At the moment and as part of a weight loss plan, I eat snacks of celery, carrot, pepper, radish, baby plum tomatoes. These obviously require some prep, so I cut up a mix of these in the morning for PM snacking.
If I really want something sugary I tend to go for a rice cake or 2 with the whole earth peanut butter on, no added sugar and reasonably low in oil too. Either that or some 74% Tesco dark chocolate with some pecans or walnuts.
I still eat biscuits too often as well but they are on both floors at work and free, plus I have very little will power so I find them hard to avoid!
Good luck at coming off sugar, I’ve not managed it yet, but I am about 2 stone lighter so far this year.
