I truly feel for you. I won't be surprised to be in your shoes. My starting weight and goal weight is very similar. My history has been to drop four pounds and then wait. Wait. Wait. And then, boom, four pounds less. But, what an effort! One of the reasons i put my goal as low as it is. I'm really hoping to get there, but, if not because of the factor you're in now, i'll reconsider and do it in phases.
Vegaspool and I were discussing that. Along with exercise's role. He successfully kept it off and has now returned to drop to his goal. That's in my back pocket, along with really amping up the physical exercise. Doing two hours of heavy duty dance aerobics a couple times a week was the only way I've ever got my body in my own eye as perfect. Not sure i'd ever think it was worth the price again.
So, my motto is. Don't become frustrated. Know I can do this. And accept it's not all going to happen on my terms. There'a a body involved here with it's own instinctual brain. Similar to an unruly, non-Cesar Milan trained alpha dog. Trying to maintain it's own level of security. And I can only take it so far before I give out. So, maintaining a current loss beats out giving out. That's not giving up to me. It's just giving the big dog time to go back, lay down, chew on a bone for awhile. Then, I'll take up again.
Dukan's advice/choices, simply are this:
1. stop. give up. go back to old ways. regain what was lost or, quite likely, more
2. re-attack and stick with it till final goal
3. admit incapable of going further, preserve losses, go to conso
Somewhere i read his statistics for those who make it all the way. Either 20 or 80. Ha! Can't remember and don't really care. I'll be in one group or the other, but, above all else, don't want to choose number 1 above. So, knowing myself, want to leave some reserve gas in the car to make it through conso.
Good luck with whatever you choose. Just, make sure you are doing the choosing. Not the bingey, bingey, wants you to fail voice that is so good at taking over. Tell it Hush Now. Go lay down and find a bone. Or, better yet, some fat to chew on. Ha!
