An Appetite and Sun Connection


According to recent research from Tel Aviv University, exposure to the sun makes men more hungry but not women. The research, which was conducted using lab models, reveals how the metabolic mechanism is activated differently in men and women. 

According to the researchers, sun exposure in males of both animal species and humans triggers a protein called p53 to repair any DNA damage that may have been done to the skin as a result of the exposure.

Ghrelin, a hormone that increases hunger, is produced by the body in response to the activation of p53. The hormone estrogen prevents the interaction of p53 with ghrelin in females, which prevents the urge to eat after exposure to the sun.

Professor Carmit Levy and Ph.D. student Shivang Parikh of the Department of Human Genetics and Biochemistry at TAU’s Sackler Faculty of Medicine led the groundbreaking study. 

 It was carried out in partnership with numerous Israeli and international researchers, including Tel Aviv Sourasky (Ichilov), Assuta, Meir, and Sheba Medical Centers, as well as Dr. Yiftach Gepner and Dr. Lior Bikovski from TAU’s Sackler Faculty of Medicine and Professor Aron Weller from Bar-Ilan University. 

The study was published in the renowned journal Nature Metabolism.  READ MORE...
