I think the idea is to temporarily raise triglyceride levels and use them as an immediate fuel source thus extending the life of the glucose stores.
In posting that I think I answered my own question, that is consume caffeine only at the beginning.

It seems real risky to me. I am a person who doesn't drink coffee or cola because I am aware of what caffeine does to the body with respect to hypertension, heart disease, osteoporosis and so on. Raising the fatty trigs even temporarily seems inherently dangerous to me because if the fatty trigs continue to go up, and not come down, then a person will have high cholesterol and clogged arteries.
I won't even buy the Clif Bloks with the added caffeine.
My mom and two older sisters were/are avid coffee drinkers. All of them got advanced osteoporosis and it was attributed to their caffeine consumption; my mother suffered horribly for years before she died. Whereas I avoided coffee and cola all of my life and my bone density is so strong the number is off the top of the scale.

I don't think there's reason to be that scared fo triglycerides - The only way of utilizing body fat is mobilizing it from adipose tissue into the bloodstream and then burning it in the place of energy consumption i.e. muscle. Hence it must go into the bloodstream as free triglycerides if you want to burn any. So I see no risk there of having an elevated triglyceride level while you exercise. Also note that it's free fatty acids and not lipoprotein bound (HDL/LDL) fatty acids so there will be a different (read likely not negative) impact on the CV system.
Also no need to be scared of coffee in moderation -
So.... enough calcium in your diet, and the occasional pre-or during ride coffee, caffeinated gel, and you're fine. I'm not saying there is no danger if you have 16 espressos a day.From the Journal of AMA: (JAMA, 26 Jan. 1994, p. 280-3.)
"There was a significant association between (drinking
more) caffeinated coffee and decreasing bone mineral density at
both the hip and the spine, independent of age, obesity, years
since menopause, and the use of tobacco, estrogen, alcohol,
thiazides, and calcium supplements [in women]."
Except when:
"Bone density did not vary [...] in women who reported
drinking at least one glass of milk per day during most of their
adult lives."
Then there's the stimulant effect, towards the end of a long hard ride it will help you overcome fatigue. It also suppresses hunger which may or may not be a good thing.
As a negative impact, you will excrete some more water (and I always have to go to the loo 45 min into the ride, if I've had coffee). Also blood flow to the heart will be somewhat restricted resulting in a higher heart rate.
Lance would get up at 6 am, have 4 espressos (!), and then stretch for an hour. So it seems to work.

Caffeine is a drug. It has stimulant effects, which can improve concentration for most people (and of course has performance enhancing effects). It is one of the oldest asthma drugs. It is a diuretic (which you actually *want* sometimes). It can also be used as a "booster" for other drugs, to help them take effect sooner. It's powerful stuff, and used appropriately has few undesirable side effects.
For someone like me, who is asthmatic and allergic to the standard emergency treatment asthma drugs, caffeine is a godsend. It means I can get safe and effective emergency treatment almost anywhere.
Just like any drug, not everyone should take caffeine. But I'm glad it's available, or my life would be a lot worse.
VERY INTERESTING post! Since I was diagnosed as a type 1.5 diabetic, and had to eat low carb even on the bike, I started ordering an iced coffee at the rest stop on my long rides and feel great. Now I know why it works. I agree with the posters that say triglycerides in the blood during cycling is a GOOD things, at least for those of us who ride to burn excess body fat, or need to burn a higher ratio of fat than glucose for fuel for whatever reason.
For me, there is a strikingly direct correlation between having that ucp of tea in the morning and being able to think clearly. I have done too many things like put my wheel on backwards (chain facing the wrong way) to even remember 'em all (don't ask me about that meeting...) too many times. I quite honestly am risking my life more not drinking small amounts of the stuff than doing it.
Can I just say how happy I am to read this? I LOVE a cup of coffee in the morning and I have one just about every day. I have been skipping it on morning ride days for fear of the dehydrating effects, but I swear that I don't pee any more frequently on my non-ride days.
Good, now I'm going to go ahead and have my normal cup of coffee and feel good about it!![]()
