When you are 20 years old, your metabolism is still at its peak, so compared with old persons, it is easier for you to lose weight. Such quick metabolism would enable you to just make a few small sacrifices concerning diet and fitness. If you want to lose 10 pounds in several weeks, you should try to make some simple lifestyle changes, for example, do exercises regularly, avoid having fast food, eat your food at a slower pace as well as cut down your daily caloric intake by a few hundred calories.
1. To decrease caloric intake.
It is strongly suggested that you should cut down your caloric intake by about 500 calories everyday. If you could take 500 calories less a day, you would decrease your weekly caloric intake by 3,500, equaling to a pound of weight. So in this way, you would lose 10 pounds in almost 10 weeks,
2. To have a healthy diet.
In your daily diet, you should have more healthy foods, like fruits and vegetables, whole grains and lean meats instead of eating junk food, fried foods and fast food. In addition, you should try not to have soda and juices with high content of sugar. To give up the foods with lots of fat would certainly give a boost to your weight loss.
3. To keep doing exercises regularly.
You do some kind of exercises for about 30 minutes everyday and keep doing it three times each week. It is kindly recommended that you should be engaged in kind of cardio activities like jogging, cycling or power walking so as to burn fat. As a teenager, in general you would not have serious health conditions, such as heart disease or high blood pressure, so it should be regarded as a relatively moderate fitness plan.
4. To eat slowly.
As a 20-year-olds, you must have a quite tight schedule at school or work, so you usually try to eat very fast to make time for other activities. However if you try to have at least 20 minutes to spare for a meal, you would surprisingly find that you are feeling fuller right away, because it takes 20 minutes for the brain to get the signal from your digestive tract confirming your fullness. But if you spend 10 minutes or less in having your meal, you might feel hungry quickly just after eating, which would cause you to eat more to stave off the hunger.
5.To choose your drink and dressing carefully.
You are kindly suggested to take diet soda rather than regular soda order to diminish your daily intake by 100 calories at least each day. If you flavor your salad, you had better use some lemon juice and vinegar instead of using salad dressing. You should cut your fast-food intake in half. By doing so, you could still enjoy the occasional burger while not worrying about gaining extra pounds. When you have your cereal, you should go for skim milk rather than whole milk.
