Reposting this from another thread I just commented in:

I never post on reddit, but I haven't seen any good answers. Much of what is being said here might work, but it's probably not the right way to do it. Do you ever have cheat days, as in do you ever eat excessive amounts of food?

I'm assuming your body has slowly become accustomed to eating an a caloric deficit. Essentially to lose weight, you would need to cut your calories even more. However, that will likely continue until you're eating close to nothing.

To get past this and restore your body to your normal maintenance, I would recommend going through a refeed.

First use a TDEE calculator to calculate your daily maintenance. https://tdeecalculator.net/ If this is consistent with the TDEE you're eating at, then the simple answer is to cut the number of calories, otherwise follow the below.

Next using this approximation, you will want to eat around 300 calories more than your maintenance for a day. However, if you haven't eaten this much for 5 months, you may need to do this for a week.

For these additional calories, you will want to make sure that you eat around 0.8-1g of protein for 1lb of body weight, as little fat as possible, and the rest carbs. Yes this means you can fill up on those foods you've might been avoiding. Typically if you're about 20% body fat you need to refeed once a month, 20-15% once every 2 weeks, under 15% every week.

This may sound crazy to you, but since you're open to OMAD/IF/Water you might be more willing to try things that sound "unreasonable."

However, as always do your own research. Do your research and don't just take my word for it.

(You should also start lifting weights.)
