HSC 106QR Lecture Notes - Lecture 2: Bioelectrical Impedance Analysis, Body Composition, Weight Loss
Basic concepts of weight management: body composition. Fat-free mass: bone, water, muscle, connective tissue organ issues, and teeth. Essential fat: necessary for body to function. 8-12% in women: energy balance is key to keeping a healthy ratio of fat and fat-free mass. Energy in= energy out, you maintain your current weight. Energy > energy out, you gain weight. Energy in < energy out, you lose weight. Evaluating body weight and body composition: overweight: total body weight above recommended range for good health, obesity: a more serious degree of overweight, body mass index (bmi) Based on the concept that weight should be proportional to height. Body composition analysis: most accurate and direct way to determine percent body fat, hydrostatic (underwater weighing, bod- pod air to measure, skinfold measurements. Thickness of fat under the skin: bioelectrical impedance analysis. Excess body fat and wellness: the health risks of excess fat.
