Losing unwanted body weight does not have to involve prolonged workout sessions at the gym or self-defeating fad diet regimens. In fact, most people find that without a sustained lifestyle change, any weight that is lost during a period of diet or extreme exercise is gained back once the activity is no longer practiced.

If you would like to lose pounds and keep them off, then you need to invest in a lifestyle adjustment. By altering only a few important patterns in your diet and exercise routine, you can literally lose weight without much effort. Here are some tips to help you quickly drop those extra pounds:

1. Walk for 30 minutes each day. Walking is not only a stress-reducer, but it is also more effective in inducing fat loss than a 30-minute jog. Here's why: running helps you burn calories and quickly tone leg muscles because of the repeated flexing and force exerted on the leg muscles. However, because running increases the heart rate to aerobic levels, the heart rate also drops quickly once the activity has been stopped.

Walking, however, increases the heart rate to the fat-burning level. Any activity performed at the fat-burning level will have a longer-lasting impact. Thus, while you might flex and strain your muscles less during a 30-minute period of walking, the heart rate will stay elevated for a longer period of time.

2. Cut the portion in half. Whether you are eating a cheeseburger or plate of fries, divide the dish in half. If you are tempted to nibble on more than half, then give it away to a friend or have it wrapped up to take home (if you are dining out). Cutting your meal in half will not only decrease your calorie and fat in take dramatically, but it will help your body to become accustomed to smaller portions of food.

3. Get a full night's rest. Many people find, and most doctors know, that getting a full night of undisturbed sleep not only leaves you feeling energized for a new day, but it helps your body metabolize your food much more efficiently. When they body is in the resting state during sleep, it actually works much harder to process energy than if you were to sit on the sofa watching the television. Furthermore, if you are fully rested, you will be more likely to take on projects with more vigor and energy the next day (which will help you burn more calories.) So go on ? get those zzzz's.

4. Call your mother. And take care of other items on your to-do list before they pile up. Undue stress has a very negative physiological effect on the body and contributes to fat storage in the cells. By reducing small amounts of stress in your life, you can quickly and simply reduce fatty deposits on your body, especially in the stomach area. So go ahead: call your loved ones!

5. Drink plenty of liquid. Liquid hydrates your cells and helps them push harmful toxins through your body more efficiently. By drinking plenty of liquid, such as water, juice and even tea, you will help your cells function at their best without much effort at all.

If you drink tea and coffee, be aware that they contain caffeine, which can increase your metabolism while it is in your system, but tends to slow your body down once it leaves. Caffeinated beverages should always be consumed with an extra glass of water to ensure that you do not end up depleting your body of necessary liquids.

To ensure that your lifestyle alterations become lasting, practice them with friends and loved ones. Adjusting to any changes can be easier if you have a friend with whom you can share the journey and help to keep each other on track.
