Googlαρε τον Dr. Jason Fung αν σε ενδιαφέρει το ζήτημα και μη παραθέτεις άσχετα άρθρα.
Το δεύτερο άρθρο , το οποίο υποθέτω πως δεν διάβασες , έχει αρκετές θέσεις που αξίζει να ανεφερθούν.
Tl;dr: Το intermittent fasting βασίζεται σε κάποιες αρχές που έχουν νόημα, υπάρχουν ιατροί που δείχνουν ενδιαφέρον για τις απόψεις του Dr. Fung , ωστόσο η πρακτική αυτή δεν δουλεύει για όλους και δεν έχει μελετηθεί κλινικά συνεπώς δεν ξέρουμε τα μακροπρόθεσμα αποτελέσματα της εφαρμογής της. Γι'αυτό οι γιατροί προτείνουν "συμβατικά" προγράμματα διατροφής , τουλάχιστον μέχρι οι γνώσεις μας περί του θέματος να διευρυνθούν.
Despite his unconventional views, Dr. Fung is winning some converts in the medical profession. “It’s not for everybody, but if someone is motivated, it sure makes sense as a way to lose weight,” says Dr. Martin Strauss, a cardiologist at North York General Hospital.
Dr. Fung agrees that not everyone will succeed at intermittent fasting. He also notes that patients need medical supervision – especially if they are taking diabetes medications. The doses of their drugs will likely need to be adjusted over time.
He says patients with diabetes should at least give it a try. “If you don’t like it, or you feel unwell, you can stop immediately.”
But most doctors are unlikely to recommend intermittent fasting without more scientific evidence that it can produce lasting results.
“We need a proper study with enough patients for a long duration of time to really prove whether this is safe and effective – or harmful,” says Dr. Jeremy Gilbert, an endocrinologist at Sunnybrook Health Sciences Centre in Toronto.
“All diets work in the short-term, but it’s the maintenance phase that’s so difficult,” he says.
There is a risk that those who attempt it and fail could end up worse off, speculates Annie Hoang, a registered dietitian at Sunnybrook. An individual’s metabolism might switch into “starvation mode,” reducing the amount of energy needed at rest, she explains. That means some patients could regain all the weight they lost – and more – if they stop doing intermittent fasting.
Dr. Fung argues that won’t happen.
Whatever the case, Dr. Gilbert says, “this diet has some extreme components some of which makes sense, but it’s not clear how many people can actually do what he (Dr. Fung) is recommending indefinitely.”
Dr. Fung says he has personally treated more than a thousand patients over the past five years “with many of them sustaining their non-diabetic status over the duration.”
But he has not yet published in a peer-reviewed journal the data showing his patients’ actual rate of success.
“Intermittent fasting is not something I would necessarily recommend until we know more,” says Dr. Nicola Guess, a lecturer and nutrition researcher at King’s College London.
