Some more caffeine ?

[anthrax]

I don't like that article at all but it may interest some of you heavy coffee drinkers...

BTW it is NOT a scientific studie....

In this study, a group of young, healthy, non-obese males consumed coffee (5mg/kg of caffeine) and then, 60 minutes later, consumed 75g of carbohydrate as either a high-GI meal (Crispix and skim milk) or a low-GI meal (all bran and skim milk).

While caffeine didn't have an effect on blood glucose or insulin after an overnight fast, caffeine consumption resulted in:

• 29% increase in insulin after high-GI meal (vs. decaf.)

• 44% increase in insulin after low-GI meal (vs. decaf.)

• 146% increase in blood glucose after high-GI meal (vs. decaf.)

• 220% increase in blood glucose after low-GI meal (vs. decaf.)

Again, whether we like it or not, it's becoming clear that caffeine does negatively impact glucose disposal, insulin response, and the glycemic index. The subjects in this study were regular caffeine users but did go through a 48h withdrawal before the test day, so I asked the researchers involved in this study whether this effect would be as pronounced without the withdrawal period. While they weren't sure, they did tell me that they are collecting those data as you read this and they should be published in the near future.

The big question I keep getting is whether or not the negative effects of caffeine will impact body composition. Since caffeine does increase metabolic rate and fat mobilization, the negative effects on glucose and insulin function may be neutralized with respect to body comp. However, since glucose and insulin homeostasis are linked to health, it's important to realize that even if coffee doesn't make you fatter, it may impair your ability to deal with carbohydrates.

Good info, as usual bro. You'd have to convince me that caffeine caused impotence to get me to quit, tho

I pound 10+ cups of heavy duty black coffee a day. Caffeine makes me happy...

Certainly not
BTW it is not t(hat kind of study that would keep me away from my expresso

I pound 10+ cups of heavy duty black coffee a day. Caffeine makes me happy...

you beat me !
@ 6 cups a day I am a "small" drinker

Well I'm a rank beginner at only 2 cups per day. However I NEVER have my coffee anywhere near a meal, so the glucose/insulin problem becomes a non-problem, and all I get from it is increassed fat mobiliztion and energy. All good.

And remember, ALL fat-burning/thermogenic drugs will increase your insulin and glucose response to a carb meal including ephedrine, NYC, clen etc.....This is due to the increase in blood free fatty acids that they liberate for feul....these intefere with insulin sensitivity. So the best advice is to avoid insulogenic meals when taking thermogenics.

5mg/kg? so if you weigh 220lbs, thats 500mg of caffeine....the equivalent of 10 mountain dews...about 15 or 20 cans of coke...anywhere from 5 to 10 cups of coffee depending on strenth...or two stacker 3's. Thats a shitload of caffeine, I wonder what the effects would have been like w/ a more realistic dose.

Impressive numbers but how come the eca stack is much more effective when caffeine is added? And some said a high caffeine intake is good for fat loss.

"And remember, ALL fat-burning/thermogenic drugs will increase your insulin and glucose response to a carb meal including ephedrine, NYC, clen etc"

I know it may be a weak thermogenic but doesn't the green tea increase insulin sensitivity?

 

[Judah Bauer]

well...there's the idea that caffeines negative effect on glucose tolerance is offset by...

increase fatty acid oxidation

increased metabolism

an increase in glucose tolerance after caffein wears off (kinda like a pendullum)...although i don't know if this is proven

or by the fact that these are MEGA doses of caffeine that might not be applicable to us



true other stimulants may increase the insulin response...i don't really know...but i do know that clen and ephedrine increase partitioning....

 

[anthrax]

caffeine is defenitively useful when trying to lose fat (and should be used when already take ephedrine)

Just don't take it right before/after a high GI carbs meal

anthrax. allways good to read your stuff on coffee.
