Higher-temp workouts may help diet

LOS ANGELES A new study in the American Journal of Clinical Nutrition found men who exercised in warmer conditions ate about 300 calories less than those who worked out in cooler temps.

The men were tested on 40-minute runs at both 97 degrees and 77 degrees.

Experts say the men who worked out in the heat had higher blood levels of a hormone that dulls appetite.
