

Due to lack of studies, we do not understand the risks that are involved while following keto diet. A recent study also states people who are obese revealed that following the keto diet helped in improving their cholesterol levels, where some other research states that adults who followed a ketogenic diet experienced severe complications like stroke and other heart-related issues.

Precautions and side effects in fat adaptation.

The keto diet is difficult to maintain because during your initial days of keto you get keto flu that includes fatigue, bad breath and some other reports includes damage in liver and damage in the bone. A long-term keto diet is unsafe for people who have type 2 diabetes and people who suffer from gall bladder issues.


Fat adaptation is a process where our body burns fat instead of carbohydrates, and this is a significant benefit of following a keto diet.  When your body reaches fat-adaptation, it showed a decrease in cravings, increased energy levels, and also improved sleep.

More research is needed to understand the long-term effect of a keto diet and how the process of fat adaptation works.
