I don't really believe that so much. I do think as you get older it is going to be harder to gain muscle weight, and maybe if you gain some, it may be a bit harder as you get older to take it off again. But I think as long as you stay consistent with things you wont ever have to worry.
SLEEP- Sleep is extremely important. Your body needs plenty to be functioning at its ultimate level. You should be getting at least 8 full hours every night. When you don't get enough sleep your body begins to stress. Therefore it is not going to burn as many calories, as well as it is going to crave different foods that give it a quick boost of energy like sugar. Making it harder to stay on a healthy meal plan.
Also as you sleep believe it or not you are burning calories. Your actually burning a lot! For every hour of sleep your burning approximately 50-55 calories. So in eight hours you would burn up to 440 calories!
