Congratulations on your weight loss.
I have lost just shy of 4 stone this year! Did it on a Low carb diet, which has totally gone to pot over Christmas! So normally I stick to low carb, no bread, rice, pasta or potatoes. No sugar. Limited fruit, half a banana ( very carby) but it is a constant battle. Need to get back to strict low carb to undo the damage after my Christmas feasting.
I weight every day, as weight fluctuates daily and if I weigh myself on a fat day, it can make me think that I have gained/STS that week, when have actually lost.
If I don't like something, I won't eat it. I no longer waste calories on "tidying up" the children's left overs. They go in the bin/or the dog. I am not a dustbin any more.
If someone dishes up something high carb, like pasta, potatoes, I will eat the smallest amount that I can and fill up on vegetables, but I can't stand PITA fussy eaters, so I will eat it, just a small portion and make up for it the following day.
Constant vigilance and I keep a pair of size 20 trousers in the back of my wardrobe, just as a reminder.
