Men's Health Magazine had this piece on the new science of weight loss. Really quite interesting, and in some cases, counterintuitive. Here are some interesting facts:
* You could be increasing your body fat percentage by not eating! When your body needs energy, it burns muscle before fat, so if you don't get enough carbs, you burn muscle instead of fat!
* I have loved to bug my friends about this one - weight training is a MUCH BETTER method to lose weight than running or any other form of exercise. The difference is that weight training increases your resting metabolic rate (how many calories you burn while not exercising) and thus causes greater calorie burn.
There's a lot more, so I would read the story (even if you aren't a man!)
