Disagree on both, how you eat isn’t a “lifestyle”, it’s just food. A diet is whatever you eat, regardless of whether it’s a structured WOE or not. I know people like to say that, but to me that’s walking the line of vegans making their WOE their religion, I just can’t do it. Rant over.
Honestly, people over play the “changes happening thing” but since you’re lifting (good!) it’s true the scale will be slower to react, but you can’t put on muscle as fast as you lose fat, so you’re right, it should still be dropping, just slower. True Recomposition is EXTREMELY hard to do!
YES! When your appetite leads you into failure. If that less than 1000cals is normal for you, that’s exactly where you are right now. Don’t expect results if you’re not paying attention to what you’re eating, you’re going to fail, sorry. Very few people can intuitively eat correctly. It’s a great dream, but there’s literally been studies to prove how terrible the majority is at doing it.
Not eating is a stress to the body, eating <1000 is a stress to that body. I also wouldn’t expect near any results with muscle gain at 54g of protein a day, I honestly wouldn’t expect somebody to maintain their current muscle mass at that low of a protein intake. OMAD is not a friend of muscle gain. You’re lifting, you need fuel and to remain in a positive nitrogen balance as much as possible to fuel growth, recovery, and all your normal protein needs.
Not sure what your lifting program looks like, but the fact you’re able to eat that little while actively lifting is a very good indicator your metabolism is on the downswing. Lifting should be making you hungrier, which would be very normal.
I’d go by the go-to of 1g/lb bodyweight on protein and make sure you get it in, prioritize it. Get your carbs that you eat in, and on the fat, that one you may have to play with. Many of us have found we gotta limit it. I can’t lose fat if my fat crosses the 100g mark, but ideally 60-80g. Your body has no reason to burn stored fuel when you’re giving it plenty. If that doesn’t get you to your calorie goal, I’d just add more protein if possible, you’re not going to get fat from protein, sometimes it can be tricky.
If you have trouble figuring out macros that work for your goals you can either start figuring it out weekly until you hit the sweet spot by paying attention to your results and tweaking slowly, if you don’t know how to do the math on that I can write out what I’ve done and what most people do to figure it out and attempt to compensate for the fluxuations, or you can cheat with an app that does it all for you, downside to that it’s not free, but it’s awesome and worth it to make it effortless.
