Document Summary
Energy balance = energy in - energy out. Positive/negative energy balance: what you would expect from ^^ Energy out (a) basal metabolism - energy to maintain life processes (b) thermic effect of food - energy cost for digestion. ~10% of kcal eaten (c) adaptive thermogenesis - (i) (i) (ii) (iii) (iv) (v) Not usually included in energy calculations (d) physical activity - (i) Running 10 mph (ii) walking 3. 75mph (iii) walking 2. 5mph (iv) 70% of total energy use by body depends on lean body mass. Though we can"t answer precisely why , beyond that obvious, we eat, but most importantly: the hypothalamus is a brain center that controls water balance, body temperature, and hunger. Pair-feeding - an experimental method in which food intake or energy (calorie) intake are limited to be the same between animal groups and to exclude effects in the animals by differences of food (energy) intake.
