The last time when you tried to lose weight, what did you do ?
If you are like most people, you cut out a lot of your favorite foods, ate nothing but salads, or grapefruits and felt grumpy and deprived. Maybe you even started walking, but the drastic diet you went on made you feel worn out and about as energetic as 
a wet rag.  The better idea is too stop obsessing about every morsel you eat, and depriving yourself of the food you love. 
FOCUS on exercise. Physical activity can do more in sustaining weight loss.
If you do at least 30 minutes a day of aerobic activity for 4 or 5 days per week,
you'll lose 1/2 pound a week.
Not only taking a brisk walk, or jogging, but putting a little more spring into your household chores, taking up dancing, rollerblading, gardening, playing soccer with the kids, picking up your child 50 times a day for a hug, swimming, climbing stairs- instead of taking the elevator, joining an aerobic class.
Of course you can't expect to lose a lot of weight if you are still overeating.
Begin by exercising, then make some small changes in your eating habits.
You will be able to keep off the excess weight for good if you follow through.
Go For The Green
Try one new vegetable or vegetable recipe each week.Try a stir fry, cook vegetables in olive oil and garlic
Cut Back On The Main Dish
Cut your entree in half and double up on the vegetables and you can lose 35 pounds a year
Try The Plate Method
Half your plate should be vegetables, the other half should be divided into a serving of starch and a serving of protein. This style will fill you up on fiber and control your calories
Dress Your Own Salad
At a restaurant ask for your dressing on the side.And then use only 1 or 2 tablespoons of dressing.
Add Snacks
Cut back on the size of your main meal and add 2 small snacks.Some healthy snacks are
fruit, celery with peanut butter, lowfat yogurt or whole-wheat crackers with reduced-fat cheese
Make It Skim
Over a year you can lose 5 pounds by using skim milk in your coffee, rather than cream.

Remember to Start slowly, practice good form, aim to keep going past the first 10 minutes, walk before mealtimes, and find a walking buddy.
Think a new ways you can exercise while calling it fun.
