Why count protein as calories?

COS YOU FUCKING ATE IT

I will never understand why people think comments like this are helpful. Do you really think that's as simple as this topic is? Do you really think protein as calories works exactly the same as carbs/fat?

Thanks to all you other folks who tried to make me feel stupid "of course you count it". If you don't have the curiosity to better your understanding of basic body chemistry, don't pretend like you already know, cuz you clearly don't.

Carbs and fat don't work exactly as each ther either so why count them if that's the logic being used?

Look at it this way. If you sat on the couch all day and drank 10000 calories of whey protein shakes a day you'd still get fat. I don't understand what your point is.You can store calories as fat no matter what the source

Because, as I understand, fat and carbs are much, much more likely to be used for calories/stored as fat. Maybe that's wrong I guess.

You CAN store protein as fat, yes, not my inquiry really. Is more "is it really likely, in large amounts, under normal circumstances"

protein is used for calories. Carbs are almost never stored as fat.

You cannot directly store protein as fat.

Well, if it was NOTHING but protein, you might end up in "rabbit starvation" (if such a thing exists for really reals) but since it would definitely have carbs and fats along with it you would, you say, avoid the mythic and epic death by rabbit starvation, and process along nicely into "fatitute" due to overall caloric intake.

Protein counts because you eat other things....

Trying to eat *only* protein leads to death when successful.

None of it is magic.

A wise man once said, "if human bodies somehow didn't use all the excess calories we feed them, fat people would be so rare we would have them on museum display." (paraphrased)

As to why you need a surplus to gain, the laws of thermodynamics govern that fairly well.

Same reason your car won't move forward without consuming enough fuel to produce energy in excess of that required to overcome inertia and perform work on mass.

If you have an alternate energy source (like fat guys do) you can gain while in a small consumption deficit because you are pulling the rest of the energy from fat stores (there are limits here).

For anyone who cares.

Protein= 4 calories per gram
Carbohydrates= 4 calories per gram
Fats/lipids= 9 calories per gram


So essentially if you cut out carbs and replace it with proteins your caloric intake will not change.

What about last night when I ate a whole block of chocolate right before bed? ><

I am told that this is no longer an appropriate way to refer to performing cunnilingus on a black girl...

Quoted because this made me laugh

Enjoy it and lift big the next day lol.

This is too funny to ignore lolol

Well, there is the definition issue of a calorie - it goes back to actually incinerating the food and measuring the heat content. Which doesn't always make sense, just because it burns doesn't mean that it gives the body any energy.

Case in point being cellulose, aka fibers, which have calories, but they're indigestible.

So there ought to be some kind of bioavailability modifier applied to calories.

Not my area, but I have wondered about the validity of calories - seems like an apples and oranges thing if you think about the definition. And we know that 100 calories of HFCS isn't the same (in the body) as 100 calories of cold pressed olive oil.

Fiber is partially digested by the body. Current research suggests fiber gives roughly 2cal/g of energy.

You are comparing a carbohydrate source with a fat source so you're right, they are not the same. Compare a fat source with a fat source or a carb source with another carb source and they are, for the most part, the same.

Carbohydrate metabolism and de novo lipogenesis in human obesity.

Acheson KJ, Schutz Y, Bessard T, Flatt JP, Jéquier E.
Respiratory exchange was measured during 14 consecutive hours in six lean and six obese individuals after ingestion of 500 g of dextrin maltose to investigate and compare their capacity for net de novo lipogenesis. After ingestion of the carbohydrate load, metabolic rates rose similarly in both groups but fell earlier and more rapidly in the obese. RQs also rose rapidly and remained in the range of 0.95 to 1.00 for approximately 8 h in both groups. During this time, RQ exceeded 1.00 for only short periods of time with the result that 4 +/- 1 g and 5 +/- 3 g (NS) of fat were synthesized via de novo lipogenesis in excess of concomitant fat oxidation in the lean and obese subjects, respectively. Results demonstrate that net de novo lipid synthesis from an unusually large carbohydrate load is not greater in obese than in lean individuals.

Was this a typo?

Your later post "Carbohydrate metabolism and de novo lipogenesis in human obesity." says the opposite.

Carb intake above a certain amount = fat deposit growth. That's how the body works, no?

One of the basic laws of thermodynamics is that energy cannot be destroyed. This is why this discussion is entirely retarded.

Eat over your maintenance and it will be stored. No amount of mental masturbation will change that.

Abstract

The enzymatic pathway for converting dietary carbohydrate (CHO) into fat, or de novo lipogenesis (DNL), is present in humans, whereas the capacity to convert fats into CHO does not exist. Here, the quantitative importance of DNL in humans is reviewed, focusing on the response to increased intake of dietary CHO. Eucaloric replacement of dietary fat by CHO does not induce hepatic DNL to any substantial degree. Similarly, addition of CHO to a mixed diet does not increase hepatic DNL to quantitatively important levels, as long as CHO energy intake remains less than total energy expenditure (TEE). Instead, dietary CHO replaces fat in the whole-body fuel mixture, even in the post-absorptive state. Body fat is thereby accrued, but the pathway of DNL is not traversed; instead, a coordinated set of metabolic adaptations, including resistance of hepatic glucose production to suppression by insulin, occurs that allows CHO oxidation to increase and match CHO intake. Only when CHO energy intake exceeds TEE does DNL in liver or adipose tissue contribute significantly to the whole-body energy economy.

It is concluded that DNL is not the pathway of first resort for added dietary CHO, in humans. Under most dietary conditions, the two major macronutrient energy sources (CHO and fat) are therefore not interconvertible currencies; CHO and fat have independent, though interacting, economies and independent regulation. The metabolic mechanisms and physiologic implications of the functional block between CHO and fat in humans are discussed, but require further investigation.

The mental masturbation is bc many people are afraid of eating carbs specifically for the reason that a gram too many will cause them to get fat or that excess carbs are stored as fat causing them to micromanage their carb intake.

In the real world this is not likely to happen, especially in this population demographic. As you know, carbs help boost glycolotic performance more so than dietary fats do so this discussion is pertinent IMO.
