6. EAT A BIG, BALANCED BREAKFAST

An a.m. meal made up mostly of carbs and protein with some fat keeps blood-sugar levels steady and hunger pangs away so you're not susceptible to pigging out come lunch, studies show. Opt for something satisfying for your stomach and taste buds — like egg whites and turkey bacon with whole-wheat toast.

7. WATCH THE BOOZE

One innocent-looking margarita or cosmopolitan can rack up hundreds of calories that do nothing to quench your appetite. Treat yourself just on the weekends and cut back somewhere else or stick to a glass of wine, light beer, or vodka and soda — three drinks that each have about 100 calories per serving.

8. HAVE FRUIT TWICE A DAY

Fruit has no fat and is mostly water, so it'll fill you up while leaving less room on your plate (and in your stomach) for high-cal fare. Don't freak about fruit's carb count — we're talking the good kind of carbohydrates that contain lots of healthy fiber.

9. STAY ASLEEP LONGER

Getting to bed just 30 minutes earlier and waking up 30 minutes later than you normally do can help you make better food choices, researchers report. Also, when you're well-rested, you're less prone to snacking out of fatigue or stress.

10. VISUALIZE YOURSELF THIN

When you feel your willpower breaking, conjure up a mental picture of yourself when you looked and felt slim. The visual motivation keeps you focused on your goal weight and reminds you that it is attainable, since you've achieved it before.
