I am 40% Protein, 40% Fat, and 20% Carbs.

A common misconception is that eating paleo leads to weight loss... typically it does because you are eliminating foods that are calorie dense like breads, pastas, cheese and substituting with nutrient dense foods. In order to lose you will still need to maintain a calorie deficit. You will be able to eat more volume because your foods are nutrient dense and most likely not calorie dense like greens, vegetables, lean meats, etc. This will probably in turn cause you to feel full and more satisfied which will help you avoid overeating. Also, it's pretty hard to overeat when you focus on lean proteins and vegetables.

I only make this statement because so often I see paleo-ers spouting off in the main forums how eliminating grains/gluten or sugar is some magical trick that causes pounds to melt off. They also claim that they are eating more food than they ever have before. They maybe eating more food but they aren't eating more calories. Calorie=calorie, I refuse to argue with thermodynamics. You might not think you're eating in a deficit because you will probably feel more full, eating a larger volume of food plus proteins and fats are very satiating, but you are eating less cals than your Total Daily Energy Expenditure. That is the only way to lose weight.

And end of rant... welcome to paleo, the transition can be hard but it's worth it in the long run!
