The energy cost of muscle-protein synthesis

The current/active thread related to 'main-gaining' sparked in me a familiar - but somewhat unique - course of thought which im not entirely sure has been discussed here before, so I'm curious what people have to say about it.

When we discuss a calorie surplus in the interest of gaining weight for 'bulking' of any kind, typically we are referring to a rate of fat gain; 3500 calories of excess energy results in ~1lb of fat gain, the standard goes.

So for example, if someone goes on a 250 calories / day surplus, they gain roughly .5lb of fat in a week, or about 26lb in a year, etc.

Now what got me scratching my head is related to someone's capacity for muscle gain specifically, and how that contributes to the net total weight gain over a period of time... because if someone gains 26lb of fat in their first year of lifting while in a 250 calorie surplus... that's only the fat mass... what about the muscle?

It's been speculated that a newbie might even gain 20lb maximum of muscle tissue in there first year if they do everything right, are maybe taller, etc...

So if that's the case, would that 250 calorie a day surplus result in a 46lb weight gain in a year since it would be 26lb of fat and 20lb of muscle?

If so, then that person wouldn't even be able to track weight gain to that goal rate, because on the scale it would look like they were gaining almost at TWICE the desired rate...


Never thought about that before but, anyone have thoughts on that? I'm just curious if, especially when rapid lean tissue gain is expected, we ought to be more generous with the rate of gain because perhaps a 250 calorie a day surplus might result in something like gaining .8-1lb a week with something like 40% of that being muscle... as opposed to seeing that weight gain and assuming it's 'too fast'.
