WEB DESK, June 29(ABC): Have you ever noticed that after some workouts you are absolutely famished, yet after others, you have no interest in food at all?

It turns out there may be a physiological reason for this having to do with how different types of exercise affect the production of chemicals within your body. And, researchers say appetite suppression after exercise may be due to a particular molecule that they have dubbed “Lac-Phe.”

However, it wasn’t just any type of exercise that triggered the most production of this molecule. More intense workouts were linked to larger amounts of Lac-Phe in the blood, while easier sessions were associated with lesser amounts of the substance.

This finding led the team to speculate that increased Lac-Phe production during more vigorous exercise could suppress appetite and thus lead to reduced excess body fat.
