I have an open mind. I look forward to future studies which hopefully will investigate paleo diet vs. other diets. Unfortunately, at this time, the status of the science is less than convincing to a discerning eye. I will agree that the paleo diet can have positive effects. Now, the main point that I took issue with was the unnecessary exclusion of many foods. If you have a medical condition, then excluding or severely limiting certain items makes sense. Otherwise, it is unnecessary to achieve healthy weight loss. What has not been proven is paleo being superior to a macro-nutrient matched, fiber-matched treatment in non-sedentary adults. An obvious disadvantage of the paleo diet is the missed benefits of the omitted foods. Plenty of research shows whole grain cereals lower risk factors for coronary heart disease; dairy has been shown to improve bone health, muscle mass and strength; legumes have been shown to decrease total and LDL cholesterol. On the flip side, there is a lack of research showing that the excluded foods are harmful to the average healthy population.

I suggest that you rely on pubmed as a more credible authority for science. Starch grains have been found on tools dating to the middle stone ages, and science shows us that early Homo sapiens relied on grass seeds starting at least 105,000 years ago.
Have you ever looked into Okinawans? They are well-known for having the longest life-expectancy on Earth. While certainly many things factor into that, I think we can agree that diet plays an important part. Would it surprise you that their average white rice intake is about 3 bowls per day? The French also are known for long lives and they regularly enjoy white bread, red wine, and fatty cheese.
Of course, if what you are doing is working for you, then great, but there are many ways to skin a cat, and it has been my experience that many people who follow the paleo plan tend to be dogmatically inflexible when it comes to the banned foods and basis for excluding them.
