Since people with high body fat don’t need fat, they can skip it which will help create a deficit through “dropping calories”. If they don’t eat fat, they can use their own instead which is the point of fat loss. They can eat carbs, but then fat burning stops and insulin will create minor changes that we can sense.

From there you gauge your appetite which is a result of your hunger hormones. Leptin and Ghrelin.

Note that this recommendation is for total weekly volume, which means it would need to be divided up based on how many times you’re training each muscle group per week. So, for example, someone training everything twice per week would do 30-70 reps for each bigger muscle group in each of those workouts, and 15-35 reps for each smaller muscle group in each of those workouts.
