High-tech ways to lose weight
ONLINE RESOURCES DETAIL FITNESS PLANS

I hate to break the news but using a computer or playing video games doesn't qualify as aerobic exercise. The good news, however, is that technology can play a role in helping get family members into better shape. There are plenty of online resources that can aid in a diet or fitness plans as well as electronic gadgets that can help you monitor your progress.

 I speak with experience -- I've struggled with a weight problem my whole life and -- several months ago -- decided it was time to lose weight and get myself into better shape.

I signed up for eDiets.com, which offers online diets, recipes, fitness plans, expert help and support groups. The concept appealed to me because it provides the human interaction that I need to get motivated. The service, which costs $10 a week or $99 if you sign up for a year, provides you with the same type of information that you'd get from a dietician or a walk-in weight loss program. Because it's online, you don't get the in-person interaction you would receive from Weight Watchers or any other off-line program.

I wish I could give you a fair evaluation of the service, but I didn't stick with it for reasons that have nothing to do with the quality of what they offer. In fact, the more I learn about weight loss, the more impressed I am about their approach, which helps dieters develop an individualized plan based on their needs and preferences. Instead of dictating an approach, it respects a variety of proven weight loss options including ``low fat/low cholesterol,'' ``Low sodium'' and ``low sugar'' diets. Unlike many fad diets, it encourages gradual weight loss and offers programs that support vegetarians.

Although I have no complaints about the service, it wasn't for me. I need hands-on help. I think it has something to do with having to report to an ``authority'' figure.

So, after half-heartedly experimenting with eDiets, I came across an advertisement from Stanford Medical Center's General Clinical Research Center seeking volunteers for a weight-loss study. The study had me follow a diet that was moderate in carbohydrates and protein with some extra helpings of unsaturated ``good fat'' from sources like nuts and avocados. The diet, along with daily bicycle rides, worked for me and I'm now about 35 pounds lighter and feel much better. You can get all the details at www.pcanswer.com/diet. That Web page will also provide you with links to all sites mentioned in this article.

Even though my diet program included weekly visits with a dietician, I still made much use of technology. Like many diets, the Stanford Study had me keep track of food exchanges rather than calories. I was allowed a certain number of daily servings of starch, protein, fat and carbohydrates, which I tracked using an Excel spreadsheet. I also used Word to create a little wallet-sized record keeping card which I printed out on blank business card stock. And, when I needed information about a food's nutritional values, I consulted the free online USDA Nutrient Database (linked from www.pcanswer.com/diet).

There are also plenty of online resources that can help you determine whether you or family members need to loose or gain weight. eDiets, for example, offers a free assessment profile that asks your height, weight, age and gender and gives a proposed ``goal'' based on your current weight and healthy weight range.

It bases the healthy weight range on what is called your `body mass index or BMI, which is calculated based on your weight and height. A BMI of between 21 and 25 is considered good, 25 to 30 is overweight and 30 or higher is considered obese. You can also find an easy to use BMI calculator at www.nhlbisupport.com/bmi.

Although there are those who argue that ``calories don't count,'' most experts I've spoken with agree that 3,500 calories equal a pound of fat. Reduce your intake by 500 calories a day, and -- over time -- you'll lose about a pound a week. Your first step is to know approximately how many calories it takes to sustain your weight which, of course, varies depending on your age, gender and activity level. You can get a pretty good idea at http://techware.com/health or, if you want a more precise estimate, you can enter your specific activity levels at http://stevenscreek.com/goodies/calories.shtml.

The National Institutes of Health estimates that at least one in five children are overweight and has put together a resource page at www.niddk.nih.gov/health/nutrit/pubs/helpchld.htm. There are additional fitness and nutrition resources for kids and teens at www.kidshealth.org.

Diet, of course, is only part of the weight control equation. Burning calories through exercise, not only takes off weight but improves your overall health and conditioning. But do the number of calories you burn from that 15 minute walk make up for an extra piece of pie? You can get the bad news at www.healthstatus.com/cbc.html.

Speaking of exercise, you should aim for a target heart rate which, according to the American Heart Association, is calculated at 50 percent to 75 percent of your maximum heart rate that is generally calculated as 220 minus your age. You can find a heart rate calculator at http://my.webmd.com/heartrate.


Polar A1
Heart Monitor

One way to keep track of your heart rate during exercise is to measure your pulse for 10 seconds and multiply by six. If you want a high-tech solution, consider an electronic monitor that measures your heart rate continuously. You can spend several hundreds dollars for one with all sorts of complicated features but I got a basic model -- a Polar A1, which is cheap, easy to use and just as accurate as the more expensive models. You can find it online or at local sports stores for between $50 and $69. The monitor itself straps to your wrist like a watch but you also have to wear a light weight plastic band around your chest that transmits signals to the watch.

Regardless of the Web sites and gadgets you employ, your ultimate challenge is not only to develop a reasonable diet and fitness plan but to stick with it after you've taken off the weight. That goal -- regardless of my recently reduced body mass index -- is something that I don't take lightly.
