I love cold sweets at night. Chocolate from the fridge or ice cream are two of my major weaknesses. As others have said, processed sugar is dangerous stuff. Lately, I've been keeping lots of fruit in the fridge. Berries, oranges, apples, etc. When I get a craving for cold sweet stuff, I'll make a simple smoothie of plain yogurt, unpasteurized honey, and fruit or I'll cut up an orange or two. Quick, simple snacks that help fight the craving. I did this a few years ago and managed to entirely get rid of processed sugar for 3 months. It felt so good! I had so much energy every day, it was incredible.

You also need to watch out for sneaky sugar. Read the labels. Just about every processed food has sugar or fat added. If it says low fat, it probably has sugar added. Things like flavored yogurt which are advertised as "healthy" can have insane amounts of sugar. Concentrated fruit juices are another bad one. While one orange is healthy, drinking the equivalent of 4 of them in a big glass of concentrated orange juice is bad. Condiments like ketchup, some salad dressings, and BBQ sauce also have crazy amounts of sugar.

If you're reading food labels and you see that something contains 20g of sugar per serving and that's 30% of your daily recommended intake, just ignore that. The gov't guidelines are very skewed thanks to special interest groups lobbying the gov't.

As you get older, your risk of developing diabetes rises dramatically. Developing good eating habits when you're younger gives you some of the tools you need to live a long and healthy life.
