Well done for your weight loss, fantastic achievement!
I lost 3st and have maintained pretty easily for about 18 months now.
How did you do your weight loss? I adjusted to ‘healthy eating’, stopped snacks, ate smaller portions (of normal family menu) at dinner, upped whole grains and veg, and kept breakfast and lunch healthy.
So it was pretty easy to keep those habits, while being a bit more generous with nice cheese etc. When I was in active weight loss I was very careful with celebration treats but now will not worry about birthday cake, desert after a meal out, an ice cream etc, but within my new healthier eating habits.
I weigh once a week and just go easy for a few days if I am creeping up. Not a crash diet for a few days, just hold back on extras.
Establishing a way of life was essential for me. And actually my appetite did regulate, I am now more than happy with half a pizza whereas in the olden days it never occurred to me not to eat the whole thing. I now find things I used to Hoover up far too sweet. I reached for a Kipling French Fancy the other day and then stopped because I realised that I now find them unpleasantly sweet and artificial tasting. Can still eat a whole Lindt bunny though
So I would say, if you have been calorie counting or keto or something, spend time, the last stage of your weight loss, finding a liveable way of healthy eating.
