Caffeine as a cutting supplement...?

So this is my first post, I've been reading here for a bit and have been very impressed with the knowledge level. I started lifting within the last month or so, after not having lifting since HS (I'm 23). I've been looking around for info on diet, workout regimens, supplements, etc., and ran across this at a site I read all the time, thought some people here might find it interesting.

So I ran across this article, http://arstechnica.com/journals/scie...skin-thank-you which I found to be quite interesting, so I looked at the studies cited in the article.

This is a study that basically found that drinking coffee reduced the chances of developing liver cancer, and that the reduction was even more heavy in those with pre-existing liver damage.

The second study had to do with caffeine and exercise being synergistically beneficial to help reduce the risk of developing skin cancer, but had some other interesting side effects, namely that sub-dermal fat layers reduced dramatically in test subjects, with losses of 38%, 42%, and 68% over a 2 week period. Now there's some results!

I was thinking about possibly taking some caffeine pills and/or drinking some herbal teas and seeing how things went, and was wondering if anyone else had tried using caffeine before or knew anything about it. I'm thinking that because the mice were getting the caffeine in their drinking water, that it would probably be best to consume caffeine to try and keep a consistent level in the body throughout the day, as opposed to say before working out or something. An interesting read if nothing else.

caffeine is a GREAT supp to use!

preworkout, precardio--whatever u feel like!

here is a good read on it... just thought you would like...

Fast Facts on Caffeine: Performance Benefits for Athletes
Written by Holly Ortlund, M.S., Director of R&D, Carb-BOOM, Inc.

Introduction
Don't expect to see an espresso machine at an aid station during your next event, but there's a growing amount of research indicating caffeine can improve your performance.

So if you're now thinking “Hey, I can set a PR if I hit a Starbucks before my next race,” you should read on and learn about the beneficial effects of caffeine.

Legitimate Benefits?
Once thought to be a ‘nutrition no-no' for athletes, caffeine has taken center stage in the past few years as a legitimate aid to performance. This benefit has been recognized by the makers of sports nutrition products like energy gels.

A growing body of laboratory research supports caffeine as an effective ergogenic aid. (An ergogenic aid is a substance that improves athletic performance.) The most dramatic performance improvements (20-50 percent) are seen during prolonged (over two-hours) endurance exercise (3,4,7,8,9,12). Caffeine is also reported to benefit short-term intense exercise lasting about five minutes at maximal output (1,2,10,11).

How Caffeine Can Work for You
To maximize the benefits of caffeine, an athlete should consume 3-6 mg of caffeine per kilogram of body weight (roughly 2 mg/lb. of body weight) about one hour prior to exercise. For example, a 120-lb. person should consume roughly one to two cups (8 oz.) of drip-percolated coffee. A 175-lb. person would need to drink two to four cups. (Carb-BOOM!'s Vanilla Orange and Chocolate Cherry each contain approximately 50 mg. of caffeine.) See Chart 1 for caffeine content of other common foods/drinks.

The majority of lab research shows ingesting caffeine one hour before exercise results in enhanced performance. Few studies have been done on the possible ergogenic effects of caffeine ingestion during exercise. Although scientific research is still slim in this area, many endurance athletes believe that ingesting caffeine during prolonged exercise gives them an extra mental perk, increased focus and refreshed motivation.

Caffeine is well-known as a diuretic, therefore, it's reasonable to assume that athletes might have concerns about its effects on hydration. However, several studies conclude that no changes occurred in core temperature, sweat loss, plasma volume, urine volume or body hydration status during exercise following caffeine ingestion (5,6).

The Chemistry of Caffeine
The exact mechanism(s) of caffeine's ergogenicity remains unclear. More research is needed to fully elucidate the answer; however, three main theories exist.

Central Nervous System
This explanation involves the central nervous system (CNS). Caffeine stimulates the CNS, which would positively affect the athlete in two ways: through perceived exertion and through increased neural activation of muscle contraction.

Explained in more simple terms, caffeine ingestion may help the athlete ‘feel' better and more alert. So a boost of caffeine might make mile 19 of a marathon or starting the third leg of a triathlon feel not as hard. Along with this enhanced focus and clear-headedness, caffeine affects the CNS by stimulating the nerves to fire muscles into action more effectively.


Skeletal Muscle
The second theory focuses on the direct effect caffeine has on skeletal muscle performance. Caffeine produces changes in calcium activity, which stimulates the ion transport of potassium into non-contracting tissues. The ion transport leads to a reduction of the typical rise in plasma potassium concentrations occurring during exercise. It is thought that lowered potassium levels in the plasma help to maintain the excitability of the muscle fiber. More simply put, caffeine may benefit the athlete by helping to produce a longer (and possibly stronger) muscle contraction.


Metabolism
The third theory involves the ‘classic' metabolic explanation of caffeine's benefit to exercise performance. Caffeine increases the release early in exercise of free fatty acids into the blood. The increase in fatty acid availability leads to increased muscle fat oxidation and decreased carbohydrate oxidation, thus sparing muscle glycogen for use later in exercise. The extra store of glycogen benefits the athlete by delaying the onset of fatigue.
None of the above three theories alone can fully explain the ergogenic effect of caffeine. Different types of exercise (endurance versus short term) probably see performance improvements from different mechanisms (metabolic versus muscle). Another explanation may be that caffeine ingestion affects changes in the central nervous system, skeletal muscle, and metabolism, so that all three mechanisms work together in some capacity to benefit exercise performance.

Give It a Shot!
If you haven't tried caffeine as part of your training/racing regimen it's worth a shot! You may see an improvement in your race times as a result. Keep in mind that variability can be large. Regular caffeine users may see different responses than non-caffeine users and females may vary from males. You'll need to experiment to find out what works best for you. Try ingesting caffeine prior to exercise, during exercise and a combination of both. Experiment with caffeine during a long training bout versus a short interval-type workout. It may take a few training sessions to figure out the optimal timing and dosage for your body, but achieving a new PR might just be the end reward.


Fast Facts On Caffeine and Exercise

Caffeine ingestion can benefit endurance performance when consumed in proper amounts (2 mg/lb. of body weight) approximately one hour prior to exercise.

Timing is important. The benefits of ingesting caffeine approximately one hour prior to exercise are well supported. The benefits of caffeine ingestion during exercise is less clear.

Caffeine is no longer a banned substance as designated by the IOC.

Athletes need not worry about any adverse diuretic effects of caffeine

If your gonna supplement caffeine in a cutter.You should just run an ECA Stack. (Ephedrine HCL, CAffeine, and Aspirin)

But your diet will be the most important part of it all.

BTW, welcome to the board.

Good info Pewn.
