BRIDGING THE GAP
RESEARCH and PRACTICALITY
In one study on caffeine the researchers found elevated triglyceride (TG) levels in non-caffeine users with no change in serum lipids in regular coffee drinkers. In other studies the general consensus is that regular use of caffeine results in no significant change in total-, LDL-, or HDL-cholesterol or TG levels.
Several recent studies have also found that caffeine does not have the diuretic effects it once was thought to, particularly during exercise.
Overall, I would say caffeine poses little overall health risk and in moderation won't effect your blood lipids. With that said, and knowing your metabolism, I would recommend you test caffeines effect on YOUR lipid metabolism.
How would you do that, you might ask? Abstain from caffeine (if you can) for two to three weeks, take a lipid profile test (either with a home testing device or in a lab), drink beverages containing caffeine for a week or two and then re-test. Another indirect test is to simply follow the dietary recommendations I provided you and monitor your lipid values without changing your caffeine intake. If you blood lipid levels get to where we want them (through diet and without Rx meds) than you don't need to worry about caffeine and a tolerance test.
