Hot not: M & F's gauge of the ins + outs in the world of health and fitness

HOT: BEEF JERKY

* Chicken is the most popular protein source for bodybuilders (partly because it's easy to tote around), but beef's benefits make it a worthy contender. Researchers at the Rippe Lifestyle Institute in Shrewsbury, Massachusetts, found that beef and chicken were equally effective protein sources for weight-loss and lower cholesterol. Want portability? Try jerky--with 13 grams of protein per serving, top brands like Pemmican pack a protein punch.

NOT: STARVATION DIETS

* Sure those freaks who eat less than 1,000 calories a day are doing it because there's some proof that mice on starvation diets live longer than their fat furry friends. Turns out that while those old, hungry mice are better at certain physical tests involving grip strength and flexibility, they fared worse than their well-fed peers on tests of cognitive function like memory and spatial learning. So you choose: Longevity or brains?
