Hello Ms Sassi, and welcome to 3FC! Hope you find a lot of support here.
I agree with your realistic approach to weight loss, and I love the “I ate like I had some sense”-plan!

It’s like that for me too – it comes down to eating less and healthier food, keeping a food journal, teaching my self how to manage stress, and lifting weights.
Check out the “Ladies who lift forum” to find others who lift weights, btw.
Weight maintenance really is hard, isn’t it? I have lost 60lbs, but slowly: I lose weight in stages, and then try to learn how to maintain the weight loss for long periods of time. So far I’ve found that learning new and better skills for managing stress is essential for maintaining my weight loss – gaining weight because of stress eating is something I’ve done plenty of times too.
But at least you already know a lot about how you should lose weight – since you’ve already succeeded at that.
You could also check out the “Maintenance forum” where there’s a great discussion about “Thin for Life” right now – they have great discussions there.
Wish you the best of luck – hope to see you around a lot!
