Page "Dieting" Paragraph 12

The Basal Metabolic Rate, which is the amount of calories the body expends at rest, meaning without performing any physical activity, is influenced by the person's total weight and total amount of muscle.

The more muscle, the more calories a person can burn naturally.

When the amount of muscle is increased, then more calories can be ingested without gaining weight.

Conversely, if the amount of fat is increased, increasing the number of calories ingested will only add weight.
