Use a smaller plate so your plate will look full but will have less food than if placed on a plate larger than 9 inches.
Fill half your plate with lower calorie, low carbohydrate vegetables (salad greens, cucumbers, celery, green beans, bell peppers, etc.). Low carbohydrate vegetables will contain only 5 grams of carbohydrate/serving.
Sip on a broth based vegetable soup before your meal. A broth based soup is considered a low calorie free food since it contains less than 10 grams of carb per serving.
Eat a salad before you start eating your meal.
Portion out foods like nuts, crackers, and cereal into small plastic bags instead of eating out of the box. This will help you control the amount of food you are eating.
