I have just bought the Jason Vale book on juicing lose 7lbs in 7 days but there seems to rather a lot of pineapples and high sugar fruit in his recipes, I thought it was going to contain more green juicing recipes (ie vegetables). I am now worried if all the fructose will put my sugar levels up or will it be ok as not taking in any other carbs. Has anyone followed this or similar diet and how did it affect their sugar levels. Before anyone says I should try other diets first, I have and have lost 4 stone but have not been able to lose any more in past six months and still need to lose another two stone.
