The amount of calories that your muscles consume.

The amount of calories that your muscles consume.

The human daily needs of TDEE or Total Daily Calorie Expenditure are divided into four parts. The TEF or Thermic effect of food, which is about 10% of your caloric needs, is the calories that the body consumes to digest and represent food, knowing that protein is the highest varieties in the thermal effect, since about 30% of the protein calories the body consumes for digestion And acting (source).

And thus the calories that the muscles consume, and the rest of the body’s organs fall under the category of BMR or what is also called the REE and is Resting Energy Expenditure, and this scientific research published in 2001.

It should be noted that muscles raise your caloric intake in ways other than increasing BMR or increasing metabolic rate, as muscle tissue makes your weight "heavier", and when your weight becomes heavier, your body consumes higher calories for movement.

Whenever you lose your weight in a diet, your body becomes “lighter” and thus your burning calories and fats decreases. If you weigh 100 kilograms, your caloric consumption will be 2500 calories (for example), when your weight decreases to 90 kilograms, this rate will decrease to maybe 2400 calories And therefore if you eat the same calories you will burn less fat from your body, iron exercises increase your muscle mass and prevent this decline in the consumption of calories.

Also, the iron exercises themselves burn calories, and the process of demolishing and building muscle burns calories.
