Muscle Mass

Muscle tissue contributes approximately 20% to your Total Daily Energy Expenditure (TDEE) versus 5% for fat tissue. TDEE is the term used to describe how much energy is used (or how many calories are burned) by an individual during a 24-hour period. Some studies have shown that an increase of about 4.5 lbs of muscle mass through resistance/strength training would increase the resting metabolic rate by about 50 kilocalories per day. In the same way, declining muscle mass slows metabolism, which tends to happen as we age or become less active.
