I know the body has a limit on how quickly it can build muscle, set by hormones, genetics, how much muscle you have built etc Eating and training more won't make your body construct muscle any faster, you'll just get fatter.
But what about fat loss ?
Does the body put a limit on how fast it can consume its fat stores for energy ?
If there is a limit and what is it controlled by ?
What determines when the body starts breaking down muscle ? Some say more than 2lb per week and your probably losing muscle but you cant put everyone in one box like that.
I have been cutting hard with about 9000cal/week deficit the past month and have lost about 12lb (from 14%bf so no in the obese category) and I doubt much of it came from muscle as I haven't lost any strength or reps.
I know nutrient partitioning and insulin sensitivity comes into play, but I doubt I have those advantages coming from a family where my dad and grandad have type 2 diabetes and having a set point BF% around 13-14%.
I would love to know the science of it all.
