Excessive sugar and "sweets" consumption can lead to insulin resistance and disproportionate weight gain. Do yourself a favor when it comes to beverages - Stick to pure water and seltzer. If you must have a beverage, choose 100% fruit juice and dilute it with water. You'll be amazed at how your taste buds change over time. What seems to taste fine now will soon taste WAY TOO sweet.
Hard to believe? Give it a try!
