My family has been on the paleo diet similar to Robb Wolfs Paleo Solutions. My son has lost 20+, my daughter-in-law 20+ in first month, myself over 10+ but did not need to loose much more. My wife is battling diabetes and this is the only thing keeping her Blood Sugars in check and not gaining weight. We all feel much better with more energy. The science behind it solid and it really works if you make it a habit. It takes some time and effort in preparing your food and you just can’t roll through a fast food joint or restaurant. In Robb’s book the Paleo Solution he gives you a month of foods and recipes that if you try it you will see results. Of course you still need some exercise but that is second to the diet. Keep up the efforts it will be worth it.
