Why do some women gain weight on BC yet weight gain is due to excess calorie intake

Question

Hello! as to why some women gain weight when they go on hormonal birth control?

I’m a big fitness person and believe that calories in v calories out is what makes you put on weight. If someone is still working out and their diet hasn’t changed but they began hormonal birth control, why are they putting on weight? How does this happen?

I’m genuinely curious and would love some insight. Thank you.

The hormone can take the body from “Get what we need” mode to “PANIC WE ARE STARVING ABSORB EVERY CALORIE” mode.

So it will both reduce the amount of “wasted” calories from food and increase appetite.
