There are many comments of fasting diets, that also say that it could encourage poor overall control of the diet. What if without realising it some people are already becoming/become diabetic and fasting would not be a good idea, hypo's etc. What would also happen if these trying to fast, also started using the Victoza drug, to get more weight loss?? There was only s 6 week study done, maybe this information should not have been released this early. It also said that the cholesterol levels rose on fasting days, to be taken for energy production, well what are the effects on the heart while this use of cholestrol is being used? not happy with that idea, surley this would place too musch stress on a body that is already feeling under stress.
