VSG + Intermittent Fasting

Hello everyone! So I got the VSG around 15 months ago and I’m starting to notice weight gain, even when “dieting”. I saw someone online suggest doing intermittent fasting, because since our portions are already controlled due to the surgery, the only variable left to control would be the frequency of eating (which is what I’m struggling with). I still have around 20lbs to lose to reach my goal weight of 200lbs! Pls lmk if anyone has tried it/if you would recommend doing it!
