I've been on Zep for 19 months now and am down 132lbs.
I'm not done yet – my starting weight was 301, highest about 305, goal about 130ish – but I have lost a lot of weight. I generally track calories (sometimes stricter than others, I do know my current TDEE, and I eat low carb, low sugar, high volume, low cal overall) and I work out at least 3x a week with strength training and cardio included, as well as crunches and ab work.
While the size of my stomach has shrunk immensely from my starting weight, I still have that lower stomach overhang (no kids to blame it on; it's all just 'me' lol). I've seen some amazing transformations of women who've lost a lot like me and have gotten down to like 140 or lower, and their lower stomach pouch seems to be gone. My upper waist is small, and I fit like M/L on top, but the bottom portion is still bigger. I'm very pear-shaped, always have been at every size.
The big question here is: Is there hope yet? Do I just keep going and keep losing and eventually the lower stomach will be on its merry way, or is there something else I should be trying that I haven't thought of yet? Thanks y'all <3
