Older adults need more protein than many younger adults, according to a review published in a 2004 edition of the “Journal of the American College of Nutrition.” The review reports that although the recommended dietary allowance, or RDA, for protein is 0.8 grams per kilogram of body weight, older adults require at least 1 gram of protein per kilogram, or about 0.45 grams of protein per pound of body weight each day, and even more protein during times of physiological stress. Due to difficulty chewing or concerns about high food costs, high-quality protein foods may be less accessible in the elderly population.
In one of his recent articles on 'Cell metabolism' Prof Longo and his team have observed that, after age 65, the body does need more proteins. So his suggestion is not to moderate proteins too much (without going to the opposite direction though). I think he suggests 1 grams /kg ideal weight/day of proteins. More than that, you may be triggering mTOR and the IIS which you do not want.
However, he does suggest a fast mimicking diet (FMD) in between his longevity diet (which is vegan based + fish twice ir thrice a week). His FMD is an700 to 800 calories daily regimen (vegan, mainly vegetables) extended throughout 4 or 5 days. It has been proven to regenerate the immune system and is believed to make up a natural shield for healthy cells while chemiotherapy hits the cancer cells (experiments on rats plus clinical trials on men).
That's a very interesting longevity diet + regimen which I'm going to study and modify accordinbg to my needs.
I'm definitely going to start a FMD, the fact that it can cause a rejuvenation of the immune system by hemopoietic stem cells regeneration is incredible. The biological effects are similar to an only water fast, according to prof. Longo, an authority on longevity who presently is 47 but just looks younger.
