|Image 1: If I had the choice to have a tasty cup of coffee with the beautiful young lady or a couple of overpriced raspberry ketone caps with Dr. Oz, I would not even need scientific studies to make my choice ;-)|
And what's more, picking cafeine over raspberry ketones would not only protect me and my virility from potential anti-androgenic effects of the latest nutraceutical rip-off (Ogawa. 2010), it could, according to a recently published study from the Department of Biological and Physical Sciences at the University of Southern Queensland in Toowoomba, Queensland, Australia, also help me to stay lean by simply blocking fatty acid synthase (FAS) in my adipose tissue (Panchal. 2012).
Caffeine? how boring is that!?
Contrary to the, as of late, often-cited study by Wang et al. on raspberry ketones (Wang. 2012), which is by the way one out of two peer-reviewed in vivo studies (the other one is Morimoto. 2005) to support the claim that raspberry ketones do anything, when they are not administered in unrealistic amounts to cells in a petri dish, Panchal et al. did not just measure a couple of serum markers, but investigated a host of metabolic parameters and structure and function of the heart and the liver of their 6-8 week old male Wistar rats that had been randomly assigned to what you might jokingly call the “pest or cholera” diets for 16 weeks: Corn starch diet (control), corn starch diet plus caffeine (CC), high-carbohydrate, high-fat diet (H), or high-carbohydrate high-fat diet plus caffeine (caffeine supplementation with 0.5g per kg chow took place only in the last 8 weeks of the 16-week study period).

- standard cornstarch diet, which consumed 28.1mg caffeine per kg body weight (~360mg for a human being) per day, were leaner than their peers in the “control” group and that despite a 20% increase in energy intake
- high carbohydrate + high fat diet, which consumed 47.9mg caffeine per kg body weight (~612mg for a human) per day, were about as lean as the rodents on the standard diet and that despite a 40% higher energy intake (3% more than their peers in the high carbohydrate high fat diet without caffeine supplementation)

The answer is pretty simple and "visualized" in image 2, it carries names such as "Peppermint White Chocolate Mocha" contains the sugar equivalent of 8½ scoops Edy’s Slow Churned Rich and Creamy Coffee Ice Cream and is "America's Worst Espresso Drink" - at least according to foodfacts.com. And while you can easily make it worse by adding some caramel syrup or junk, the average normal weight woman (if those still exist today) would almost get the +40% caloric intake the rodents in the high fat high carbohydrate diet consumed from that one "coffee" alone!
2-3 cups of black coffee would suffice!
