Most who lose weight will regain. The vast majority. FACT.
What do those who keep it off do right? Here's one article addressing that.
See the book THIN FOR LIFE to see several people who lost and kept it off. And how they do it. And the Google Books preview lets you read a bit of the book, including the list and explanation of the TEN KEYS that the "masters" use to keep it off.
Books aimed at maintainers--Previously Overweight persons--are not numerous. At least, I sure haven't found a whole lot. Back in 2010, when I was looking for maintenance success and maintenance related stuff to prep myself--yes, I wanted to see how they did it, believing I'd get there one day--pretty much it was REFUSE TO REGAIN, THIN FOR LIFE (that I owned since the first edition), and JOINING THE THIN CLUB (which, really, I didn't like much, and certainly didn't value or reread like I did the other two I've mentioned.)
Refuse to Regain has 12 rules. Thin for Life has 10. I like lists. :D
Blogs with successful maintainers include Roni's Weigh, Keeping Off 200 Pounds, Keeping the Pounds Off, among several excellent ones. (See my blogroll, sidebar right, for some links.)
Among my fatfighting pals, Karen of Sunshine's Heart and Anne H of Carb Tripper are also maintainers out there, working it, learning, adapting, fighting the fight.
I hope to feature some of the "masters" at maintenance--those at a stable goal weight for several years-- in the future. I'm thinking I may beg them to let me interview them and feature interviews. Me, baby, I'm interested in the folks GETTING IT DONE! I want to learn from MASTERS....
