A great little recipe that gives you the taste of eating something sweet that I like to use is as follows:
Mix a couple of tablespoons of low fat cottage cheese (awesome source of protein which will make you feel fuller and help build muscle) with a few drops of vanilla essence and one sachet of equal (or another sugar substitute), and cinnamon to taste.
Serve with mashed banana for a sweet, low sugar, low fat 'pudding'. (Really nice if you put it in the freezer for a short while to get that really cold effect. Don't knock this one until you try it, I was initially a little sceptical too. Another option is to serve with another of my 'false' sugar fixes....
Slice one apple into thin pieces with skin on (Apples contain pectin a substance that also helps you feel full). Put apple slices into microwave safe container with enough water to cover, another sachet of equal to taste, and more cinnamon too if you like. Microwave until apples are stewed. I also like my apples over no fat berry youghurt (Jalna).
I find if I can substitute for a real craving it knocks it on the head, rather than trying to eat a heap of other 'healthy' options instead.
All the best with that one
