Visceral fat- (located around organs in abdominal area) does increase health risk. Basal metabolic rate- rate of energy use at rest (and fasting) Thermic effect of food-energy used to digest food, absorb, metabolize and store nutrients.

Appetite- desire to consume specific foods triggered by external cues independent of hunger. Hunger- desire to consume food that is triggered by internal physiological signals. Anaerobic- without oxygen; uses glucose; generates lactic acid. Aerobic-with oxygen; uses carbs proteins and fat; produces more atp.
