Hi there, I am new here, but not new to dieting.
I have tried everything in the paleo/low carb world including zero carb.
I have come to the following conclusions.
1. many people loose a lot when they go paleo because they give up sugar for the first time in their lives.
2. as above for bread.
3. paleo is good for you, but not if you eat too much fruit/nuts
4 sadly the amount you eat does matter. Like the above poster i find that as soon as I eat high carb I get hungry, however zero carb is not necessary or desirable.
So now I dont count anything...I hate counting, it ruins my life...but I dont eat much either. I had a major disaster on eat all you like as long as its paleo...it works for 20 something men only I think....but i feel so much better off sugar and grains, so i got a smaller plate and cut my portions in half. I tell myself if i am still hungry in an hour I will eat again. I never am! But I do eat paleo and I do still have cream in my tea (thank you Dr Atkins!) I don't eat any fruit, except berries in season from my own garden. This is not a hardship as i would rather eat cabbage than an apple anyday! But it helps keep the sugar down.
I hope some of this helps
