Some of that article is really interesting stuff, but I think overall they're looking for the wrong results.
>any regimen involving fasting beyond 24-hours has not been proven effective in sustaining weight loss long term.
It's not supposed to be about weight loss, right? It's about autophagy, increasing insulin sensitivity, etc...
>The other obvious safety concern with fasting, whether intermittent or sustained, is its effects on medication requirements to manage diabetes .... medication requirements for adequate blood glucose control are dramatically reduced in just the first day or two of fasting or carbohydrate restriction
>Similarly, blood pressure is often markedly reduced in just the first few days of fasting
One doctor's concern is another doctor's desired outcome?
