Guest blogger, Eugene Wells is the author of The Decaf Diet: Is Caffeine Making You Fat? You can download and read the first 50 pages of the book for free on his blog, LastingLeanness.The caffeine in your daily coffee, tea, and soft drinks can lead to weight gain and make losing weight a losing battle. Caffeine can make you fat because it drives overeating and slows metabolism, by making your body increase its production of cortisol.
Cortisol is one of your body’s chief stress hormones, and caffeine’s impact on your cortisol levels can cause an increase in hunger, muscle breakdown, and a relocation of fat stores to your body’s center. If you are a regular caffeine user, your cortisol levels are chronically elevated. As a result, you become more prone to both physical and psychological stress, and the fat-promoting effects of elevated cortisol levels.
