No relation between birth-control pills and weight gain

These comprehensive experiments took in to account weight, activity level, lean muscle mass, food intake, and body weight of the animals. Female rhesus monkeys, whose reproductive systems are the same as that of humans, got birth-control pills and monitored for over 8 months. It was found that the birth-control pills had no adverse effect on their weight.

The conventional wisdom that said hormones in birth-control pills cause females to gain weight does not stand the check of science. Recent experiments conducted by Oregon National Primate Research Study Middle on rhesus monkeys demonstrate that birth-control pills have no relation to increasing weight.

Researchers say that females, ranging from teenaged girls to grown females, gain weight due to natural changes in the body and blame it on birth-control pills. They also believed in most cases, females getting little physical exercise and eating much junk food are more to blame than birth-control pills
