Eat at least two servings of a fruit or veggie at every meal. 3. Resolve never to supersize your food portions--unless you want to supersize your clothes. 4. Make eating purposeful, not mindless. Whenever you put food in your mouth, peel it, unwrap it, plate it, and sit. Engage all of the senses in the pleasure of nourishing your body. 5. Start eating a big breakfast. It helps you eat fewer total calories throughout the day. 6. Make sure your plate is half veggies and/or fruit at both lunch and dinner. Are there Any Easy Tricks to Help Me Cut Calories? 7. Eating out? Halve it, and bag the rest. A typical restaurant entree has 1,000 to 2,000 calories, not even counting the bread, appetizer, beverage, and dessert. 8. When dining out, make it automatic: Order one dessert to share. 9. Use a salad plate instead of a dinner plate. 10. See what you eat. Plate your food instead of eating out of the jar or bag. 11. Eat the low-cal items on your plate first, then graduate. Start with salads, veggies, and broth soups, and eat meats and starches last. By the time you get to them, you'll be full enough to be content with smaller portions of the high-calorie choices. 12. Instead of whole milk, switch to 1 percent. If you drink one 8-oz glass a day, you'll lose 5 lb in a year. 13. Juice has as many calories, ounce for ounce, as soda. Set a limit of one 8-oz glass of fruit juice a day. 14. Get calories from foods you chew, not beverages. Have fresh fruit instead of fruit juice. 15. Keep a food journal. It really works wonders. 16. Follow the Chinese saying: "Eat until you are eight-tenths full." 17. Use mustard instead of mayo. 18. Eat more soup. The noncreamy ones are filling but low-cal. 19. Cut back on or cut out caloric drinks such as soda, sweet tea, lemonade, etc. People have lost weight by making just this one change.

Eat this three-bean salad all week. 29. Don't forget that vegetable soup counts as a vegetable. 30. Rediscover the sweet potato. 31. Use prebagged baby spinach everywhere: as "lettuce" in sandwiches, heated in soups, wilted in hot pasta, and added to salads. 32. Spend the extra few dollars to buy vegetables that are already washed and cut up. 33. Really hate veggies? Relax. If you love fruits, eat plenty of them; they are just as healthy (especially colorful ones such as oranges, mangoes, and melons). 34. Keep seven bags of your favorite frozen vegetables on hand. Mix any combination, microwave, and top with your favorite low-fat dressing. Enjoy 3 to 4 cups a day. Makes a great quick dinner. Can You Give Me a Mantra that will Help Me Stick to My Diet? 35. "The best portion of high-calorie foods is the smallest one. The best portion of vegetables is the largest one. Period." 36. "I'll ride the wave. My cravings will disappear after 10 minutes if I turn my attention elsewhere." 37. "I want to be around to see my grandchildren, so I can forgo a cookie now." 38. "I am a work in progress." 39. "It's more stressful to continue being fat than to stop overeating." I Eat Healthy, but I'm Overweight. What Mistakes Could I Be Making without Realizing It? 40. Skipping meals. Many healthy eaters "diet by day and binge by night." 41. Don't "graze" yourself fat. You can easily munch 600 calories of pretzels or cereal without realizing it. 42. Eating pasta like crazy. A serving of pasta is 1 cup, but some people routinely eat 4 cups. 43. Eating supersize bagels of 400 to 500 calories for snacks. 44. Ignoring "Serving Size" on the Nutrition Facts panel. 45. Snacking on bowls of nuts. Nuts are healthy but dense with calories. Put those bowls away, and use nuts as a garnish instead of a snack.
