Why Exercise Boosts Brainpower

aditi sends us a report from Reuters on research indicating that exercise boosts brainpower by building new brain cells in a brain region linked with memory and memory loss. Quoting: "Tests on mice showed they grew new brain cells in a brain region called the dentate gyrus, a part of the hippocampus that is known to be affected in the age-related memory decline that begins around age 30 for most humans. Researchers used magnetic resonance imaging scans to help document the process in mice — and then used MRIs to look at the brains of people before and after exercise. They found the same patterns, which suggests that people also grow new brain cells when they exercise."

      Good point. 5 miles day on salads is a recipe for disaster. Even if you're trying to lose weight you don't want to put yourself into that high of a caloric deficit. A better idea is just start eating healthier foods. No more fast food, cookies, chips, etc... Instead eat lots of veggies, unprocessed meats, unprocessed carbs, and some good fats. You'd be surprised how much of the good food you can eat before you hit your calorie target.

      Also, 5 miles/day isn't required to lose weight. In fact, if losing weight is your primary goal sprints are far more effective both in weight loss and time (although taking someone who truly is sedentary and moving them straight to sprints is dumb too).

A combination of weights-training, running and aerobic sports is usually a good idea.
