Document Summary

Overweight: (cid:271)ei(cid:374)g (cid:449)ay too hea(cid:448)e for o(cid:374)e"s height. Energy balance: amount of energy consumed in the diet compared with amount expended by the body after an amount of time. Bomb calorimeter: instrument used to determine the energy content of food. Measures heat energy released (cid:449)he(cid:374) a dried food"s (cid:272)o(cid:374)su(cid:373)ed. Basal metabolic rate (bmr): rate of energy expenditure under resting conditions. Estimated energy requirement (eer): a(cid:373)ou(cid:374)t of e(cid:374)ergy re(cid:272)o(cid:373)(cid:373)e(cid:374)ded (cid:271)y the dri"s to (cid:373)ai(cid:374)tai(cid:374) (cid:271)ody (cid:449)eight healthy by age, weight, gender and activity levels. Body mass index (bmi): (cid:373)easure of (cid:271)ody (cid:449)eight i(cid:374) relatio(cid:374) to height that"s used to (cid:272)o(cid:373)pare (cid:271)ody size (cid:449)ith a standard. Skinfold thickness: measurement of subcutaneous fat used to estimate total body fat. Subcutaneous fat: adipose tissue that"s lo(cid:272)ated u(cid:374)der ski(cid:374) Visceral fat: adipose tissue that"s lo(cid:272)ated i(cid:374) a(cid:271)do(cid:373)e(cid:374) arou(cid:374)d (cid:271)ody"s i(cid:374)ter(cid:374)al orga(cid:374)s. Set-point theory: when people finish growing, their weight remains stable for long periods despite energy intakes and output.
