Role of skeletal muscle autophagy in high-fat-diet-induced obesity and exercise

Nutr Rev. 2020 Jan 1;78(1):56-64. doi: 10.1093/nutrit/nuz044.

Abstract

Autophagy is a complex degradation pathway responsible for clearing damaged and dysfunctional organelles. High-fat-diet-induced obesity has been shown to alter autophagy throughout the body in a tissue-specific manner. The impact of obesity on skeletal muscle autophagy has yet to be elucidated. This review examines the impact of high-fat-diet-induced obesity and exercise on skeletal muscle autophagy. Better understanding this major quality control mechanism may help develop novel therapies to combat high-fat-diet-induced obesity comorbidities.

Keywords: autophagy; exercise; high-fat diet; obesity; skeletal muscle.
