Tag: Caloric Restriction

April 12, 2021
In this episode of X10, we discuss the concept of intermittent fasting: what it is, how it differs from caloric restriction, whether or not it can make you live longer or healthier, and the methods of going about it. Script This is part of a series of videos on diet and longevity. Last time, we...
Many foods contain selenium such as nuts, eggs, mushrooms, and some meats.
April 05, 2021
A recent study has shown that mice given selenium supplements were protected against the effects of a high-fat diet, similar to mice with a restricted methonine intake. Methonine restriction and caloric restriction It is well known among the longevity community that restricting calories leads to health benefits, and the practice of caloric restriction (CR) is...

In this episode of X10, we discuss the practice of caloric restriction along with its effects, which involve the TOR signaling pathway, epigenetic alterations, and DNA repair.  Sources Colman RJ, Anderson RM, Johnson SC, Kastman EK, Kosmatka KJ, Beasley TM, Allison DB, Cruzen C, Simmons HA, Kemnitz JW, Weindruch R. (2009) Caloric restriction delays...
Rapamycin
January 27, 2021
Although rapamycin reliably extends lifespan in a range of organisms, new research shows that it does not achieve this via the same pathways as caloric restriction [1]. Understanding how the two processes differ and interact could help researchers eventually piece together the longevity puzzle. Caloric or dietary restriction (CR) is perhaps the most robust, effective...

Glucosamine is a polysaccharide that naturally occurs in cartilaginous joint tissues and is involved in protein and lipid synthesis. Glucosamine is also present in other tissues, such as skin, nails, bones, and ligaments. Synovial fluid contains glucosamine and occupies the space between joints, helping to reduce the friction of joint surfaces. Glucosamine is commonly taken...
The Sheekey Science Show's Youtube image on fasting
January 21, 2021
n this video, the Sheekey Science Show discusses the different types of fasting (periodic and intermittent) and how they relate to aging, including their beneficial effects on metabolism and stem cells, along with the concept of refeeding. Supplements that serve as caloric restriction mimetics, which replicate some of the effects of fasting, are also explored.
