Coffee vs Insulin

[Jordan]

I recently heard (on extreme makeover : ) ) that too much coffee can cause insulin spikes. Being a coffee drinker, id like to clarify this... has anyone heard this to be trueÉ I always have a cup of coffee in the morning about often a second one in the afternoon-evening. Would anyone say this is a bad idea from a bodybuilders perspectiveÉ thanks,

Not for sure, but according to shpongled's article on caffeine, I would think that it wouldn't.

"Insulin resistance - Acute administration of caffeine (the equivalent of 3-4 cups of coffee, in other words 300-400 mg) causes insulin resistance in sedentary males with skeletal muscle as a major contributing factor, although this only occurs in the presence of above normal insulin levels2. Also, tolerance to this effect develops18. Possible mechanisms of action include adenosine antagonism in skeletal muscle, increase in FFAs, and increased epinephrine concentration (the most likely cause, since caffeine-induced insulin resistance is reversed by the beta blocker propranolol)2, 49. Caffeine does not impair exercise-induced increases in insulin sensitivity, indicating that the effects are independent of one another2. Although caffeine significantly improves athletic performance, if one is trying to gain appreciable amounts of muscle mass, using large doses of caffeine pre-workout may not be a good idea as inhibition of muscle glucose uptake may be counterproductive to that goal."

They were probably referring to the people that load their coffee with sugar, which of course would cause an increase in insulin.
