If you develop a tolerance to caffeine, do the fat burning effects become reduced?

I've finally built up my tolerance so that I don't over react to my love of coffee. I can drink it now and not become too stimulated. That's nice, but I wonder if the fat burning effects get affected by the tolerance issue??

Another nice effect is that appetite control in low calorie has improved. But that could be a new fat set point as I've become pretty lean :)

according to: http://examine.com/supplements/Caffeine/

It appears that the answer is yes and no. The stimulant effect on fat burn is directly related to tolerance, and thus tolerant means less fat burn.

Caffeine has the mechanisms to increase metabolic rate and fat loss, but this is a mechanism that one can become desensitized to. Best usage for caffeine as a stimulant for weight loss should be intermittently and in conjunction with caloric deficits.

However, it also appears that there are antioxidant, intestinal uptake of fatty acids, alertness, and appetite suppression benefits that do not appear to be affected by tolerance.

So the answer is Yes, the fat burning effects are reduced, but only wrt to the metabolic change.
