Fair call. Was curious because while I know correlation does not equal cause, my (ex) GF went from 58kg to 64kg very quickly when she got the Implanon thingywatsit. Diet didn't change much - if anything got healthier coz she had to eat what I provided lol, and she was doing more exercise given free access to gym at her work. She's back down to 60kg now that she's got it removed, though since having f**ked the relationship with me and going her own way, her eating habits have gone to shit rofl.
