Page "Dieting" Paragraph 13

Normally, when people lose weight, they lose a combination of fat and muscle.

If the diet plan includes a daily caloric intake greater than the basal metabolic rate ( BMR ), the person will most likely lose fat.

In contrast, if the person follows a diet that includes a lower caloric intake than the BMR, this person will lose fat but also a higher percentage of muscle.

Severe diets may make people lose 50 % fat and 50 % muscle weight thus affecting their metabolism because by losing muscle the BMR is affected.
