Eat lean meat AND fat meat. That's what humans used to do. Add veggies, tubers, fruits, nuts and maybe seeds, cheese, wine and chocolate. Skip the muffins, breads, cakes.
You can make a good paleo muffin/cup cake out of an egg, a generous heaping spoon of almond butter, a banana (or a half a large sweet potato already cooked, or an equivalent amount of canned pumpkin) and a big spoonful of unsweetened cocoa powder (or pumpkin pie spices). Mix together, put in a coffee mug and microwave for 2 minutes. Dress up with whipped cream, melt squares of chocolate in it while it's microwaving, or drizzle honey all over it. Yummy!
