  1. Over consumption of protein is a huge issue, clearly Peter is not up on the latest longevity science. Top experts such as David Sinclair and Valter Longo will tell you that too much protein activates mTor which is directly responsible for speeding up the aging process. Advocating for 2g/kg protein is too high and is not in line with the science and is not good for health.

  2. Fasting starts about 3 hours after the last meal is fully digested. There is no physiological difference between 2 or 48 hours of fasting, although obviously more stored calories are used (we have over 50,000) and therefore more weight is lost during longer fasts. Autophagy happens most of the time to some degree, there is no magic threshold when it starts. Longevity from fasting only occurs in lab rats. People try to make money selling information which is hypothesised and not proven.

  3. This is very interesting.I work as a roofer.This is a very physical job.I do have insulin resistance,but fasting causes me to feel very week at work sometimes.What good strategy could I work in this case?
