Document Summary

Everytime we use atp- heat is also used. Thermogenesis- creation of heat (which is a by product of metabolite processes leading to atp. Healthy circumstances = balance maintain a stable weight. Lean body mass depends on muscle mass and is metabolically more active then adipose mass (exception is brown adipose tissue which has a high % of mitochondria in it) Lean body mass explains 82% of variance in ree (basal and expenditure: resting energy expenditure = 60-65% Energy used at rest: thermic effect of feeding = 5-10% Physical activity= 25-30: varies depending on intensity and amount, athletes in training have a very high amount, adaptive thermogenesis (-5-5%, we can adjust oour overall caloric needs depending on health, illness, diet, environment etc. Partly related to brown adipose tissue and genetics. Fat storage in healthy weight men is 6-20kg of body fat. Physical activity is between and within, neat (non exercise activity thermogenesis (fidgeting, walking)
