A positive attitude is very important for successful weight loss and weight management. To lose weight permanently, you must make a commitment to gradually adopt a healthier way of life.
You can control your weight. To lose weight, you must eat fewer calories or burn up more calories than you need. The best way to lose weight is to do both.
Following a very low calorie diet can leave you feeling deprived and can increase the temptation to binge. Often, very low calorie diets make you lose muscle instead of fat. You are then left with a body that jiggles instead of one that is smooth and toned. Exercise helps you keep the muscles and lose the fat.
Very low calorie diets also lack many important nutrients, putting you at risk of becoming malnourished. Most importantly, research shows that people who follow these diets usually gain all their weight back. People who lose weight slowly by eating less and exercising more tend to keep the weight off.
Determine your BMI
There are several ways of measuring your ideal body weight. One of the most popular methods to gauge whether or not you are overweight is the body mass index (BMI). The BMI uses a mathematical formula that measures both a person's height and weight in determining obesity. To calculate your BMI, multiply your weight by 703, and divide the answer by your height in inches. Divide this figure by your height again.
(Weight in Pounds x 703) / (Height in Inches) = BMI
For example, a 250-pound person at 5’10" would have a BMI of 35.86. People with BMIs of 25 and above are considered to be overweight. Having a body mass index over 30 places you at risk for developing obesity-related medical conditions such as diabetes, high blood pressure and coronary artery disease. A BMI over 40 indicates that a person is morbidly obese.
How many calories do I need?
Everyone's energy needs are different, but there are ways to estimate how many calories you need. One easy method is based on your activity level. Decide whether your activity level is low, moderate or high. Pick one of these definitions:
Low -- You don't participate in any regular physical activity, or you are involved in recreational activity only on the weekends.
Moderate -- Your physical fitness program includes aerobic activity for 30 to 60 minutes at least three times a week.
High -- You exercise vigorously for 60 minutes or more at least four times a week.
Next, find your activity factor by using the chart on the right. Look for the number where your activity level matches your weight status. Multiply this activity factor by your weight to estimate how many calories are needed to maintain your current weight.
To lose weight: Subtract 250 calories to lose 1/2 pound per week. Subtract 500 calories to lose 1 pound per week
|Low Activity||Moderate Activity||High Activity|

Making every calorie count
The Food Guide Pyramid is an excellent tool for making sure you are meeting your nutritional needs while trying to lose weight. With the proper balance of foods, you can lose weight and improve nutrition. For an online resource, go to www.mypyramid.gov.
One way to ensure that you are eating healthy is to keep an accurate food journal. Write down everything you eat and drink, including serving sizes/portions. Be honest and accurate, otherwise the journal is not helpful. Keeping a record will help you learn about your eating habits and help you assess the food choices you make.
Putting it all together
In addition to changing your diet, mildly restricting calories and keeping track of what you eat, it is very important to include exercise as part of your weight loss and weight maintenance efforts. Discuss with your physician what is the best exercise for you, but make a point to exercise.
Presidential Sports Award
The Presidential Sports Award program was developed by the President's Council on Physical Fitness and Sports in 1972 in conjunction with national sports organizations and associations. The purpose of the program is to motivate Americans to become more physically active throughout life. It emphasizes regular exercise rather than outstanding performance. It is important that participants over the age of 40 who have not been active on a regular basis undergo a thorough medical examination before undertaking any physical activity program.
The challenge of the Presidential Sports Award program is for Americans to make a commitment to fitness through active and regular participation in sports and fitness activities. Earning the award means that an individual has put in time and effort to meet the challenge of personal fitness. The award recognizes this achievement and the fact that the individual is part of a nationwide effort toward a healthier, more vital America.
Awards can be earned in any of numerous sports/fitness activities--such as roller skating, bicycling, dancing, swimming, walking, golf or t'ai chi--and individuals can earn as many awards in as many categories as they like. See www.presidentschallenge.org for more information.
Some things learned to date:
Those who have achieved successful weight loss report making substantial changes in eating and exercise habits in order to lose weight and maintain their losses. On average, registrants report consuming about 1400 kcal/day (24 percent calories from fat) and expending about 400 kcal/day in physical exercise. Walking is the most frequently cited physical activity.
The average registrant has lost about 60 pounds and kept it off for about 5 years.
Two-thirds of these successful weight losers were overweight as children, and 60 percent report a family history of obesity.
About 50 percent of participants lost weight on their own without any type of formal program or help.
Successful weight losers appear similar to normal weight individuals in terms of resting metabolic rate.
