Thinking, of all things, can make us overeat. Studies show that intellectual activities -- from reading to writing -- can make people eat more than when they're merely resting. Researchers discovered that intellectual work leads to more pronounced fluctuations in glucose levels than rest periods, perhaps because of the stress of thinking. The body reacts to these fluctuations by demanding food to restore glucose, a sugar that serves as the brain's fuel. Glucose is converted by the body from carbohydrates and is delivered to the brain through the bloodstream. Because the brain cannot produce glucose, it needs a constant supply. Moreover, brain cells require twice as much energy as other cells in the body. Interestingly, studies in animals have shown that consuming fewer calories overall leads to sharper brains and longer life, and most researchers concur that the findings generally extend to human beings. Caloric overcompensation following intellectual work, coupled wi...

Ironic that I would create a post about this on Thanksgiving of all days, isn't it? But I find it a germane topic in light of the fact that many of us won't be happy when we step on the scale tomorrow morning. In fact, studies show that many people decide to go on diets the day after Thanksgiving as a way of mitigating the damage. Whether they keep the diet when Christmas and New Year's come rolling around is a different story. Here's my trick to losing weight: The best way to exercise self-control is to ask yourself how many calories eating that scrumptious slice of pizza would set you back. The key is to mull this over before you even put the food on your plate. If you do it the other way around, you'll feel as though you've committed to eating it ("it's on my plate already -- might as well eat it) and will feel bad putting the slice back in the box. Now, that doesn't mean you can never "cheat" once in a while. After all, experts...
