Muscle weakness / wasting linked to poor mitochondrial function

A study that once again illustrates the central principle of bioenergetics – structure and function cannot be separated. They are interdependent at every level. In this specific case, the “structural” pathology is muscle weakness and wasting (sarcopenia, cachexia, etc). Most doctors, when evaluating such condition, will look for structural problems such as genetic mutations, trauma, … Read more

Vitamin D deficiency impairs muscles by lowering energy production

Perhaps this study below will put some of the arguments against vitamin D supplementation to rest. It demonstrated up to 40% reduction of energy production in the muscles of animals deficient in vitamin D, in spite of unchanged number/size/density of mitochondria inside the cells. In addition, it demonstrated decrease in lean mass in the deficient … Read more

DHT restores anabolism / vitality / sexuality even in 90+ y.o. males

A great study, a true blast from the (better) past, when androgenic steroids and especially DHT were not considered the devil reincarnate, but were commonly used for all types of ailments, including the broad physiological and psychological symptoms of aging such as sarcopenia (muscle loss), osteoporosis, senility, apathy/depression, and even sexual function. The study demonstrates … Read more

Intermittent fasting (IF) ineffective and may even be dangerous

I have no doubt the findings of this study will quickly get dismissed by the massive industry that has formed around the idea that ANY weight loss is a good thing, and, just as importantly, if you lose weight while torturing yourself (in this with fasting) somehow the “gains” are even more worthwhile. Well, the … Read more

Cholesterol and saturated fat are anabolic; PUFA/MUFA akin to chemical castration

A pair of interesting study and a commentary in the highly respected Journals of Gerontology. Namely, higher cholesterol intake is associated with much higher lean muscle mass accrual as a result of weight lifting. Interestingly, higher protein intake was not. Even more interestingly, and much to the chagrin of the medical industry, the increased dietary … Read more
