A while ago on a paleo blog, I remember reading about a former marine's experience (but I can't find it!). He says he gained lots of muscle mass while in the military, where the caloric intake isn't as high as trainers often recommend for putting on mass. He contrasts this with his training experience before joining the military, in which his muscle mass gains were limited, despite eating well and eating lots.
Any thoughts about this? Maybe growth hormone is involved? Sorry if this is a strange question. It's been lurking in my mind for a while now.
If you have excess body fat, which is common among folks at the time they join the military, a calorie deficit will make you gain muscle and lose fat at the same time:
The reason is that the extra calories needed to spare muscle tissue are coming from the stored fat. If your body fat levels are fairly low, you will need a calorie surplus to gain muscle.
In trying to figure the same thing, everyone says my 5x5 split will halt in progress if I don't eat more but Charles poliquins view is different.
I know some people are different, but when I IF I barely manage 1800 cals a day, and I'm a 300lb former nationally-ranked strongman competitor.
I don't seem to lose any muscle when I do this. Lately, I've been doing this for 2-3 days a week (just bored with eating all day, truly).
If I eat all day, I'll easily make it to mid 2000's per day, so there is a fairly significant difference in my calories in on fasted vs. normal days.
If you are trying to increase your weight, you must consume more calories then you burn. (laws of thermodynamics)
It is possible to lose fat and build muscle at the same time as novices do it all the time.
