Pre-contest dieting: how much black coffee is too much?

[Big Aristotle]

I currently drink anywhere from 2-3 cups of black coffee per day now, just started doing this and i'm two weeks out from competiton. And just yesterday, i came up with a concauction of a pre workout meal. After taking my ephedrine, i usually have a shake an hour before training. Well, i decided to mix my protein shake with a hot coffee, for an extra buzz. Not only did i get the preworkout lift i needed but what a fucking cup of coffee. I mixed in vanilla whey protein powder and it tasted like a french vanilla capuccino. Amazing to the point where i felt i had just cheated on the diet.
Let me know what you guys think.

yes, you'd better have caffeine with your ephedrine

a good dosage is
X mg ephedrine HCl (ie 40mg)
10X mg caffeine (ie 400mg)

BTW 2-3 cups of black coffee is not much
I can have 7-8 ('cause I love it )

i love coffee so much


My name is Gymrat123 and I'm a coffee-holic.

I was under the impression that excessive heating could denature protein powder - rendering it useless as far as absorption is concerned....

...anyone have input on this? Because it sounds like a great idea....to make that black coffee taste better....but if it destroys the peptides....there's not much benefit....

 

[anthrax]

yes, heat cause protein chains to coagulate and denature

but mixing hot coffee with your powder is OK (but don't put the 2 in the microwave !)

BTW the albumen (egg white) loses its functionality at temperatures > 130°C

Lots of coffee......yum.

Biscuit...

I guess I am missing something here. How would that be different? Just curious as if this something that can work well I will be doing this today pre-workout.

 

[gymrat]

coffee is usually only warm. If you nuke something, you will heat it too much..

I actually discussed this with my doctor (the denaturing part) and denaturing a protein doesn't necessarily make it less absorbable.

The curds in cottage cheese are denatured milk proteins

Tofu is denatured soy protein

When egg whites go from runny & clear to firm and white...guess what? You guessed it!

Denturing simply means changing the tertiary structure of the protein. I think absorbability at best can only be assesed on a case-by-case basis. I have heard on numerous occasions that Raw eggs are LESS absorbable than cooked (denatured) eggs.

Therefore while lumpy curds in your protein coffee are nasty, I have seen no evidence that the protein has been rendered unabsorbable.
