Hey, I've always wondered actually - let's say you added a good amount of muscle mass (15 lbs. LBM) and cut down and all, and then you happened to go on vacation and miss a couple days of heavy eating (let's just assume it was inevitable). Well, how long would it take to actually start losing muscle mass.
I assume this depends on how much protein you're having, and if you're training or not.
Let's say not training, and getting about half your bodyweight in protein (for this example let's say 100 lbs. - therefore the individual is 200). Would it take a descent amount of time at least? I ask this because it would suck to build such mass, and then screw it up so easily if you accidentally miss a day.
I know some might say "don't miss a day" then (of eating or training, whichever) but I'm just thinking ahead and at one of the worse scenarios that could occur.
And also, if you happen to lose that muscle mass over whatever period (some of it, at least) - is it easier to put back on than it was to achieve initially?
