Document Summary

Body weight components: body composition, fat-free mass. About 60% of body weight is water: fat mass. Lean body mass: a subset of fat free mass, muscle mass, organ mass, major determinant of resting metabolic rate (rmr) Increases with gains in fat mass: decreases with age, higher in men than women. Muscle to support burden of adipose tissue. Resting metabolic rate is usually higher in obese people: goal of weight management is to preserve lean body mass (preserve metabolic rate) Can exercise to counteract losing muscle while losing weight. Lean body mass (muscle mass) decreases if someone loses weight. Body fat: some is necessary for normal physiologic functioning, major stored energy reserve compartment. Carbohydrates stored in muscle and liver: under the skin (subcutaneous, deeper to cushion organs (visceral, optimal body fat content: Optimal= the most healthy associated with the best health. Athletes may be the only exception (fat mass/total mass)
