These are the things that I've found useful:
- Stay away from the word "diet" and stay well away from "diet food". I don't know one slim person who eats low fat spread or reduced fat cakes!
- Understand your behaviour and be prepared to make changes to modify it. When it comes to cakes/sweets/biscuits/crisps being in the house, I have no willpower and can down a packet of biccies in 20 minutes. So I don't have them in the house. Ever. I still eat things like that from time to time, but I don't let myself view them as normal food to have around the place.
When it comes to not buying things, I remind myself that I like being slim. I don't think it's a good idea to count calories, but it helps to be aware of them. If I am struggling with the old willpower, I convert the calories in whatever's tempting me into other things - for example, I spied a good looking pudding the other day, but when I looked at the calories, it had over 800, without custard. For that many calories I could have two big bowls of pasta, which is what I would prefer. I will have the pudding at some point, but I'll wait until it's an "occasion".
At Christmas, I always used to get loads of chocolate and biccies bought for me. I used to find it quite stressful chomping my way through all of them and I'd hate gaining 1/2 a stone by January. Now I just pick out a couple of boxes of the nicest ones and give the rest away, or I'll pick out my favourite chocs from a box and put the rest in the wormery. I know this seems wasteful (and I really hate wasting food), but I tell myself that it's not really food. It doesn't do me any good to eat it, I don't even enjoy it after the first few chocs, so it might as well go.
- Try not to make a big deal out of it. I think it's counterproductive to start banning things and thinking about dieting all the time. I had a friend who was overweight and whenever we went out to eat she used to get really stressed. I remember once she threw away her whole lunch because there was a bit of butter on the jacket potato that had melted around the plate. After a hungry afternoon, she bought a coffee and walnut cake on the way home and ate virtually the whole thing. I think this is a pattern quite a lot of people end up falling in to. Go for a curry/meal when you want to, have a slice of cake when you go for a coffee and never ever feel bad about it.
I also think it helps to see "treats" as a social thing. I wouldn't sit on my own and drink a bottle of wine (well, not often ), so I wouldn't do the same with a packet of biscuits.
- Make exercise part of your everyday life. I don't have a car, so I walk everywhere, generally between 40 minutes and 3 hours per day. A 40 minute walk to work instead of a 15 minute bus ride soon makes a difference if you do it every day, and doesn't take that much time out of your day.
Blimey, that post was longer than I thought it would be!
