Could you answer the second part of my question about protein-sparing modified fast?

Chris Kresser:  Yes. Sorry about that. Generally you just watch. If the patient is doing it for just two or three weeks, I don’t think you have to worry too much about it. If they’re doing it for longer than that, you want to be monitoring for nutrient deficiency because their diet is going to be somewhat limited. You also want to make sure that they’re not too severely, there is no signs of too severe on the calorie restriction scale. Although it’s not a voluntary calorie restriction, you just want to make sure that they’re not starting to exhibit any unusual symptoms or signs that they’re not getting enough to eat. So but generally I will only have people do it for two or three weeks and they don’t need careful monitoring during that. In some of the studies they do it for longer and so they’re getting more regular testing during the lengthier periods.
