Hello there I'm relatively new to this paleo diet and also new to this forum! I have been reading up a lot on paleo: 1) paleo diet 2)primal blueprint 3) primal blueprint 21 days transformation 4) why we get fat and what we can do about it!

So currently i do have some questions: based on Mark's carbo curve, for weight loss we should have carbohydrates amount of below 100grams a day. As such, how many grams should my protein and fats be?
Supposing I'm 20years old, female, 5.45 feet and 112pounds. I'm quite active: I do weight lifting three times a week, and also low aerobic cardio almost everyday! How do i know how many calories i should consume and also the grams breakdown for protein and fats if i consume about 50-70grams of carbs a day?

Please do help me!! Thank you so so much
