How Fast can you gain a pound of bodyfat?

[Atp/Cp]

I can't find anything on this online or here.

So how fast can you gain a pound of bodyfat(not muscle or water weight)?

[ceilos456]

im guessin anything over 2 pounds in 1 week, i knwo the optimum amount of weight to gain while bulking is 1-2 pounds per week

[AphtaLyfe]

You could probably gain 1 pound of bodyfat in a day.

1000calories a meal, eat a meal every 3 hours. Eat 6 meals.

Don't lift. Have your maintainence calories be 2500.

I'd expect you would put on that pound if you exceeded your caloric maintenance needs by the caloric value of a pound of fat.

So I guess if you could exceed your maintenance calories by 3500 in a single day, you could gain a pound in bodyfat.

I might be wrong though.

Why are you asking this...

Why are you asking this...

Because he's curious?

So how fast can you gain a pound of bodyfat?

On a good (bad) day....I'd give myself about....40 minutes.

The reason why I mentioned 6 meals with 1000 calories per meal is because your body can't handle any more than a certain amount of calories in 1 sitting. Your body can only process food so fast, and your intestines can only move food so slow before expelling a considerable amount of un-fully digested food.

I have yet to see a scientific research that shows this.

Yeah, this isn't true. Eat 2 big macs and an order of supersize fries (3000 kcal) in one sitting and I promise you your body will utilize practically every single calorie, and hate you for it.

well ofcourse thats true, but we dont know actual numbers for that so its pointless to say. Id bet thats its a LOT more than the 1000 every few hours that you suggest though. If I ate 5000 calories in the next hour, I dont think it would neccessarily experience a less complete digestion than 10 x 500 meals several hours apart (even over two days)

I said 1000 calories x 6 meals just as a example. I'm sure people can process more, and some maybe even less. I just used that as a good way to make sure someone gained 1 lb of fat.

There is a study for how much protein the human body can absorb in 1 sitting. Its something like 100g for a 175lb person. That's 4000calories in protein as a maximum. I'm assuming the protein can't be absorbed further because by the time the bulk reaches the end of the GI tract it is expelled before further nutrient utilization.

I'm also assuming since the protein reaches the end of the GI tract and is expelled that all other nutrients will have difficulty being absorbed simultaneously.

There's no study out there that sat 15 people down and made them eat 10000calories, 9000, 8000, 7000...etc... and calculated their maximum calorie intake.

I've eaten 13 pieces including the crust of pizza hut pizza + 2 cinnamin rolls + a salad with thousand island dressing. That's roughly 4000 calories + my normal lunch, breakfast, protein shakes, PWO banana.

I promise you I didn't gain 1 pound of fat.
After gaining the initial water weight and my normal monday weigh in. I was 3lbs over my normal. By the end of the week I was back at my normal friday weight. With no out of the ordinary dieting.

Protein not utilized as amino acid building blocks = converted to glucose and oxidized for energy or stored as fat. Nothing is wasted. The stomach can expand to hold up to 6 L of volume. That's a lot of food.


And there are metabolic tricks which seem to disobey the calories in vs. calories out. Mainly the body can buffer a large amount of carbohydrates if muscle glycogen is depleted (through low calorie, low carbs, high volume depletion workouts) - allowing you to eat way over maintenance but still not gain fat. This does not mean that the calories are simply not absorbed by the body. They are just used to synthesize glycogen. And yes, on the UD 2 diet, I was able to ingest 1200 grams of carbs in a day to a grand total of 7000+ kcal (while my maintenance is around 2700 kcal) with zero fat gain. But I was thoroughly depleted before doing so.

Agreed (My glycogen was very depleted from that week's cut), but that wasen't the point I was trying to make.

I guess when you said "Your body will hate you for it" I thought you ment it would make me gain the 1lb of fat that the OP was asking about.

My mistake if that's not what you ment.

Also just because the stomach can expand to hold X amount of food. Does not mean X amount of food will be completely digested. If you really want to try to prove me wrong... drink a liter of olive oil and you'll go to the bathroom about 30min later and expell almost nothing but oil. To me that represents the body not being able to absorb the oil quickly enough before it gets excreted.
