Wow, this post unleashed a myriad of thoughts. First, I thought, wow, I'd be really pissed if I yoyoed 50 pounds after cutting my body apart because I so like being a little thing for the first time in my life (though my BMI is still 23 to 24) and skinny jeans are so awesome. Then, I thought, wait a min. I weight 135ish and my diabetes is gone and I would have been so happy at 185 and no diabetes and still thankful every day for the DS. Munchkin, I hope you get to weigh you want to be one day and it's easy to keep off, but I'm happy you are healthy and wishing you the very best.
As for the regain, I'm just 23 months out, so I'm not sure what will happen. I did bounce up about 5 pounds at month 19 and took it off. But, I assume I will struggle a bit in the next year. I don't want to weight above 140.
I don't eat enough to really weight much more than I do I suspect. I eat about 1200 calories a day. If I eat more fat, which some days I do, it goes right through me. I never eat more than 400 calories of carbs a day.
