In the chart above, you can see the BMI categories. BMI is an objective measure of excess weight, but it doesn’t indicate how much of your weight comes from fat versus muscle.

Muscle weighs more than fat, so if you’re well-trained and muscular, you might have a high BMI without being overweight. That’s why your waist measurement is often a better indicator of whether you should consider losing weight.

A BMI over 25 and a waist measurement over 88 cm for women and 102 cm for men increase the risk of developing lifestyle diseases.

If you want to become healthier and reduce the risk of developing lifestyle diseases, your energy intake must be less than your energy expenditure, so you are in an energy deficit.

The body is quite ingenious; if you eat and drink too much, the extra energy is converted into fat, which is stored in the body's fat reserves for later use.

However, in our time and part of the world, this is not so beneficial, as we never need these extra fat reserves, and over the years, many people gradually get used to eating a little too much every day, resulting in an unhealthy lifestyle.
