Step 1: Dial Back
Start by cutting down your usual intake. If you have two sodas a day, limit yourself to just one. This will help you gradually ease up on the sugar cravings.
Step 2: Re-Fizz
Artificial sweeteners in diet soda still make you want sugar, says Kristin Kirkpatrick, R.D., of the Cleveland Clinic Wellness Institute. Go for flavored seltzer.
Step 3: Add Fruit
Switch to plain seltzer and squeeze in some lemon, lime, or grapefruit for vitamin C, says Valerie Goldstein, R.D., coauthor of The Stubborn Fat Fix.
