My experience since eating the Atkins way or similarly since 1972:

Losing the weight is the easy part. Maintenance is harder. Please note that this is the first time in my life that I've maintained my weight loss. Before, I'd lose the 30 lbs The Same 30 Pounds and then quickly gain it back. The gaining back for me went much quicker than the losing. That old axiom about "losing slowly" didn't work for me.

I'm currently doing much self experimentation (n=1). The Science of what is going on inside my body is different from everybody else. I need to ascertain what my body needs to stay healthy and mobile and maintain my weight loss.

My advice is based upon my own experience. While you're losing, try to figure out the Science of why you're losing, how much is water weight, how much is fat loss. Dr. Jason Fung has the best explanation for all these things and you don't have to buy a book to find it, just go to his blog. It's all there. The search feature on the site is very good.
