Diet questions go in the Diet section. One of the mods can move this easy enough.
I eat paleo as much as I can. I'm not completely strict, mostly because I'm not the only one in the family and I eat in the cafeteria a lot. The reduced carbs does make a difference to my fat levels and the high nutrients in the food makes a difference in my health. Once you realize that grains are a complete waste of calories, this becomes an easy way to eat. Whole grains are only good for people that are stuck on white bread. Grains are empty calories regardless of how unrefined they are. Starchy carbs are close to grains in their emptiness. They have very few nutrients compared to better foods. The hard part about paleo is getting enough calories and that's where meat comes in. I think at least half your calories should come from animal sources. Ideally 3 meal a day based on eggs, fish and meat each day. I tend to go with 2 egg meals just because it's the closest to paleo I can get at the cafeteria.
I know your pretty much the most knowledgable paleo member who posts on here...how big of a part can nuts/seeds be? Or to a lesser extent beans? If I have a large portion of cals based on nut/seed fats...as opposed to dairy fat or carbs...that's not gonna derail things is it? My stomach gets upset too easily with fatty meats like beef and pork.
I think nuts, beans and seeds are OK in moderation. They have a lot of carbs and the nuts and seeds usually have a fair amount of O6. However, O6 from whole foods seem to be better for the body than processed oils so I wouldn't worry too much about them. If you're trying to gain weight, I wouldn't worry too much about the carbs, you need the calories. I used to snack on nuts fairly often but lately I don't get hungry between meals much so I don't so much. Beans and chili go together so well, I don't know how you could cut them out completely. That's just not human. If you're trying to lose weight, be real careful with these.
