I know there are others of these books out there, but this author has written a very easy read version. A little science, a lot of inspirational snippets from those who are already trying the diet, and very easy to understand and put into practise. Yes I am trying this diet after many (and I mean MANY) years of all the failed diets under the sun! This is super easy, super affordable, and is great for re-training your brain even on your ‘feast’ days! You have gotta grab this…it's cheap and its very easy to just start straight away. Two thumbs up!
