Story of a slow responder here. Started at 285lbs with BMI around 36. Was at 300 at my heaviest last Oct-Nov when I began OMAD fasting and moving more which got me down to my current starting weight by January. For the past four months on OMAD I've been completely stalled even with occasional 36-hour fasts and more walking. Started reta two weeks ago and also ramped up activity with rowing machine Monday through Friday plus kettlebell workouts Monday Wednesday Friday. Week one I did an initial 1mg shot waited four days to watch for sides then another 1mg. Week two I'm now doing 2mg every seven days as the plan for the rest of month one. Scale has barely moved sitting at 284 thanks to less food and harder workouts. I do feel more satisfied right away during OMAD meals than before and sometimes need to stay hydrated but otherwise hardly any sides. Just focusing on getting active and hoping to finally see some real movement from the reta.
He's clearly just frustrated that it didn't work for him.
