You think fresh produce is cheaper than junk food. You were off by 350%.
By cal/dollar, which I explained is a stupid fucking metric. Chug a bottle of canola oil.

You don't know what proteins are and thought that the human body didn't produce them.
You don't produce them. You eat protein. Break them down into amino acids. You can even turn some amino acids into other amino acids but you don't produce any proteins from other macro nutrients.

You don't know what amino acids are.
I do. I did before because I'm not an idiot. I also know free amino acids don't occur in appreciable amounts in foods.

You think BCAA powder is an supplement for all amino acids, when it only contains three.
I do not. That was an example of an amino acid supplement. If you look at a "complete amino acid" supplements they are just fucking proteins with a few free amino acids. Most amino acids are commercially produced by breaking down protein!

You think you get the same amino acids in broccoli as with BCAA powder.
Again you are attributing to me an opinion I never stated.

You think broccoli is rich in amino acids.
Broccoli is rich in amino acids. BECAUSE IT'S HIGH IN PROTEIN.

You said supplementing BCAA is expensive without knowing how much humans require.
You need 10s of grams of protein per day so you need 10s of grams of various amino acids, and to restate, yes you need more than the three amino acids, which isn't actually helping your case. Can you source all the amino acids you need to live? (you can actually it's called rice and beans)

If you actually followed your own advice and ate only protein without considering calories, you would die. Thankfully for you, your "protein" diet is just having chicken breasts instead of pasta once a week and over-confidently commenting about it.
You cretinous fucking retard, calories are easy. Get the protein you need and then the rest is fat and carbs. Fat and carbs are easy. I just made some garlic bread. It was like three dollars for a brazilian calories of carbs and fat. Easy.

You have a weird fucking idea about amino acids. Protein is a macro nutrient. It isn't like a vitamin where you need milligrams or less per day. You need tens of grams of protein, and you are going to get it from- protein. How much amino acids do you think you need in a day? You need tens of grams. Do you know how I know that because you need tens of grams of PROTEIN a day. You need a good mix of them and plant and animal proteins are how you get them.

Free amino acids in food are in the micrograms per gram range. You need a two orders of magnitude more than that. YOU GET THEM FROM PROTEIN. FULL STOP. You can take some creatine powder and get some that way but that creatine was manufactured by breaking down whey PROTEIN.

Your whole idea that you don't need protein is fucking bizarre. YOU ARE MADE OF PROTEIN! Stuff wears out in you, and it's replaced with MORE PROTEIN, and this protein is in fact made up of amino acids but those amino acids got into your body when you chewed up and digested food with MOTHERFUCKING PROTEIN. WHAT THE FUCK IS WRONG WITH YOU. It's one of the three macro nutrients, and fat and carbs can be converted from one to the other but they can't be converted into protein because they don't have NITROGEN. You know what has NITROGEN, yes PROTEIN, and also amino acids which are the monomer that makes up PROTEIN and got into your body when you ate PROTEIN which your body broke down into PEPTIDES (if I were a raging tard like you I would say "oh you didn't know about PEPTIDES until today" but I don't assume someone doesn't know about something because they haven't mentioned it yet because it was irrelevant!) and then the PEPTIDES are broke down into AMINO acids, but in terms of nutrition they got into your body because you ate PROTEIN, a very necessary macronutrient!
