So you might think that but no. If your body is in shock the gear does one thing protects what you have . However it is far easier for your body to burn off muscle as fuel than it is to burn off fat as fuel . If you aren’t hitting your needs your body wants to protect its organs . So it goes what do I have to do to not die . And it does whatever it can to maintain.Yes I am 100% fixing all this up. But now is it not safe to think no matter what the diet is if it comes down to calories in calories out and if I’m frigging staving myself and still lifting heavy and maintaining muscle mass should I not still just drop the fat anyway?
I am also 5’10 same as you and I am also 15% bf. But I am also 226 lbs. when I diet down the fat peels off and I can eat easily over 3000 calories a day as long as I am eating good clean food and still lose fat. Your body needs muscle to function and it need those muscles fed properly. If your nutrition is dialed in it literally peels off.
A guy your size eating the right food will put on 15-20 lbs easy on a test only cycle and probably drop 3-5 -% bf at the same time if you dial in your nutrition
