I haven't felt hungry I am mainly following the suggested menu plan at the back of the book , I have been following the 5/2 diet only eating 800 calories two days a week and only ate in the evening each day , saving the calories for my main meal , I have lost two stone on this diet , but this alone hasn't brought my blood sugar , and blood pressure down enough , just got my BMI down to 29 , I always start my day with a glas of hot water with half a lemon squeezed into it , I think it help stave off hunger pains , the book recommends going onto 5/2 diet after the eight weeks to maintain the weight loss ,
