Coffee and Health!

Here is an interesting study on coffee, and it just so happens the research takes place while subjects are fasted, so bonus points:


In conclusion:

"Drinking 200 mL (1 cup) coffee induces an increase in the resistance of LDL to oxidative modification, probably as a result of the incorporation of coffee's phenolic acids into LDL."  

In other words the thing that makes LDL harmful to your arteries, which is oxidation, is slowed down by coffee consumption. 

This is a very interesting study on my good friend coffee.  Coffee increases metabolic rate, lipolysis, and most important fat oxidation in normal weight subjects.  It is noted that obese subjects did not benefit significantly from coffee.  

Take a Look: COFFEE!!!

In conclusion here:

"A series of four trials was carried out to investigate the effects of caffeine and coffee on the metabolic rate and substrate utilization in normal weight and obese individuals. In the first trial 8 mg/kg caffeine was compared with a placebo in normal weight subjects. Metabolic rate increased significantly during the 3 hr after caffeine ingestion. While plasma glucose, insulin, and carbohydrate oxidation did not change significantly, plasma free fatty acid levels rose from 432 +/- 31 to 848 +/- 135 muEq/liter and were accompanied by significant increases in fat oxidation during the last hour of the test. In the second and third trials the effects of coffee providing 4 mg/kg caffeine were studied in control and obese subjects. Metabolic rate increased significantly in both groups; however, significant increases in fat oxidation were only observed in the control group. Plasma free fatty acids did not change in the obese. In the fourth trial, coffee was taken with a 3080 kJ meal. The thermic effect of the meal was significantly greater after coffee than after decaffeinated coffee and again fat oxidation was significantly greater after coffee. In conclusion caffeine/coffee stimulates the metabolic rate in both control and obese individuals; however, this is accompanied by greater oxidation of fat in normal weight subjects."

So yes, coffee is great while fasting, but more importantly, have a strong brew after heavy meals for it's special benefit of greatly increasing thermic effect and fat oxidation.  I'll drink to that!
