Aging is characterized by a loss in muscle mass and function, which is defined as sarcopenia. It weakens individuals by increasing the risk of falls and altering their quality of life. The loss of muscle mass results from the age-related impairment of the anabolic effect of nutrients and insulin, which normally increase and decrease muscle protein synthesis and degradation rates respectively. Alterations in muscle protein metabolism have been related to the accumulation of body fat and intramyocellular lipids. In particular, some lipid species such as ceramides or diacylglycerols have been described as inhibitors of the insulin signaling pathway in different models. Accumulation of these molecules in skeletal muscle could result from a lowered buffering capacity of circulating fatty acids by adipose tissue in response to the meal, a reduction of mitochondrial oxidative capacities or chronic inflammation. However, some nutritional strategies have been identified to limit or prevent the accumulation of lipotoxic metabolites and to improve the sensitivity of muscle to nutrients or insulin.
