Vegetables are a great source of phytochemicals, fiber, water, vitamins and minerals. Vegetables themselves are naturally low in calories and are usually very helpful in weight management or in losing weight. The trick is to not prepare them in high-fat ways. For example, adding butter, cheese, creamy sauces, high-calorie salad dressings, or deep-frying vegetables can add significant calories. When your total daily caloric intake exceeds your needs for the day, you can certainly gain weight. Instead, work to prepare your vegetables in healthy ways: try sautéing them in a small amount of olive oil with garlic, add herbs and spices or freshly squeezed lemon for complimentary flavors, use light salad dressings, have vegetable or tomato-based soups instead of cream-based soups.
