Query: It works for 50+ women

If you are older and have the sheer will to stick to an eating plan, choose this one. I thought I'd never be able to lose weight again, but as tough as this diet is, it got results right away and--although I was totally skeptical--it does stop your cravings for sugar and salty snacks. I don't claim to understand how, even after reading the book twice. I'm guessing it has something to do with flax seed oil. And the food sensitivies the book refers to really do show up. You learn by experience which foods will give you bloat, gas and make you sleepy. Best for me besides the 5 pounds lost in 5 weeks (I had 20 exremely stubborn pounds to lose)was I have stopped retaining water which you can see in my ankles and hands. I'm being honest when I say I will probably follow this healthy plan for life. (The book needs a better index. You refer to it several times a day if you're like me.) I am going to get the recipe book now.
