I've always been slim and not eaten much. But a few years ago I started to develop a paunch! For the first time in my life, I started to check the sugar content of what I was eating. The results surprised me greatly. For example, I like chocolate protein drinks, and often have 4 or 5 per day. But the one that I liked had 10g sugar per serve. The different brand right next to it had <1g sugar/serve! So that was an instant save of ~45g sugar/day. I also had no idea of how much sugar is in orange juice. And the misleading labelling! One juice on our local shelves says: "NO ADDED SUGAR!" - but has absolute truckloads of sugar already. Results (a few months later): me 1, paunch 0!
