I've dropped roughly a stone myself since starting mounjaro about ten weeks back, five weeks at 2.5mg, five at 5mg, and I'm due to step up to 7.5 soon. A lot of people tell me the real drop happens once you move past the starter dose into the 5-10mg range. Exercise wise I don't do much beyond a short walk every other day since work and caring for family eat up most of my time. Honestly weight loss wasn't even my goal, everything else I tried for my blood sugar over the last decade failed completely. This medication turned things around almost immediately. My eating had to change a lot too because of kidney problems, but my glucose numbers are solid now.
