What Is Fat Fasting, and How to do it?

Ever wondered how food tastes without Fat? It’s like cardboard i.e. tasteless. One can experience this, by eating chicken breast which is very low in fat.

Naturally, food never comes in either fat or carb or protein. In nature, food always comes in a combination of protein +fat+ carbohydrates. Fat is a taste enhancer in most of the foods, just like salt and sugar.

Broadly speaking animal products are high in fat whereas plant-based products are high in carbohydrates.

What Is Fat Fasting?

It is very similar to the ketogenic diet, “in which person eat food high in fat and low in carbs”. Fat Fasting should not be confused with “intermittent fasting” which does not allow any kind of eating.

Dr. Robert Atkins, the author of the book Dr. Atkins cc, first stated this concept to break weight loss plateau and reset body hormone imbalances.

Fat fasting can typically last for 2-5 days which depends on your target weight loss and lifestyle choices.

On a particular day, a person can have only 1000 to 1200 calories per day with most of it coming from Fats. You can divide those calories into multiple small meals or can have a single meal.

It is different from intermittent fasting. But like fasting, it pushes the body in a ketogenic state where the body generates ketones for energy in the absence of glucose. so technically you get similar benefits like fasting.

In the long term, intermittent fasting will be more effective in weight loss compared to Fat fasting. On the other hand, fast fasting is much easier to follow on.

How fat fasting work?

As most of you already know insulin is the hormone responsible for weight gain and loss. Carbohydrates aka Sugars are responsible for insulin response. If you can stop this insulin response you already losing weight.

Insulin controls excess blood sugar and stores extra blood sugar in body cells by converting it into body fat. When insulin present in the blood, it prevents the body from utilizing this stored fat for energy purpose. But in the case of dietary fat, no insulin is produced inside the body. Excess fat stored in the liver for future use or flushed out of the body.

In “fat fasting” we try to achieve the same thing, we only eat food high in fat with low or no carbs in it for 2-3 days to achieve expected weight loss.
