Look, you should see bodybuilders diet, they know what they are doing and that's important, prep your meals, start carb cycling, keto diet is when you have like 11℅ bf and you want that one digit bf. Exercise like 4 or 5 times a week if you have time, make a plan for your exercises. Your day should have 4/5 meals. 1st one is breakfast. You'll need to know yourself I like proteins and fats in that one, maybe 4 eggs and some nice salad with olive oil(you need to have salad in every meal) after that I like to have 2/3 more meals that are meat/fish and complex carbs(very important they are rice, potatos and sweet potatos) and those meals are before and after workout and one is to not be hungry and to have macronutrients in your diet, last one for me is dinner and then I go to sleep, that one is proteins and fats, some nuts, some low fat and low carb cheese or maybe more meat or some eggs or fish, it's all good. Once you get in that mindset it will be fun and you will almost never be hungry, also it helps with hangovers for me, well atleast for alcohol and mdma ones, I also smoke weed like 4 times a week but that's another story. I was fat from 9 to 15 y/o and from that point a I live really healthy and I am kinda buffy and lean, not too much because I don't want to compete also there is too much work for sick physique. Make your schedule and stick to it, you need eating, exercising and sleeping pattern. If you want help you can pm me your pics and your details, if you want supplements do it bodybuilding way, omega 3 fat acids, some whey, some mineral vitamin supplements, some coffein if that's your thing, working out have some of it own high. Cheers and good luck you can do it and I belive in you even if I don't know your full story
