I've inadvertently lost a lot of my taste for sweet food because I started Weight Watches in November and of course have been watching what I've been eating a lot more (things sort of went a bit off the rails for Christmas and New Year admittedly).
However I now find that I can quite easily look at the dessert menu and not have any major desire to have anything, and I never have any interest in buying cakes or biscuits when I'm shopping. I still have a small hankering for chocolate, but I will just have a very small piece and be satisfied, unless of course someone sticks a whole block under my nose..lol...
Here's a little tip I've picked up from WW. If you really feel you need a sugar/sweet hit, get some pumpkin, cut it into pieces and roast it until it's really soft and sweet. You could add things to it like garlic, rosemary etc if you want to, but I prefer mine "straight with a twist of salt". Anyway, leave it in a container in the fridge and just have a couple of small pieces when you feel like it. It is so lovely and sweet, and under the WW points system it is totally zero points, and totally guilt free.
