4. Resolving to follow the latest fad diet
Fad diets, diets that require you to purchase special food and plans that require you to cut out certain food groups altogether often end up with you right back where you started on the scale. “Stop yo-yo dieting, because eventually your metabolism will conk out from all the up and down and it will be harder to lose weight,” says Joey Shulman, a registered nutritionist. Instead, choose a diet program that works for your lifestyle and work the best parts of it into your routine—even after you’ve lost the weight.
