If the heat outside is making your insides revolt against food, you’re not alone. Health experts say that the weather has a big impact on one’s appetite.

Researchers say that as the temperature increases, a person’s appetite may decrease.

“It actually has to do with the thermic effect of food, so we’re not as hungry in the heat because our bodies don’t wanna get overheated,” says Julia Zumpano, a registered dietitian with the Cleveland Clinic.

Zumpano says digesting food and stockpiling nutrients uses energy, which generates heat. She says that if one’s body is already hot, it may not want any more heat.

"So generally and naturally, our appetites just drop in the summer and in the hotter months,” says Zumpano.

But even if you’re not as hungry in the heat, Zumpano says it is still important to have a balanced diet. She says to choose the most nutrient-dense foods, like fresh fruits and vegetables. She says to also make sure you’re getting enough protein.

“Proteins can come from meats or fish, but it can also come from things like eggs and beans and dairy sources, like cottage cheese and Greek yogurt,” Zumpano says.

Zumpano finally says that digestion can slow down when a person is dehydrated, so it is important to drink plenty of water.

"Even focusing on hydrating foods can be very helpful, like watermelon and lettuce and celery and cucumbers, cherries and citrus fruits and strawberries,” she says. “So all of those foods can be very hydrating, in addition to, of course, increasing your fluid intake."
