Agreed and I have read some stuff on the paleo and it makes sense. The problem is, I have been doing it a differnet way for 2 years and feel great. So I may try to incorporate some paleo like eggs and butter. I also like the idea of shorter cardio sessions
I don't think it's a problem that you feel great.

The paleo diet works for a lot of people, but it's not the only diet that works. It's overly restrictive for people who tolerate grains, dairy, and legumes well. But being overly restrictive might be
why it works well for many people. First, it's a godsend for people who really don't tolerate grains well (but hadn't realized it). And second, psychologically, I think compliance is made easier for many people if certain foods are taboo. "Everything in moderation" makes it easy to rationalize a cheat at any given time, which for some people means that the "moderation" part is dead-on-arrival. By making all grains off limits, period, there's no way to rationalize eating a Ding-Dong. People may still cheat, but without being able to rationalize it so easily, it should happen less often.
Finally, if you look at the foods that really wreck a lot of people's diets by causing them to binge — donuts, Doritos, Oreos, etc. — most of them are highly-processed combinations of vegetable oil, wheat flour, and added sugar and/or salt. Paleo seeks to avoid all of those except for salt (unless you follow Loren Cordain, whose plan does restrict salt). So while avoiding all forms of wheat flour, including all bread and pasta, may be overkill for some people, it has the benefit of making the worst junk foods taboo, and therefore aiding compliance when it comes to avoiding the worst-offending diet-wreckers. (With any diet, compliance is obviously the key.)
In any case, for people who tolerate grains well and don't struggle with compliance in avoiding junk food, I don't think breakfast cereals or bran muffins will prevent them from being healthy or feeling great.
I think a decent overarching principle is: if you want to eat healthy, find a culture renowned for the health of its people and emulate their diet.
Our paleolithic ancestors were quite healthy compared to their neolithic descendants, so the paleo diet is one example of that principle in action; but it's not the only example. To pick a highly contrasting dietary tradition, the Swiss mountaineers of a century ago were famous for their hartiness and health, and they subsisted mainly on rye and dairy, both of which are excluded from a true paleo diet.
In other words, I think it's hard to go wrong with a paleo diet; but it's also hard to go wrong with a traditional Swiss diet, a traditional Okinawan diet, a traditional Mediterranean diet, a traditional Inuit diet, etc., etc., etc. All such diets have certain features in common, however, such as eschewing modern American junk food.
