I feel like the paleo diet is probably pretty good for people who want to lose weight and build muscle. It allows for tons of protein and fats, while mostly eliminating carbs. That will usually result in weight loss for the average person, and if you're lifting simultaneously it should help with that as well. I don't see any point in eating anything raw though. There's just nothing to be gained there IMO. There needs to be a reason for everything you do in a diet. High protein and fat with few carbs has a definite and readily evident beneficial aspect. Undercooking things doesn't. To me that means it's probably garbage that people latched onto thinking that if a paleo diet was good, then taking it to the extreme would have to be even better. It isn't.
Some of my favorite recipes are apparently paleo compliant. Kalua pork for instance is some seriously good stuff. It doesn't appeal to me to adhere to any specific kind of diet though. I like sweets way too much for that. So called "flexible dieting" serves me much better. The two numbers I worry about most are calories and grams of protein, after that I try to keep fat and carbs as balanced as I can. This is better for me because I can still achieve all my goals while maintaining much better adherence to the diet than I could with a stricter system. I can actually "cheat" without cheating, for instance. I can eat literally anything at any time so long as I keep track of it and make it balance out in the long run. Binges, no matter how egregious, are never seen as insurmountable irrecoverable breaches of my diet. It's just better for me.
