Diet-wise, what seems to work best for you wrt macros? I always thought keto worked best for me, but when I factor in performance, keto is a no-go.
My recent diet just focused on cals and getting enough carbs for intense workouts, and it has surpassed the keto diets by far.
Keto doesn't work for me either, but it may be that I can't handle it mentally and don't really find the point in it if I can cut fine without it. Either I crack and eat a ton of brown rice after making a bunch at one time, or my workouts feel like I'm always running on empty. Personally, the way I find that works best for me is just a consistant clean diet but strict, trying to get as close to a calorie amount as possible. Consistant weight training and cardio as well. Macronutrient ratio doesn't seem to have a big impact, although I generally shoot for 40/40/20.
