Which birth control makes you gain weight?

Answer 1

Women on the Birth Control pill don't gain any more weight than women who aren't on the pill in controlled studies. (In the US, people are gaining weight at a fast clip, whether or not they use birth control pill). In the original studies of Depo Provera, a third of the women gained, a third lost, and a third stayed the same. If you don't change how you eat or exercise, you wouldn't expect to gain on the shot.
