Honestly, you sound like you are doing the right things. Keep exercising with the occasional extended fast. Great job with those! I would however add a food diary, be honest about every bite and weigh the food to get an accurate calorie count. Do this for a week or two just to get an idea of where you may be eating too much and where you are willing to cut back. I would also suggest a TDEE calculator to give you an idea what you should be eating. https://tdeecalculator.net/I believe in you!
I’d try eating low carb if you’re not already doing that. LCHF and IF have been a near miracle for me. M 58. I lost 50 lbs with very little hunger, never tracking a single calorie, ate dinner to satiety every night, and 3 lbs of that was after I hit my final goal about 4 months ago. I mainly cut out sugar, wheat, corn meal and other processed garbage like chips, etc. with limited rice and potatoes. We all work differently but that worked for me.
What is your TDEE? How many calories are you putting in? Are you sure? You say you’re lifting… muscle weighs more than fat, what is your true body fat %. Dumping in the extra calories of alcohol? Body has to burn that before food… many possible variables here.
I bet you are still in much better shape than when you had started so don’t panic. First thing you should do is to journal your food intake: datetime, what you ate, quantity, and estimated calories. Don’t implement any changes.
After a a week, see if your journal reveals anything interesting. Too much carbs, too many calories, and just add minor changes. Continue logging and reevaluate in 2 weeks. Don’t panic, and don’t give up. Good luck.
Body set point is a real thing and why most people struggle to keep weight off. I had that experience and found that I needed to change WHAT I was eating because fasting alone stopped working. Fasting is an amazing tool, but it might not be enough to keep the weight off, which requires a reset of your body set point. That’s the tough part, and I don’t know that we have any perfect answers that work for everybody all the time.
What worked for me was eliminating all processed foods, grains, sugars, vegetable oils and reducing dairy and reducing alcohol. The struggle is real. I will allow myself to have some “junk” now and then, but right away it’s like I put on weight regardless of how much and how consistently I have fasted or how much I exercise. It’s like certain foods just trigger weight gain for me. So maybe something to consider.
You have to find a sustainable regimen for you. OMAD is too strict. You can’t practice OMAD in your everyday life. Try to switch to constant 8/16 window and reduce carb intake. After loosing all back you have to find a _sustainable_ weight maintenance eating habit.
