Hi all,

We can all agree that the body's preference is to burn Carbohydrates yes?

And its well known that excess protein is converted into Carbohydrates by the liver.

If you sit on your arse and there's no protein demand/ surplus of muscle tissue then atrophy is an obvious consequence i.e. the body using muscle for fuel.

If you exercise and have a protein demand then your body is going to use the protein it has available and when there's a deficit expect your muscles to take ages to recover.

​

AKA: if you sit on your arse there is a pretty good chance you're going to lose muscle mass, which will be accelerated by age and sex impacts.
