7.AVOID DIET SODA
Artificial sweeteners are controversial. While some studies show that they don’t affect weight, other research suggests that calorie-free drinks may cause weight gain by stimulating hunger. Dr. Shemek advises avoiding them completely. “Diet sodas set the brain up for wanting more sugar, and many people get addicted to them,” she says. Plus, ordering a diet soda can make you think you’re saving calories there, so you might as well get the mac and cheese instead of a salad.
