One good way to lose weight is to simply stay so busy that you don't have time to eat! When you have nothing to do, you think about eating food and crave a snack, just because it's an activity to do. It is important to keep yourself busy to prevent this from happening so you can be successful.
Literally pay attention to what you are eating. Do not multitask and eat at the same time. If you are watching television while you eat, chances are you are not paying much attention to what you are putting in your mouth. Instead, sit down and have a nice meal at the dinner table.
Try giving yourself an incentive to lose weight. If there's a DVD or video game or other object you want, make it a present to yourself. If you meet your weekly/monthly goal, you can get the item you desire. If you don't meet your goal, you don't get it. That'll give you an extra boost to work hard.
A way to really motivate you to lose weight is to join an online weight loss group or forum. You can make friends online that will help motivate you to stay on target! You can also learn a lot about other people's experiences in weight loss and possible tips to stay on track.
