I'm getting back into regular exercise after a few years off from having dc's, and hoping to build up to some events like a 10k run. I walk as much as possible to/from Dc's nursery and activities, and exercise 2 or 3 times a week. I'm hideously addicted to sugar so trying to break out of that trap as well as eat better to help me exercise more. Can I please have some ideas for more healthy snacks that will help fuel my body? I've been looking up protein shakes but they're so expensive I'm not sure if they're worth it. I used to use carb based sports drinks when I was training before dc's and am wondering what the best option is now.
