I imagine this fluctuates minute by minute and hour by hour depending on intake and activity...and the size of the overall surplus.

not something I wouldn't spend anytime worrying about.

I was looking for something more substantial than the whims of your imagination

well I would be interested if anyone could give anything more concrete.

Seems to be a bit of a 'how long is a piece of string' question as there are so many variables.

The fact that your 'maintenance' is going to be slightly different every single day dependent on that days activity being the main issue I can't see how anyone could ever put a definitive number on it.

But WTFDIK.

100%.

My guess is every calorie, regardless of macro, not needed for normal functions, repairing/growing muscle, replenishing glycogen stores will be stored as fat.

My smartass answer. ^


I have seen some guys, with very small surpluses, gain very little fat with their new muscle. It is really going to come down to the size of the surplus. The farther from maintenance the larger the percentage of fat gain. There is also the persons ability to grow muscle that will effect the outcome. Some young male might be able to add over a pound of new muscle in a month. If he could manage his calories to only gain that one pound he might add very little fat. An older guy or veteran lifter might not be able to synthesis that much muscle so his ratio might be more fat even if he only added the same one pound.

Managing calories that accurately is ridiculously hard IMO. My daily fluctuation in weight can be around 5lbs. Almost impossible to see a 1 pound gain over an entire month. That is why people shoot for a 1:1 or more ratio. Making sure they have enough calories to maximize muscle gain potential without gaining to much fat.

Looking at table 1 - At an intake of ~1500 kcal extra the 1.48 kg for carbs over 14 days is 814 kcal/d stored, for fat 1.52 kg over 14 days is 836 kcal/d stored

Why do you think it is 100%? I would like to read more

My answer was sort of a joke but that study is pretty Interesting. I wonder where that extra percentage went in that study. Since energy is always conserved, if we believe in the law of conservation of energy, it must be something like the thermal effect of that macro or eliminated unused.

I thought you were talking about the ratio of muscle to fat gain in a surplus.

I have no idea as to the answer, but I don't think the posted studies would necessarily be applicable to someone engaging in a progressively demanding resistance training program.

why

I'm assuming that the presence of adequate training stimulus would have an effect on nutrient partitioning. Take a population of people at a given energy surplus who are not lifting and compare them to a population of people on a progressively demanding resistance training program and I would expect to see differences in the proportions of fat vs lbm gains.

*sigh* stop being silly

I'm not, I've not seen any data to support your claims and I would like to see it

Tough *kitten*

So its possible to store 100% of excess calories as fat?

From that article. Might want to read it.

You haven't lifted in couple days, nothing to repair.
You spent the day sitting at work.
You just had a big carb meal and topped off all glucose stores.
Your insulin is still high.
You plan on sitting on rear for 4-6 hrs marathon watching Breaking Bad and then sleep.
You devour a bunch of high carb/fat food.

At that point sounds like all that excess will be stored as fat.

I'd suggest a good 2 week experiment, if you are up to it. Might have to watch reruns of perhaps Lost too though.
