Here's some great tips I found from Prevention Magazine:

There's nothing like a weight loss strategy that takes almost no time or effort--but still works like a charm! Here are 10 successful strategies to cut calories and burn fat that literally take 60 seconds or less.
1. Mix a juice spritzer
Combine your favorite juice (half of your usual amount) with plain or sparkling water. You can cut up to 85 calories per glass--and lose 5 pounds or more a year.
2. Walk while you talk
Burn calories while you talk on the phone: Do the laundry (68 calories), set the table (85), or water plants (102).
3. Study the wrapper
At a quick glance, that candy bar appears to contain 220 calories. But a closer look may reveal that it (or a bottle of juice, bag of crackers, or bag of nuts) provides two or more servings--which more than doubles those calories.
4. Sip green tea before a walk
The caffeine frees fatty acids so that you burn fat more easily. And the polyphenols (antioxidant compounds) in green tea appear to work with caffeine to increase calorie burn. (If you have high blood pressure, skip this tip.)
5. Pack a lunch
Dining out more than 5 times a week may make you eat more--nearly 300 calories a day--than if you dine out less frequently.
6. Dip your bread
Use olive oil in place of butter. It's healthier and may also help you eat less. In a recent study, dippers ate a total of 52 fewer calories, on average, than those who used butter.
7. Sprinkle flax on cereal
High-fiber ground flaxseed can help curb your appetite and eliminate calories. Add it to yogurt or muffin and bread mixes--it's available in health food stores.
8. Schedule a blood test
About 1 in every 12 women (most of whom don't know it) has an underactive thyroid, which can slow down her metabolism.
9. Supersize your H2O
Buy the big bottle when it comes to good-for-you stuff such as water: You'll drink more.
10. Eat a chunky salad
Chop carrots, celery, sweet potatoes, zucchini, or other veggies instead of shredding or slicing. It takes more effort to munch bigger pieces; you'll do more chewing and eat less during the main course.
