Whatever you do, make it minor and easy. For example, you could try playing around with various proportions of food to see what makes you feel the best, most energetic, and what seems to allow you to start losing some of the extra fluff without feeling hungry. For most that’s going to be more sugar and less fat unless you get to the truly low-carb point, which is going to suck whether you lose weight or not.
Or you could try eating small meals frequently vs. eating huge feasts only when you’ve built up ravenous hunger. Sounds like the latter might be a better place for you now. All disinterested in food and what not.
And of course there’s exercise. A few calisthenics and simple exercises at home with progress in mind can go a long way if you are patient enough to see that added strength and fitness kick in visually.
