A major study has found fewer suicides among drinkers of Caffeine than those who abstained from the popular stimulant. The study of nearly 130,000 Northern California residents and the records of 4,500 who have died looked at the effects of coffee and tea on mortality. The unique survey also found no link between coffee consumption and death risk. The study was conducted by the health maintenance organization Kaiser Permanent and was reported Wednesday in the Annals of Epidemiology. Caffeine and your metabolism.
Caffeine increases the level of circulating fatty acids.
This has been shown to increase the oxidation of these fuels, hence enhancing fat oxidation. Caffeine has been used for years by runners and endurance people to enhance fatty acid metabolism. It's particularly effective in those who are not habitual users. Caffeine is not an appetite suppressant. It does affect metabolism, though it is a good question whether its use truly makes any difference during a diet.
