Weight gain sometimes results directly from the physical changes of puberty. Basal metabolic rate the minimal amount of energy used by the body during a resting state.

Body mass index (bmi) a (cid:373)easure of a(cid:374) i(cid:374)di(cid:448)idual"s (cid:271)ody fat, the ratio of (cid:449)eight to height, used to gauge over weight and obesity. With this definition, more than 1/6 of adolescents in the us are obese and another 15% are at great risk for obesity. Obesity is considered the single most serious public health problem afflicting american teenagers. Current research indicates that obesity is a result of the interplay of genetic and environmental factors. Recent neuroimaging studies find that individuals at risk for obesity show relatively greater a(cid:272)ti(cid:448)atio(cid:374) of the (cid:271)rai(cid:374)"s re(cid:449)ard (cid:272)e(cid:374)ters i(cid:374) ge(cid:374)eral, heighte(cid:374)ed respo(cid:374)ses to i(cid:373)ages of food, and poorer impulse control.
