New Exercise Pill May Help People Lose Weight: Study Finds says researchers from the University of Florida have developed a new pill that promotes weight loss. The compound, called SLU-PP-332, tricks muscles into thinking they have been working out. This boosts metabolism and melts fat. The drug was tested on obese mice. It helped them lose weight and increased their endurance without any physical activity. Researchers believe the compound could someday treat obesity, diabetes, and age-related muscle loss.
