This is a long post but I hope it's helpful.
I'm slowly gearing up to start eating low carb full time. I've been doing a lot of research and reading from lots of different sources.
I would recommend the Marks Daily Apple website, I've found a lot of info on there and I think it's fairly balanced and reasonable. There are other useful websites if you have a good look around.
I'm turning to this diet because other diets haven't worked for me. I tried a traditional low calorie diet once before. It was a very sensible one that was recommended by GPs. I did loose weight at a sensible rate, however I became really ill to the point where my hair started to fall out. I couldn't understand why as I was eating more healthily then I had ever done in my life - yet blood tests showed I was severely mineral deprived.
I gave up and put the weight back on and then some after I had a baby.
I looked around and found out about the Paleo diet which I'm currently trying to get the hang of.
I had a couple of days recently of only eating Paleo plus, by which I mean Paleo plus dairy. I felt pretty good on it actually. One thing that I noticed is that it changed my hunger levels. In the past when I ate a traditional English diet, I would feel fine then have a sudden energy crash and feel hungry and very very weak.
I didn't feel like this during those days, I just felt hungry but not weak.
I wasn't on it for long enough so I have no idea about weight loss.
The big down side I've found is that for me it takes a lot of planning. I needed to make sure I had the right sort of foods in, you can't just throw a load of pasta together for a quick tea like I would have done in the past.
The consequence of this has meant that I've fallen off the wagon as I wasn't prepared for the past few days. I've gone back to eating 'normally'.
During this back to normal carb days I have felt pretty awful. My IBS which had gone during the low carb days has returned.
It's been enough to convince me that I need to go back to eating the low carb diet again.
I wish you all the best of luck.
