Weight Control: The Power of Healthy Choices

What Is a Healthy Weight for Me？

This is a tough question to answer. Even though many people talk about weight, what really matters is how much of your body weight is fat. The body mass index (BMI) is an approximate measure of body fat. It is based on your height and weight. A BMI between 19 and 25 is considered a normal amount of body fat. If someone's BMI is 25 to 29.9, that person is said to be overweight. A person is said to be obese (过度肥胖的) if his or her BMI is 30 or higher. The higher your BMI is, the greater your risk for diseases such as diabetes, heart disease, arthritis, and certain cancers is.

Some Causes That Can Lead to Being Overweight

Having weight problems in your family.

Eating when you're lonely, sad, bored or stressed.

Eating because you feel pressured by friends or family to eat.

Using food for recreation, or eating just because food is available.

Taking medicine that makes you feel hungry.

Having hormone problems that slow your metabolism (how fast your body burns calories).

How Can I Lower My BMI？

The best way to lower your BMI is to reduce the total number of calories you take in and to be more physically active.Long-term success is not about finding the "right" diet. It's about identifying your behaviours that have contributed to taking in more calories than your body needs. It is also about making a plan to develop healthier eating and physical activity habits. For example, you may eat when you're under stress rather than when you're hungry. Choosing another activity to do when you feel stressed, such as taking a walk, may help you break the habit of eating at those times.

You're more likely to make changes in your habits if you set a specific goal for yourself. For example, instead of saying "I'm going to lose 20 pounds", decide that you'll be more active every other day of the week. Be specific about what kind of activity you'll do and which days you'll do it. Your new goal might be: "During my lunch hour on Mondays, Wednesdays and Fridays, I'm going to walk for half an hour in the park." Once your new healthy behaviour becomes a habit, you can move on to another goal.

Why Is Physical Activity a Big Deal？

Physical activity builds muscles, so even if you don't lose pounds, you will look and feel better when you are more active. Being active also reduces your risk of chronic diseases like heart disease and diabetes, even if you are overweight.

What Is the Best Kind of Activity？

First, ask your family doctor if there is any kind of physical activity that you should not do. Being more physically active doesn't mean you need to have a formal or complicated exercise program. Remember that the best kind of activity is the kind that you'll keep doing. Whatever activity you choose, try to do it for at least 30 minutes per day on most days of the week.

Aerobic exercises, such as swimming, walking or jogging, raise your heart rate and help burn calories. The longer you exercise, the more fat your body will burn. Walking can be very helpful even if you don't walk fast.

Light weight training also has many health benefits. It helps add muscle mass to your body. Muscle burns calories faster than fat does.

How Can I Change My Eating Habits？

Change them one at a time. For example, start by training yourself to eat without doing anything else at the same time.Focus on enjoying the taste and smell of your food by eating more slowly. Don't watch TV, talk on the phone or drive a car while you eat.
