not the usual question about calories...

OP, the people that told you it comes down to amino acids are on point. 20 amino acids, of which are essential. Top of the list is Leucine followed isoleucine and valine for what we do.
Also keep in mind that you used 75g at 300 calories as an example but we don't actually get 300 calories worth of nutrition since we lose up to 30% through TEF.
Thanks (had to google TEF - I had heard of it, but didn't know the acronym. I had no idea it could be that high.)

It takes far more energy to turn protein into energy than carbs or fat. Your body would simply get rid of the excess protein just like excess vitamins or minerals. Normally, if you lift heavy, people tend to consume 1g of protein per pound of weight. Some heavy lifters even do 2g of protein per pound. Make sure to get a good blend of whey, whey isolate and casein protein.
Yeah.... No. Protein does not turn into carbs EVER. They are two different compounds.
Not ever? You sure?
Protein is broken down into amino acids via proteolysis. Amino acids can be broken down, the carbon backbones can be converted to acetyl-CoA and fed into the Krebs Cycle/Citric Acid Cycle/TCA Cycle. The intermediates and products of the Krebs Cycle can be used to build other compounds including carbohydrates.
I thought I was clear with what I meant but I guess not. I was talking about the MACROs people usually refer to. For example: a piece of steak is not going to magically turn into an apple in the body. Not the same as the multi-step break down cycles in the body (which most people don't even know the name of).
You sure you want to battle with science?
So you're talking about macros and don't mean protein and carbohydrate, you mean steak and apple. You also assume people are too ignorant to realize that an apple will not *poof* turn into a piece of steak in the body or anywhere else. OK.
I'm pretty sure I am big buddies with science. You, however, not so much.
Yeah... Okay. If it makes you feel better to put people down, feel free. I personally don't care.
And no, I do not expect people to know the difference between eating and Apple/steak and what their body does it multi-step processes. I qiluick glance through the first page or two of the forums shows that they clearly don't. When you try to contradict and use terms and processes the general population does not understand, you just create confusion. This is very clear when you read some of these threads.
Also, I would not be so quick to assume how "big buddy" someone is with science. This is most certainly a claim you will not win.0 -

(I've read many threads discussing this point...but that's not what I'm questioning)
the body needs a certain amount of proteins, fats, carbs (as well as other things) to function optimally, with individual's needs varying depending on their circumstances.
for example, even if you meet your carb and fat goals but go over in your protein goals, the body will store the additional calories (which came from the protein) as fat.
So my question is
(my apologies if some of my terminology is not correct. I'm not a scientist)
when we say the body 'needs protein' is it the entire protein molecule that the body needs, or is it somehow referring to the protein molecule without considering its calories.
consider the following
if your body uses 75g of protein, is it 'using' 300 calories (75 g protein@ 4 calories/gram) as well ? In which case if you had eaten those 300 calories as carbs (and not reached your daily protein needs of 75g) then they would not be used ?
or does the body somehow separate the 'protein-ness' from the calories.
I'm not talking about protein where you go over your daily needs. Also, I imagine that one day probably wouldn't make a difference, but I'm just using one day as an example to make my point.
any ideas ?
calories in > calories out leads to fat gain
not totally accurate...take fat out and put weight in.
and no your body does not store excess protein as fat if you are in a deficit..
and what the PP said...macros are for health and nutrition and body comp...
a calorie is a calorie no matter where it comes from.

"Calorie: noun
1. Also called kilogram calorie, kilocalorie, large calorie. a unit of heat, equal to one thousand calories, often used to express the heat output of an organism or the energy value of food Cal
2. The amount of a specific food capable of producing one thousand calories of energy."
Thus, birch may contain more calories when burned than pine. Just as fat has more calories than carbs. A Calorie is a measurement of energy rather than a measurement of nutrients. Macros are the measurement of basic nutrient breakdown. Calories area the measurement of how much food energy must be consumed to maintain your body at a specific level/weight. These are two different calculations that are related but separate.
ETA the definition of a "small calorie""
1. a unit of heat, equal to 4.1868 joules ( International Table calorie): formerly defined as the quantity of heat required to raise the temperature of 1 gram of water by 1°C under standard conditions.0 -

Hi! Let me see if I can provide some insight. A calorie is simply a unit of energy in the body, kind of like how volts is the unit of energy in a battery. When people talk about "macros" - carbohydrates, proteins, fats - they're talking about major sources of calories. Now, the body is amazing in that it can take whatever you give it and turn it in to whatever it needs. Lots of people get confused (or start arguments about [see above]) on this because they don't understand all the fascinating processes that can transform one compound into another.
Does ATP sound familiar from high school biology? ATP is the ultimate end goal of breaking down the macronutrients; it's the body's unit of energy, or what a calorie becomes. The different macros enter metabolic cycles (e.g. TCA/citric acid/krebs, glycolysis, etc.) and at different stages, but all end up as ATP. The type of macro they begin with determines how much ATP they produce, which is why certain foods yield more energy than others.
When you have too many calories - whether it's from fat, carbs, or protein - the body stores it as fat to use later when it thinks calories will be sparse. Fat is the storage vesicle of the body, which is good from an evolutionary standpoint, but bad for those of us that want to look good in our bikinis.
The body needs each and every macronutrient. Diets that restrict one of them are bad in the long run. For example, protein is broken into amino acids. Amino acids are the building blocks of proteins. If you don't eat protein, you won't build muscle. Fats are the backbones of many hormones in the body and is used by the brain when there's no glucose. Carbohydrates are readily available for rapid energy. Certain body tissues only use carbs as energy.
Hope this helped!

I did not communicate well. It activates for spam or abuse, but you can also use the report function that is also under the "flag".

But you didn't say that protein can't turn into carbs "except with a complex multi-step process." You said rather, that this will "not ever" happen. That expression means "without exception" which is why it was called out as untrue.0 -
