Are you a night owl who sometimes gets the midnight munchies? It's okay to add a late-night snack to your meal plan, particularly during Phase 1 of the program when you're still getting your hunger and cravings under control. Frequent snacking can help stabilize your blood sugar and insulin levels, according to Dr. Arthur Agatston, leading preventive cardiologist and author of The South Beach Diet Supercharged. Here are some tasty late-night snack ideas, suitable for all Phases:

• Celery sticks with hummus or natural, no-sugar added peanut butter
• Raw veggies
• Lean deli meat roll-ups
• Part-skim mozzarella cheese stick
• Nuts such as almonds, peanuts, or pistachios, but stick to one serving — about 15 almonds, 20 peanuts, or 30 pistachios — since too many nuts can impede weight loss
• Fat-free or 1 percent cottage cheese with salsa or chopped cucumber
• Dry roasted or boiled edamame (green soy beans)
• Fat-free or 1 percent milk
• Plain nonfat or low-fat yogurt
