Someone please give tips on how to lose arm/belly/face weight!!

I used to be so skinny 5’3 122 lbs, now I weigh around 155 due to being on depo shot for 1 1/2 years, I was on the pill for a little over a year now because I believed the depo made me gain serious weight, I’ve been off the pill for almost 2 months now just trying to give my body a break and I haven’t really lost anything. Help!
