Ketogenic diet: complete guide to enlighten you

Does the ketogenic diet and the keto diet speak to you?

Focused on restricted consumption of carbohydrates and a marked preference for lipids, it promises fat reduction without too much deprivation. The key: Weight loss and better physical shape.

However, while some people love it and swear by it, others, however, remain more wary and hesitate to get started.

So, is the ketogenic diet really a good idea? Does this diet help you lose weight? How ? What are the benefits and what foods to favor and avoid?

We tell you everything you need to know about this diet that is all the rage.

What is the Ketogenic Diet?

The ketogenic diet , or keto diet , is based on a revolution in the way we consume our food. Originally developed for therapeutic purposes, it has been found to be associated with many benefits as well as weight loss. This is why it was brought back into the spotlight...

The basic principle? Dramatically reduce carbs, green light fats, and maintain adequate protein. In other words, it is a change in nutritional direction that gives pride of place to fat. 🧈

So okay, we're eliminating carbs and saying goodbye to sugar, but it's hard to believe that you can lose weight while still eating cheese and butter, right?

However, this is what the ketogenic diet offers and this for a very specific reason: by limiting carbohydrates, the body is deprived of its usual source of energy, glucose. This is where the magic (or science, rather) happens: the liver kicks in, converting the fats you consume, but also those stored in the body, into an energy alternative called ketone bodies.

This is called the state of ketosis.

The state of ketosis = the basis of the ketogenic diet

Think of it like your body switching from gasoline (glucose) to diesel (ketones) – a transition that has a significant impact on how your metabolism works (your engine).

Here it's all about the fact that ketone bodies, rather than glucose, become the main source of energy.

And guess what? These little companions have a special affinity for fat cells.

Indeed, in the absence of these carbohydrates, the body switches to using fat as its main source of energy. These lipids undergo breakdown to form “ketone bodies” which then become the main source of energy for cells.

Did you follow? 🤔 In other words, by adopting the ketogenic diet, you encourage your body to consume fats, including those that are stored.

But the craze around this diet is not limited to weight loss alone. Although popular in this area, the ketogenic diet has also attracted interest for its purported benefits in mental and athletic performance or blood sugar regulation.

Benefits of the Ketogenic Diet

The ketogenic diet was not originally designed for weight loss.

Its initial development was therapeutic to relieve certain ailments or diseases.

So, what are the other benefits of the ketogenic diet?


As we have seen, the ketogenic diet promotes sustained weight loss by encouraging the body to burn fat as its primary energy source. By reducing insulin levels due to the sharp reduction in carbohydrate consumption, it creates an environment conducive to the mobilization of fat reserves.

Blood Glucose Stability

By limiting carbohydrates, the ketogenic diet helps maintain stable blood sugar levels. This can be particularly beneficial for people with metabolic disorders or looking to regulate their blood sugar levels.
