Hello
from England.
I understand how you feel about getting so far and then life does its crushing trick, and the we let the weight back on. (For me [and this is the 3rd time in my life I've done a major weighloss] I'd lost 79lbs but have already regained so that it's now only 60, with "just" 40 to go; in my case it was fear that blood cancer had come back, I ate for comfort and it's amazingly difficult to break the binge cycle, even now that I've got the all clear).
What method did you use when you lost the 50 before? Well done on that, by the way
I'm currently trying a lowish carb way of eating which, once I eventually get into it, I've found effective. I did try a specific Diet (a UK based one called Harcombe) and, while there was nothing to criticize in it specifically, I've rejected the forum that comes with it because it was too intense for me ~ I do know what healthy eating looks like, even if I don't always do it, but I can't get into breast-beating because I ate something "wrong"..... There's a great thread on 3fc called "Carb Sensitive Dieting", where people are trying the lowish carb way and doing well. Maybe that would be worth a look for you?
