Document Summary

Overview of food intake, energy and factors influencing metabolism. Factors that stop eating: satiety (feeling of fullness during eating, satiation (how long a person is full for following eating) Thermogenesis: thermogenesis the burning of energy for fuel. Basal thermogenesis: the minimum energy expended to keep a resting, awake body alive, makes up 60-70% of energy consumed. Includes energy needed for maintaining a heartbeat, respiration, body temperature: the amount required varies between individuals. Exercise induced thermogenesis: amount of energy burned when completing physical activity, energy expenditure is increased beyond bmr, varies widely among individuals dependent on muscle mass %, activity levels, fitness, more activity = more energy burned. Lack of activity = decreased energy expenditure = obesity. Diet induced thermogenesis: aka thermic effect of food (tef, amount of energy lost to consume and ingest food, a(cid:374)alog(cid:455): (cid:862) ales ta(cid:454)(cid:863) of total e(cid:374)erg(cid:455) (cid:272)o(cid:374)su(cid:373)ed accounts for 5-10% above total energy.
