Do they yield the same results? Would the 7 day fasts be more tolerable and safer?
This is what Dr. Jason Fung said on the topic:
“Longer fasts have more power, but more risk. To me, there is no reason to fast for 30 consecutive days just for the sake of argument. Why not do 4 separate 7-day fasts instead? It will have roughly the same beneficial health effects with far less risk.”
What do you think?
If you re-feed well, and can actually get back to fasting, then great?
Also I personally do have more energy to exercise following a re-feed. On longer fasts I tend to slowly lose the energy (but I have enough to keep things up)
