What makes you think the body will dump calories after X amount? It will process everything you consume, while some will get lost from fiber intake like a small amount, you can't binge and expect most of the calories above maintenance to "disappear".

Riiiiiight.... So if i were to drink 5 litres of olive oil in one day, roughly 42,000 calories subtract 3000 calories for maintenance leaving an excess of 39,000 calories my body will instantly covert that to 5kg's of stored body fat in one day will it?

I really dont think u would be able to consume 42,000 cals of anything in one day lol..maybe if u slowly work up to eating that much and become morbidly obese over time...but if just one day out of the blue u decide to do that..i dont think ur body would be able to handle it...u wouldnt process most of the cals cause you would be throwing it all up

now on a "normal" binge lol....id say your bodies ability to store all those cals as fat depends on how far from your BF set point you are and how long you drag out that binge...if u are coming off a show for example and are extremly lean..<5% BF...then yeah...your body is gonna take as much of those cals as it can and store it as muscle glycogen/water/fat...if you are already at your set point or above it....i would assume the amount of actual fat your body would put on would be less.

but what do i know...im just really going off shiit that ive read...even if u are at your set point and binge uncontrollably..u may still use as much of the cals above maintenance as it can and store it..again as muscle/muscle glycogen/water/fat

You have to remember that digestion v's metabolism v's storage are VERY different things in the body...

And one doesn't necessarily reflect the others.

Digestion/ absorption of different foodss via the digestive tract is not a process that is the same for everything. No one can give a certain figure on it, and it is certainly not 'calories above maintenance' that determine whether or not your body 'can absorb' food in the digestive tract.

In fact - The average human digestive tract can absorb a STACK more calories than 'maintenance' over a given day. And even laxatives (which speed digestion) will not cause *that much* calorie loss. http://www.annals.org/content/99/1/14.abstract

How much any one individual can absorb during one sitting / day is a function of things including:
- macronutrient type
- fiber content
- digestibility of the food
- total load/ volume of the meal and the SPEED at which you eat the food
- your individual intestinal tract and secretary / expansion capacity
- the rate-limiting step in the path by which the nutrient is degraded/ absorbed (eg: does it require bile? Does it require pancreatic enzymes? What mucosal enzymes are involved?). etc etc

So - some macronutrients don't require as much processing in order for digestion/ absorption to occur.

Higher fiber = less absorption.

Certain foods have inherently higher digestibility's than others - thus, you'll be able to absorb some foods better than others when eating a stack of them.

A VERY high total calorie load can cause gastric dumping and malabsorption diarrhoea - which will speed transit and decrease calorie absorption.

BUT, on the other hand, a high calorie load will / can also delay gastric emptying - leading to a slower transit time, which will increase calorie uptake.

Basically - 'no one can say'.

I would think that the consumption of simple sugars has a very high absorption rate, so most of those should always count but I could be wrong. If you'd like to eat some high fat food's sometimes and reduce fat absorption, look into taking some Alli.

This article (http://ajpregu.physiology.org/cgi/content/full/275/1/R300) states that intestinal capacity for absorption of energy ranges from 0.66-0.94 kcal/ meter/ min.....
http://ajpregu.physiology.org/cgi/content-nw/full/275/1/R300/T3

There is also this article (http://ajpgi.physiology.org/cgi/content/abstract/261/4/G608) - that indicates a safety margin of ~ 220-300%.

And let's assume your gut absorbed everything. Looking at overfeeding studies >>>
Over 60 days, using the Guru Walla overfeeding protocol (http://www.ajcn.org/cgi/reprint/56/3/483?ijkey=34f341ac6b98e15b16790528a7eb6b97b7ec11d1 ), eating about 6500 ish cal/ day, you can gain about 17kg [37-38#], 65-70% of which was fat. Which averages out to be ~ 280g weight/ day (half a pound).

And in another paper re glucose overfeeding - it can be seen that After glycogen reaches capacity (http://www.ajcn.org/cgi/content/abstract/48/2/240) eating only 475g carbs/ day will cause a storage of 150g fat/ day.

Then increasing carb intake further - This study showing fat synthesis during carb overfeeding (http://www.ajcn.org/cgi/reprint/65/6/1774) showed that the body easily absorbed very high intakes from NG - and that intakes of 2.5 x energy expenditure can result in a total fat synthesis UP TO 2243 mg/kg/min after four days. Net weight gain - about 2kg [~ 4.5 #] over the 4 day study.... and to cut and paste:
.... After 4 d of high-carbohydrate feeding, net fat synthesis at the wholebody
level was “2250 mg - kg’ - d’ (ie, “170 g/d). Thus, adaptation to a hyperenergetic carbohydrate diet involved a substantial increase in de novo lipid biosynthetic activity.
However, at this time the liver produced ı40 mg fat - kg ı - d ‘ (ie, “ı3 g/d). Although this value was ı50-fold greater than the basal rate, hepatic de novo synthesis of fat only
accounted for 2% of whole-body fat synthesis after 4 d of hyperenergetic carbohydrate feeding. Most likely, the adipose tissue had adapted to the high carbohydrate load by synthesizing 167 g fat/d....

Lastly - this overfeeding study comparing fats and carbs at 50% over maintenance (http://www.ajcn.org/cgi/content/abstract/62/1/19) states that in carb overfeeding you can get 75-85% of excess consumed - stored. And Fat results in a 90-95% storage of the excess. So if you assume a maintenance of, say, 3000 cals....
+ 50% = 4500 cals
Assuming your glycogen stores were FULL.... If that extra 1500 cals came from carbs - you'd store ~ 1200 cals worth (about 130g worth of fat).
If that extra 1500 cals came from fat - you'd store ~ 150g worth of fat...

Thus: If you increased intake to match intestinal absorption capacity - you'd get fat quickly.

Obviously it will be different for everybody but there has to be a point when you consume so many calories your body cant process them so they pass straight through doesn't there..

So how many calories above "maintenance" is it likely your body will simply waste them?

Ive actually experimented with this and its not much. I would have these buffets i go to where i ate abou 5k-6k calories (ya i know a lot) on every sunday. Well at 1st i wasnt gaining a pound from it, i would diet strictly 6/7 days of the week and i was actually leaning out for a little bit.

But my body starting adapting, it got better at storing the more of it as fat each time =(. Id say thats something a lot of people arent aware of that i found out in 1st hand experience.

I had to cut out the buffets because it eventually stalled my progress and now im doing great.

Honestly my guess would be your body cant add on more then 1/2 pound of fat per day, but its so subjective for each person and as emma said it depends on so many things that its impossible to really even know a ballpark figure without more details.

I mean people dont get fat in a day, or a week, its a long term thing kinda.

Your body will eventually start "reject" things that are in excess... like emma said, vomiting, diarrhea, so on. And things like carbs are absorbed more easily because our bodies are programed to survive. Carbs are easy to turn to fat, and fat is a good long term energy source. Long term energy means you can go longer without starving to death

Your body can handle a lot, but it kind of depends on the health of your digestive system on what it can absorb.

Sorry but thats wrong bro, De novo lipogenesis doesn't happen that easily, it takes massive carb overfeeding for it to happen. Carbs indirectly make you fat when taken in excess because the body converts the dietary fat consumed to fat. Carbs themselves rarely get turned into fat.

It's water weight, the only way you gain any weight that's fat is if you're eating over your maintenance. Massive water retention is quite common after eating carbs when you've been on a low-carb diet for an extended period.

As far as gaining weight really fast when you up the carbs, that's because the dietary fat consumed is being shuttled even faster into fat cells because the body doesn't need it. It's not the actual carbs being converted into bodyfat.

Cheers, this paragraph answered my question and was pretty much what I had assumed..

Do you have a link to any research on the levels of glycogen stores muscles are cappable of?

Carbohydrate
For carbohydrate, the body’s stores are relatively close to the daily intake. A normal non-carb loaded person may store 300-400 grams of muscle glycogen, another 50 or so of liver glyogen and 10 or so in the bloodstream as free glucose. So let’s say 350-450 grams of carbohydrate as a rough average. On a relatively normal diet of 2700 calories, if a person eats the ‘recommended’ 60% carbs, that’s 400 grams. So about the amount that’s stored in the body already.

For this reason, the body is extremely good at modulating carbohydrate oxidation to carbohydrate intake. Eat more carbs and you burn more carbs (you also store more glycogen); eat less carbs and you burn less carbs (and glycogen levels drop). This occurs for a variety of reasons including changing insulin levels (fructose, for example, since it doesn’t raise insulin, doesn’t increase carbohydrate oxidation) and simple substrate availability. And, as it turns out, fat oxidation is basically inversely related to carbohydrate oxidation.

So when you eat more carbs, you burn more carbs and burn less fat; eat less carbs and you burn less carbs and burn more fat. And don’t jump to the immediate conclusion that lowcarb diets are therefore superior for fat loss because lowcarb diets are also higher in fat intake (generally speaking). You’re burning more fat, but you’re also eating more. But that’s a topic that I’ve not only addressed previously on the site but may look at in more detail in a future article with this piece as background.

Your body can handle 10 times a normal diet- around 20,000 calories. There's plenty of excess capacity for digestion in the small intestine, so you can go way overboard and absorb the majority. Pretty hard to get up to the limit ;)

That's very wrong. Very wrong. If you're taking in even a few hundred more carbohydrates than you're burning, they're being stored as fat. Glucose is easily converted to acetyl CoA which is easily synthesized into fatty acids. Pretty simple. All about in vs. out.

No not really.... I clearly said it takes massive carb overfeeding before de novo lipogenesis occurs. Which means you have to be completely maxed out in glycogen stores everywhere in your body, plus consume a couple hundred more carbs before your body begins to convert a carb into bodyfat. This ain't as simple as you think, assuming you're already eating this high amount of carbs means at this point your body has completely stopped utilizing dietary fats which is why they are completely shuttled into bodyfat. As far as the carbs go, the more glucose in your body the more you utilize the carbs as energy so they are being used as energy even faster. Which means the carbs are even more likely to not reach the point of overfeeding it takes before your body converts them into bodyfat. If you think that is so simple then you need to start reading some more. Also you clearly just said "If you're taking in even a few HUNDRED more carbs than you're burning, they're being stored as fat." Thanks for proving my point....

That study just confirmed that eating carbs does increase fat storage... did you even read it? Or are you just not smart enough to understand the information?

Lyle did a follow up article on this. Increased carb consumption increases the dietary fat to body fat storage because your body goes after carbs first for fuel purposes. Carbs themselves rarely convert into body fat except in cases where your dietary fat as a ratio of total calories goes under 10% (200 calories in fat for a 2,000 calorie diet) or when you are mass loading carbs daily. This is probably not the case for any of us.

So I'm sorry in this case thegymbum is flat out wrong and ncummings86 isn't understanding the mechanisms which lead to fat storage. You will gain fat with extra carb intake but it isn't a direct route. It's akin to having 2 gas tanks where 1 tank is primary use. The 2nd tank (dietary fat) is either stored (body fat) or burned when tank 1 empties out (less the normal body processes that immediately require dietary fat blah blah).

No, I understand that concept... But the bottom line is that eating carbs do increase fat storage. SOME de novo lipogenesis DOES take place, whether it is a lot or a little. And the carbs are a preferred energy source before fat, keeping your body from burning fat. Leaving the fat that is there, retaining the extra dietary fat, and adding the little fat that IS generated through de novo lipogenesis.

The point is that carbs in excess cause fat gains (like I have said all along). They CAN turn to fat. And they DO prevent fat loss. Some carbs aren't an issue, as long as you can burn the energy off, enough for your body to use the fat as well.

PLEASE someone post the link to this Lyle guys study. Apparently he has some ground breaking theory that proves every other study ever done on the subject wrong (all of which leading to the same basic conclusion). While still backing the same thing that every other study has said.

I do disagree that ONLY carbs make you fat, but all I am trying to get through is that carbs do easily turn to fat. Come on guy, I don't believe things someone says just because they have a PHD. But I also don't believe anything I read that says it has scientific studies. For every scientific study that proves something, there is usually another one to prove it wrong.

I do know that when I consume a lot of carbs, I start to gain weight really fast. And its not a good kind of weight.

These are the posts that started this. Now you are making a completely different argument. Your initial statements, all three, state specifically "carbs easily turn to fat." Your new, modified statement is partially correct (carbs in excess cause fat gains) and was being argued because we rightfully were applying this statement to what I quoted above. So don't go acting like you "have been saying this all along" when it flat out is not the case.

I guess that guy doesn't know that excess protein causes fat gain as well? Yep, you read that right, dietary protein causes an insulin release that blunts fat oxidation, just like your cursed carbs do. Like I already said, go back to the Keto forum where you belong.
Its possible for protein to be converted to fat, but its rare.

The only time its possible, is your overfeeding in protein only!@

Dietary Fat, than crabs get prioritize by the body first.

Don't forget that your body regulates it's metabolism around a homeostasis point. If you occasionally eat a lot for one meal you body with heat up and try to burn off the extra cals. If you under eat one meal your body may cool down a little and try to save some energy. This is the main reason that most people don't change in weight from year to year and never count cals or macros. The body is very smart and if you learn to listen and watch how it reacts you can use this to have you cheats when you want and not worry about getting too fat or too lean.
