The findings, published today (August 2) in Cell Metabolism, may explain why intense dieting can be so hard to stick with, and help scientists develop novel therapies to fight obesity, according to the study authors.

“The present study identifies the missing link [between the brain and weight control] as autophagy,” said Vojo Deretic, chair of the University of New Mexico’s department of molecular genetics and microbiology, who was not involved in the research. “It is definitely an interesting paper that may lead to bigger ...
