Beth Czerwony of Cleveland Clinic on lower summer appetite

Registered dietitian Beth Czerwony of the Cleveland Clinic explains that when temperatures rise above 30 °C the body reduces hunger to limit additional heat production. Increased outdoor activity, lighter food choices and dehydration further dampen appetite. She advises drinking water regularly, consuming small frequent meals and choosing foods with high water content such as fruit, vegetables, yogurt and lean protein, while avoiding heavy, fried or sugary dishes and excessive alcohol. The same physiological response reverses in colder months, where the body’s energy demand for warmth can increase appetite. The explanations were featured in health articles in Slovenia and Croatia.

“When it’s very hot, the body tries to limit the generation of extra heat, so the feeling of hunger is often less pronounced,” Czerwony said.
