Is Heat an Appetite Suppressant?

A small study was just conducted that showed that men who exercised in hot temperatures were less inclined to eat a lot of calories after working out.

Researchers believe it may be that since the men exercised in hot conditions it raised their core body temperature to a higher degree which shut down their appetite. This is believed to be the case since eating would further heat up your body and as a result your appetite would naturally be suppressed. It’s also the reason why cold temperatures may increase your appetite.

Even if this study is true, neither the researchers nor I recommend working out in extreme heat or unsafe conditions. Your safety and health should always be your top priority, but this study may explain why you sometimes feel less hungry after an intense workout.
