Document Summary
Visceral fat is associated with negative health consequences. Fat cells involved with visceral fat are more metabolically active: increases risk of death from all causes, metabolic syndrome, fat distribution. Apple (beer gut shape; visceral; men) v. pear (butt and thigh fat; subcutaneous; women) Factors affecting distribution: high alcohol consumption: upper body obesity, evaluating risks from body fatness. Bmi: waist circumference, decrease risk profile, energy budget, change in energy stores = energy in - energy out. Bioelectrical impedance: dual energy x-ray absorptiometry (dexa) Skinfold thickness: hunger, response to physiological need, chemical messengers, hypothalamus, ghrelin (opposes weight loss, the body"s response to energy surplus, protein broken down into amino acids. Excess converted to glucose or fat: fat broken down to glycerol and fatty acids. Excess stored as body fat: carbohydrate broken down to sugars. Excess converted to glycogen or fat: alcohol used for fuel or converted to fat, achieving and maintaining a healthy body weight, three efforts.
