Document Summary
Energy intake = bmr (+ nonexercise thermogenesis) (+ thermic effect of food) + physical. Activity +/- stored excess energy (weight gain in the case of infants, children, pregnant and lactating women) When stored excess energy = 0 (stable weight), Mj/kg) by the fraction composition of each component. The use of energy to maintain body function at rest, most accounted for by organs and muscle (fat-free mass) Bmr decrease when energy intake remains below needs for prolonged periods. Bmr increase during overconsumption (thermogenesis: heat of eating) Calculating your eer (see equations on figure 9. 6) Kg = lbs/2. 205; m = inches x 0. 0254. Obese over 30 (3 categories: 30-34. 9, 35-39. 9, >40) One pound of adipose fat = 3500 kcal. The mechanisms that defends against weight loss are stronger than those that prevent weight gain. It is so much easier to gain weight than lose weight because the body likes to retain and store its energy.
