Insulin, the hormone that makes you fat!


Losing weight is not just a matter of diet or lack of physical activity. Before losing a single gram, it would be wise, or even more useful, to understand the mechanisms of weight gain. Find out in the following how to regulate insulin, a hormone that converts your calories into fat and makes you gain weight!


Insulin is a protein hormone secreted by specialized cells in the pancreas. Its role is to regulate glycemia (blood sugar levels) by allowing excess to be absorbed into fat and muscle cells or stored in the liver. Its hypoglycemic effect (lowering of blood glucose) which stimulates cellular anabolism is vital for a living being


The body needs blood sugar levels to remain stable with a glucose (sugar) index of between 0.80g and 1.20g per liter of blood. Each time this threshold is exceeded, the alert brain tells the pancreas to produce insulin to normalize this instability. The pancreas uses 3 pathways to metabolize ( transform) this excess glucose.

  • To the muscles: When energy is necessary for their functions, the insulin allows the muscle cells to be supplied with glucose. The latter takes glycogen (a form of intracellular glucose) to provide immediately mobilizable energy.
  • To the liver: In order to provide available energy during periods of fasting, insulin ensures the supply of glucose to the liver where it will be stored. This form of storage, called the liver reserve, will deliver glucose if blood glucose levels fall.

However, these reserves are limited, about 100/150g of glucose, depending on the size of the person.

  • To adipose tissue: Once the muscles and liver have filled up, insulin will store excess glucose by feeding triglycerides (body fat). Unlike the liver, the reserves here are unlimited. Regardless of the quantity, the body will create as many adipocytes (fat cells) as necessary.


After each intake of food, blood sugar levels increase due to the abundance of nutrients (carbohydrates, lipids, and proteins). However, after a meal that is excessively high in calories or carbohydrates, the rise in blood sugar becomes too great. Faced with this sudden imbalance, insulin will work to restore blood sugar to a stable level.

As detailed above, glucose will be directed primarily to the muscles and liver. If the latter do not need a new supply, it will be systematically converted into a lipidic substance! In other words, unless you are physically active after your meal (which is inconceivable), the body will store excess energy in the form of fat!


1- Avoid blood sugar peaks!

Avoid processed, overly sweet, or high-calorie foods such as bread, industrial cereals, ready meals, etc. They influence blood sugar levels too much. When preparing your meals, choose foods with a low or medium glycemic index. That is to say, products that only have a reasonable impact on blood sugar levels. Several tools are readily available to obtain this valuable information (internet, smartphone applications, etc.).

2- To lose weight, use glucagon!

Glucagon, too, is a hormone secreted by the liver. Its role is the opposite of that of insulin, causing a rise in blood sugar levels. Its hyperglycaemic function allows the delivery of glucose into the blood from the liver and fat cells. In order for these reactions to occur, space out your meals, avoid inappropriate snacking, keep an eye on your eating habits, and plan fasting phases.

In short, while insulin stores energy by making you gain weight, glucagon releases the reserves and makes you lose weight!

There are simple ways to regulate insulin and consequently prevent the shapes from rounding off. The most important thing to keep in mind is the following relationship: the more you avoid insulin peaks, the more you refrain from forming excess fat!

If this formula is kept to a minimum, your daily expenditure will draw its energy from where it is, i.e. from your own fat stores! A real godsend for your physical improvement goal. To obtain such benefits, here are 4 simple tips that will help you get back into shape.


Insulin regulation is closely linked to your eating habits! To put it plainly, the more carbohydrates (sugar in all forms) you eat, the more insulin you get. It is therefore essential to choose foods with a low to moderate glycemic index. That is to say, products that have little influence on your blood sugar levels.
