There has been a lot of talk lately about exogenous ketones, a ketone-based product that is marketed for the purpose of losing weight and especially body fat. Basically, taking these ketones would have the same weight loss effects as a ketogenic or general carb-free diet. But is it really so? Let’s try to understand it together.

WHAT ARE EXOGENOUS KETONES

Exogenous ketones, which can be sold in the form of ketone salts or ester ketones, are fully ketones, i.e. substances that the body normally produces for energy purposes if put in conditions of absence of carbohydrates or fasting.

One of the advantages that is obtained when the body enters ketosis (ie produces ketones) is that after an adaptation phase in which it optimizes their use for energy purposes, we tend to feel less hungry. This mechanism is called “fat-adaptation”, ie adaptation to fats.

Essentially, since these ketones are derived from fats, when the body uses these for energy, it means that it is no longer using carbohydrates for energy.
But at the same time he no longer feels the drops in energy typical of the first days of a carbohydrate-free diet.

Now, exogenous ketones are ketones that come from the outside, that is, in supplement form. Therefore they are not produced by our body, those food conditions I mentioned at the beginning must not occur.
We introduce them via a supplement and the body should use them for energy purposes. And as a result, we should feel even less hungry over time.
Hence one of the reasons for weight loss.

Ketones, also called acetones, produced by the body, are different. Generally those frequently marketed among exogens are D-Beta Hydroxybutyrate and Acetoacetate.
These substances push the body to use fats better for energy purposes.
Now that you know what exogenous ketones are, let’s see if they really make you lose weight.
