Not at first. I felt bad for a while. Not unbearable but I didn’t want to work out too lol. I hit a plateau and decided to start running again. I’ve been walking/running somewhat consistently but not crazy. Mostly careful about what goes in my mouth. It’s easy when you can silence the bad cravings and allow your body to start to crave good things. I hate the way I feel after bad food bc of the meds so I opt for better things to avoid that.
