@UpHillandDownAle it's so hard isn't it.
I didn't do anything groundbreaking really but made small changes slowly. I found that having white bread either toast for breakfast or for lunch was giving me big sugar cravings and then making me crash which in turn made me reach for more chocolate/treats. So on the most part I try not to have bread anymore.
I also started drinking coffee which I think helped me not initially reach for food especially if I was bored!
I still give myself treats but tried to reduce overall calories.
My breakfast now is one of those hazelnut filled crepes with a coffee and a banana a couple of hours later. Still feels like I've had a treat but overall that's less than 200 calories.
Then lunch I tend to have a mini tapas, carrot/cucumber/pepper sticks with a nice flavoured hummus . I also have an apple and grape fruit bag with some Brie. Again I love all of those foods and it doesn't make me feel sluggish like bread did.
If I want something more substantial I'll have some scrambled egg, bacon, mushrooms and beans which is filling too.
I pretty much have whatever I want for dinner but try and do smaller portions and eat slower but I definitely don't deprive myself if I go out for tea or go for a cake with a friend. But now instead of thinking oh fuck it I've ruined it there's no point carrying on, I'll just pull it back a bit the next day.
I feel so much better in myself and happier overall.
I also really recommend getting a Fitbit to motivate you in getting more steps if possible.
I think that's helped me a lot too.
