I gave this diet a run about a year ago, and drifted away from it once my BMI had dropped to 22.5. Fast forward a year, and although I am happy with a slightly higher BMI of 22.7 I would like to drag my BG lower, and have started to consider my next move. I am toying with either a continuous 800 cal a day diet or a return to 5:2 On searching around I came across this http://phlauntdiabetesupdates.blogspot.co.uk/2016/09/i-report-about-my-bad-experience-with.html from Jenny Ruhl This is a different view to that of the author Dr Moseley, who quite naturally is unlikely to diss his own book. So who is right? Or do these diets impact us differently?
