I'd already cut out bread and cheese since I only have to look at them and the weight piles on me.
I switched to skimmed milk and low-fat natural yoghurt years ago.
I stopped using sugar 30 years ago, but I do have a teaspoon of honey every morning in my porridge.
I used to alternate porridge and home-made muesli for breakfast but I have a couple of dodgy teeth at the moment and the nuts and seeds are a problem. I used: Jumbo oats, cashew nuts, brazil nuts, almonds, sesame seeds, sunflower seeds, pumpkin seeds, raisins, sultanas, probably a few other things which have slipped my mind.
I don't have a total ban on crisps, chocolate, sweets, or biscuits but I rarely have them in the house. My niece gave me a box of chocs for Christmas and that will get shared with friends. I could easily eat them in one sitting so I won't start the box until I have company.
I don't eat meat but I do eat fish.
I allow myself to eat as much fruit/veg as I want (except for potatoes and yams which are restricted to sensible portions), since (a) it's good for me (2) it's not particularly fattening (unless it's eaten with salad cream or mayo, which I don't use) (3) it displaces other less wholesome things from my diet.
I eat 3-4 large tins of baked beans a week but I might experiment with making something vaguely similar myself (to cut out the sugar and salt). I was thinking: a tin of chick peas, a tin of chopped tomatoes, garlic, chillis, herbs and spices. Split into 3 or 4 servings.
As a matter of interest, I noticed that I'd written the date on my Saxa salt container when I opened it - 10th October 2003. I have about 100 g of the original 750 g of salt left. I'm not adding too much salt directly to my food, but some of it (such as the baked beans, and the tamari soy sauce I use) does have a lot of salt in, so I must keep an eye on how much is in my diet from those other sources.
