But do you eat your 1600 cals in the 4 hours? Or do you undereat and that is causing you to break your fast early.
Sounds a lot like my 1000 cal omad experience where I ended up bingeing because it was just too little food for me. I upped my intake in my eating window and everything is fine now.
Have you thought about maybe doing 18-6 or even 16-8? Those few extra hours might make it easier to be consistent. I’ve done 20-4 before for a few months and found that I couldn’t be consistent with it. Changed to 18-6 and I’m finding it a lot more manageable for my lifestyle. IF has definitely helped even with 18-6 I’ve lost 25 lbs over the last 2 months (along with CICO, lots of water and exercise). Good luck!
Being angry at yourself is understandable, at the same time its important to not get caught up in the day-to-day and realize how much progress is implicit in your new way of thinking. You say you broke your fast with a kiwi? I bet a year ago youd’ve said a twinkie or something. The fact you’re already thinking to “eat a kiwi” as opposed to some junk means you’re by default on the right track. Thats wonderful, keep that up.
We all understand this is just a calories game, and different routines work better for different people. I’d encourage you to keep trying different routines if the one you’re doing isn’t working. Experiment with various eating windows and styles of eating. Mixing it up also helps keep diets interesting. short fasts, long fasts, paleo, medetteranian, keto, weight watchers points, whatever. Personally it took a month of trying different stuff week by week to find one that really worked. And mixing it up kept weight loss kinda fun.
Keep fightin the good fight
It sounds like the binging was more from under eating than OMAD.
My plan is, when I fast, I fast clean. Water and 1 espresso daily. That’s it.
During my OMAD eating window, I always break my fast with something healthy. I eat a small snack to break fast if I want it, one main meal that is healthy, and then I can have dessert if I want it. I have slowly been making dessert healthier (gelatin made with 1/4 c fruit juice, some fruit). And I avoid high fructose corn syrup and artificial sweeteners.
This has helped me slowly curb binging/feeling out of control. For the first time in forever, I can buy a package of something sweet and not automatically eat the whole thing the first day. Weight loss has been slower than I wanted but that in and of itself is a huge win for me.
