ADF might work better for you. Basically omad every other day. Really cuts into those fat reserves and Basically gives you guaranteed 2lb/week weight loss if not more. Don’t eat anything m/w/f and then do your regular omad the other days
I do a 5 day water only fast every 3 months and I lose 10 pounds and have kept it off. I would do them more often but life gets in the way. With 2 small kids to look after it can be impossible not to taste food or I just need to have maximum energy levels.
Adf works well. Honestly the fastest way is to just stop eating. I lost weight very quickly doing 72 hour fasts but my metabolism crashed when I got lean and I gained all the weight back plus some. I wouldn’t recommend anything that aggressive unless you’re performing for something in a swimsuit
