The argument that TMHNET uses is all to do with the lack of research. Well there has been research done, and there is ongoing research. There is no research, afaik, that says that the 5:2 diet is unhealthy or bad for you.
The current diet advice being peddled by the NHS, is to eat healthy foods to a prescribed amount of calories and excercise. Well guess what? there are millions of people that are overweight, some obese, some morbidly obese, despite them knowing to eat less and move more. They simply can't do it.
And simply keep repeating the advice to them is unlikely to work.
So there needs to be another way. Perhaps 5:2 is it, perhaps not. But if nobody gives it a go, we'll never know.
I have been doing it since the first week in January. I have lost 3 stone. I have lost 5 inches from my waist. I have lost 7 inches from my stomach. I feel great and have loads of energy. I could do it forever, it is that easy. On my 5 days i eat and drink what I want, no restrictions whatsover.
If either of you know something I don't, lets hear it.
