Really interesting, Orange. Does he offer any
explanation for the increased protein for those over 65? Dan Buettner, who's done the most work with centenarians, would disagree with that approach as would Dr. Gundry and likely Dr. Bredesen unless hypoprotenemia or other obvious clinical signs of a protein deficiency were present. This is an important nuance for us to tease out.
I think it mainly seemed based on the centenarians he was looking at and what they ate. I will have a look in the book (
again later and check. He also recommended less times of doing the week of fasting-mimicking the more generally healthy you are, like every 6 months or so if better health and more frequently if more unhealthy / overweight etc. When younger I mean.
It looks like most of use with E4 would fall into the 'once every three months' category- 'for average weight patients with at least one risk factor for diabetes, CVD, cancer or neurogenerative disease"
OK, here we go. P84 Longevity Diet in Summary: (this is what he means to do generally- not during the fasting weeks but day to day)
"If you are below the age of 65, keep the intake of protein low (0.31 to 0.36 grams per pound of body weight) That comes to 40 to 47 grams of protein per day for a person weighting 130 pounds, and 60 to 70 grams per day for someone weighing 200 to 220 pounds. Those beyond age 65 should slightly increase their protein intake, including fish, eggs, white meat and products derived from goats and sheep, to preserve muscle mass. Consume beans, chickpeas, green peas, and other legumes as your main source of protein".
So it seems the explanation is about the muscle mass, I think. He also recommends muscle toning exercises so maybe that is related.
He says (P86) "Until age 65-70, depending on weight and frailty, undergo five days of fasting mimicking diet every 1-6 months" So it seems it is something he doesn't recommend for those over this age.
I noticed, he also recommends, in general 2 meals and day but 3 meals a day for this over 65- it seems it is not just about protein but nourishment in general.
