Slow responder here. Starting weight 285, BMI about 36; I peaked around 300 last Oct-Nov, then started OMAD fasting and moving more and reached 285 by Jan. Four months of OMAD later I'd stalled completely, even with extra walking. So two weeks ago I began reta and stepped up my activity a lot (rowing machine on weekdays, kettlebells Mon, Wed, Fri). First week: one 1mg shot, then a 4 day wait to watch for reactions (none), then another 1mg. Second week I moved to 2mg every 7 days for the rest of month one. The scale has barely budged (284 now, thanks to less food and harder workouts). I feel sated faster in my OMAD window and need to drink enough, but side effects are nearly nil. Now I'm throwing myself into activity and hoping, impatiently, that real results appear as month 1 closes.
