One of the main keys to reaching or maintaining a healthy weight is portion control. WHEN SHOPPING: Buy snack foods that are already divided into single servings so you are not tempted by the whole bag or box. WHEN DINING AT HOME: Don’t keep your serving bowls of food on the table. WHEN EATING OUT: Ask for a take-away container when you first place your order, and put some of the food in it before you even start to eat. WHEN CHOOSING FAST FOOD: Order a kid’s meal. WHEN SNACKING: Try to avoid snacking while on your computer or watching TV.
