Calorie swaps are good for maintenance and weight loss, but you have to continue to limit carbohydrates for weight loss. A good maintenance swap would be a Dairy Queen Hot Fudge Sundae (400 calories) instead of a Baskin Robbins Hot Fudge Sundae (800 calories). A good weight loss swap would be a no-bun chicken filet (200 calories) for a no-bun hamburger (250 calories). A good maintenance swap would be a Starbuck’s frappuccino light (200 calories) instead of a regular Frappuccino (600 calories) frappuccino. A good weight loss swap would be a 100 calorie lobster tail for a 300 calorie sirloin burger.
