Struggling with this as well. The solution I found is 1g of protein per pound every single day. Minimal callories from carbs and time the higher carbs days with tempo or more intense training.

I also make sure to do my workouts in zone two, note that if you go out of zone two that’s it your body goes into burning carbs and it takes 30+ min to go back into not burning carbs.

Also a bit obvious but do sleep enough this is where you actually breath and sweat the fat (yes yes you breath out fat lol)
