Aging is an energy deficiency problem, taking cardiolipin may reverse it

Yet another study demonstrating that “aging” is nothing but a phenotype characterizing an organism with declining energy production. Since most of the cellular energy is produced in the mitochondria, another way of stating the same is that aging (and any specific disease for that matter) is a mitochondrial dysfunction problem. Conversely, reversing that energy/mitochondrial deficiency … Read more

Inflammation (from PUFA), not telomeres, determines lifespan / healthspan

The idea of lifespan being entirely determined by limits on cellular division has ruled biology for more than a century and is perhaps best exemplified by the (in)famous (and false) Hayflick limit. Reaching the said limit is postulated to be controlled by telomere length, and as such the simplistic hypothesis materialized that could extend/control lifespan … Read more

Low DHT can cause hypogonadism symptoms even in eugonadal men

Seemingly contradictory title, but the study findings are pretty clear. Namely, even in males with normal testosterone levels there is a direct inverse relationship between DHT levels and symptoms of hypogonadism such as sexual dysfunction and “aging male” syndrome. For every 10% increase in DHT levels there was a 4.67% decrease in hypogonadism symptoms of … Read more

Niacinamide improves glucose metabolism and muscle health in humans

Niacinamide probably does not need in introduction to the people reading my posts. However, despite the multitude of animal studies demonstrating beneficial effects of this vitamin in virtually every chronic condition (and especially conditions associated with disturbed glucose metabolism), human studies with it are very scarce. The study below is one of those rare human … Read more

Blocking PUFA/prostaglandins restores metabolism and reverses brain aging

The bad news for PUFA has been accumulating for decades, yet public health authorities continue to claim that type of fat is “essential”. Whatever indirect admissions of the pathological role of PUFA in both chronic and acute/infectious diseases is given to the public, is usually confined to the well-known PUFA metabolites known as prostaglandins. However, … Read more

Low energy production (glucose metabolism) may cause andropause

As many of my readers know, aging men can also experience the equivalent of menopause and doctors informally call that state “andropause”. Its official name is age-related hypogonadism and most of that hypogonadism is of the “secondary” type – i.e. the gonads appears to be in fine shape but for some “unknown” reason they do … Read more

The Cure for Aging Might be the Cure for Alzheimer’s

Almost 25 years ago, Dr. Peat himself wrote a 2-article series in which he outlined arguments in favor of the hypothesis that aging and Alzheimer Disease (AD) are just examples of a more and less systemic sign respectively of declining energy production, and that curing one would lead to a cure of the other. http://raypeat.com/articles/articles/alzheimers.shtml … Read more

Policosanol is antiviral and a potent inducer of anti-aging gene Klotho

This post is a good complement to the recent ones I did on androgens, estrogens and their opposing effects on the expression of the anti-aging gene Klotho. While I was doing research on that gene, I had a “random” thought pop up in my mind. It is well-known that some Caribbean countries have a very … Read more

Androgens boost, estrogen inhibits, anti-aging gene Klotho

This post has two main messages, based on the studies below. Namely, androgens (and especially DHT) potently increase the expression of the anti-aging gene Klotho while estrogens strikingly decrease its expression. Moreover, the more potent the androgen, in terms of androgen receptor (AR) agonism, the more robustly it increases Klotho. Conversely, the most potent the … Read more

Childhood stress / deprivation leads to early puberty / aging

The evidence that adult health problems have their roots in childhood or even prenatally continues to accumulate. The study below demonstrates that children who have experienced violence, trauma, deprivation or have had generally stressful childhoods not only enter puberty much earlier but are on average several years older (biologically) than their peers. While being several … Read more
