The specialist noted that muscle performs essential functions not only in strength and mobility, but also in the generation of mitochondria. These structures produce both free radicals and antioxidants, making muscle tissue a key regulator of metabolism and health.
He explained that new muscle synthesis is activated through the mTOR pathway, which is especially stimulated by the leucine present in animal proteins and by hormones such as growth hormone and IGF-1. However, he warned that excessive activation of this pathway is associated with an increased risk of cancer and a shorter life expectancy.
According to Dr. Bayter, the problem lies not in the mTOR pathway itself, but in the methods used to stimulate it. High carbohydrate consumption and the use of external hormones, as is the case with bodybuilders, are factors that reduce longevity and can increase health risks.
He recommended moderate strength training, for one to one and a half hours, three to four times a week, preferably on an empty stomach and accompanied by a diet based on quality protein, plenty of rest, and sun exposure. These practices allow you to take advantage of the benefits of the mTOR pathway without compromising longevity.
The specialist concluded that the key to a long and healthy life lies in maintaining optimal muscle mass, avoiding both a sedentary lifestyle and excessive exercise, and regulating circadian rhythms with adequate sleep and stress management.
