Low fat meal options, or small portions of ‘normal ‘ food, use a smaller plate.
No snacking, 1 small potato per day, 1 slice of bread, obviously no sweets, biscuits or cakes.
Start a hobby so there aren’t too many idle moments when you are bored and want to eat, if you feel hungry have a glass of water and only eat at meal times.
There are many thousands of low fat meals online if you want to cook.
Move around more!
I stuck a couple of photos of myself on the fridge door, I’d been very unwell many years ago , had a big op and didn’t recognise myself in a family wedding photo! That did it, I was horrified and I’d lost the weight in a few months and ripped up the photos.
Although I’d like to weigh less I’ve been stuck at 10 stone for a long time, it’s my fault though, I should follow my own advice!
Good luck.
