along the lines of what Myles said, one anesthesiologist buddy of mine (who BTW climbed Everest) said to me that the reason there are so many diets in the world, is that none of them work
IMO what Bill did may have been called Paleo but looking beyond was rather more a life style change that resulted in the weight loss over 1.5 years
I hooked up with a nutritionist 3 years ago and began a strict diet and exercise program resulting to date in a 63 lb weight loss which I have maintained
I agree with Frantz that "good" fats in one's diet is essential. I would also go so far as saying that we also need a small amount of saturated fat each day (such as a tablespoonful of butter)
Unlike Frantz, I do believe that milk is essential. I just drink non fat or on rare occasions 1 % milk.
I also found that reducing the frequency with which we dine out was a huge help.
Good for you. I think you are right, it's not really accurate to say what i am doing is "Paleo" or just the result of diet. I think sensible food, clean, non-processed, etc. combined with consistent, effective exercise is the key. There is also so much sugar in stuff. I won't drink OJ other than fresh- even the fancy stuff seems to be full of sugar. Likewise, salad dressings. Ton's of salt in restaurant food.
And I drink gallons of water.
