BMI calculations might seem like some esoteric and complicated process that you have no hope of figuring out. That’s not true. BMI isn’t magic or some scientific secret withheld by those in the know. If you’ve ever used a BMI calculator online, then you know that you put in your height and weight, and it cranks out special number. There’s always a chart handy, or the website interprets it for you, and tells you whether you’re underweight, normal weight, overweight or obese, all based on this single number. The website did the calculations for you, but you might be wondering just how it arrived at that number. BMI calculations are fairly simple once you understand the basic formula. But first, let’s look at what BMI is and what BMI calculations are used for in the first place.

BMI is the measure of body mass. By comparing your weight and height, specifically dividing your weight by your height, squared, the BMI calculations give us a single number. Depending on where that number falls on a special scale, it tells you if you’re underweight for your height, in the normal range, overweight, or obese.

BMI doesn’t measure body fat, however, so often the number is wrong when it comes to athletes or very muscular people. Muscle weighs more than fat, so for them, BMI isn’t an accurate measure at all. For most people, though, it’s a very good estimate of weight in relation to height. So what BMI calculations allow us to arrive at that magic BMI number?

BMI calculations may seem complicated, but they’re really not. At its most basic, the formula is kg/m2. Or your weight in kilograms divided by your height in meters, squared (your height in meters times itself). A person who’s five-and-a-half-feet tall stands about 1.7 meters. Square that number (1.7 times 1.7) and you come up with 2.89. A person who weighs 150 pounds weights about 68 kilograms. So the BMI calculations to determine this person’s BMI would be 68 divided by 2.89. The result of that is about 23.5.

A BMI of 18.5 or below indicates that an individual is underweight. The normal weight range is from 18.5 to 24.9. Overweight people will calculate a BMI of 25 to 29.9. A BMI of 30 or greater indicates obesity. So a person with a BMI of 23.5 is within his or her normal weight range, according to the BMI calculations.

If you don’t want to convert feet and pounds to meters and kilograms, then you can use one of the other BMI calculations to figure your number. This person’s new formula would be weight in pounds, 150, times 4.88, or 732, divided by height in feet squared (5.5 times 5.5) which is 30.25. Then divide weight by height squared (732 divided by 30.25) and the result is 24.1, very similar to the metric formula’s result. BMI calculations can also be done by taking weight in pounds times 703, and dividing by height in inches, squared.

Teens do experience what we could call “teenage weight pressures.” At the age of 16, teenagers are still too self conscious of their appearance that they are easily affected by jeers by classmates and peers when it comes to how they look. Being stereotyped because they are a little overweight can be really demeaning which could cause other personal or even psychological problems later on.

But the thing is, if a teenager has been eating and exercising right their bodies will be where they should be at their age. And when teenagers find themselves overweight, impatient as they are, they tend to go overboard often taking the drastic route to loose weight. They try skipping their meals or limiting food intake the wrong way.

Because teens and preteens are still growing, the practice of skipping meals is not such a great idea. Even adult weight loss programs do not arbitrarily recommend skipping meals. The right diet is eating the right food that covers teenagers’ nutritional needs for their body’s further growth and development.

More often than not, dietitians recommend that teens follow an eating plan that will help reach their ideal weight and keep it there. They complement food diets with lots of physical activities. They find that cutting back on calorie intake is not the best option for teenagers to take. Being effective “calorie burners” seems to be the right path that teenagers should take. By exercising a lot they will reduce body fat and build their muscles at the same time.

As teenagers, they should also be encouraged to try all types of sports. By increasing their physical activities they will develop tons of energy as well as strength and stamina. Their bones will grow better and stronger. The will have better and healthier skin and will have a general happy outlook in life.

However, for some teenagers a customized diet program is needed and is suggested to be the most effective. But this is in a case to case basis. Not all situations and circumstances are alike. These diets are normally designed by diet and nutrition experts. Included in these customized diet programs are itemization of particular food groups and proper proportion you child or teen should eat.

These diets focus on reducing the intake of foods loaded with saturated fats. Reducing fat in one’s diet will make him/her healthier and will make it easier to maintain their body weight. Under these programs, daily food consumption should not have more than 30 grams, or 10 ounces, of fat.

You need to, therefore, spread out your intake of fat for each meal if you eat. It is generally recommended that persons on a diet should avoid fat laden snacks like potato chips or buttered popcorn.

In your teen’s eating habits, probably the biggest obstacle that they will face is when they eat at restaurants or dinners with friends. Foods in restaurant are served in big portions and more often than not contain too much salt, fat, and calories. Part of a diet program should be instilling discipline and self control. One can still join their friends when they dine out but they should learn to choose the right food and ask for the right servings.

You are what you eat. If you eat too much fat, then you’ll probably end up fat. Always remember to eat foods like fruits, vegetables, low-GI foods, and foods with low fat contents. If you have been accustomed to eating fatty and salty meals and junk foods, then your body might tell you that fruits and vegetables don’t taste that good. You then have to retrain your taste buds and body by eating as many fruits and vegetables as possible. If you keep eating them, you’ll start to enjoy them later on.

Teen weight loss: Taking it slowly is still the best

According to recent studies more kids nowadays are mild to severely overweight. The 1999-2000 National health survey indicates that 15 % of children and teens are overweight.

The figure is nearly double that what was recorded a decade or so ago. Some blame their present lifestyle while others blame the lack of discipline in teens nowadays. Regardless of the reasons, teen weight problems are real.

But unlike weight loss programs for adults, teen weight loss programs are a little tricky since such programs when left uncheck can be potentially dangerous for their health. Because of the potential danger, dietitian and nutrition experts approach the subject with caution.

The basic problem with teen weight loss is that their bodies are still growing and developing and cutting down food intake will greatly influence their growth. It is therefore important that diet programs for teens should cover all their nutritional needs.

For teenagers, they generally need to grasp some basic concepts about eating right. If they eat too little, their health will be put at risk. But similarly, if they eat more that they should, the extra food turns into body fat causing weight issues. Teenagers should learn to eat food less with saturated fats.

These foods include those fried in fat and oil like fried chicken, burgers, potato chips, french fries, potato chips and other fatty meat. Meanwhile, they also should avoid foods that are high in fat and sugar contents like cakes, chocolates, butter, cream, peanut butter, pies, cookies, and generally any sweets and sweet based desserts.

A lot of diet programs claim to be the best solutions for over weight teens. These claims generally revolve around two basic concepts: the right diet and regular exercise. In reality, the quickest and easiest way for teens to loose weight is still the having the right diet and right exercise. Teens should always avoid diet pills.

Most of the kids or teens today eat fast foods, get exceedingly large food portions and are really extremely lazy lacking the necessary activities to build a healthy body. Simple outdoor activities for teens can help them loose some of their excess body weight. When you cut grass use a push mower, for example. Engage in activities like playing Frisbee which would help you exercise without even realizing it.

There’s really no quick way to loose weight. You need to work the excess fat off your body. It is the right combination of diet and exercise which will help you loose weight. But the problem with dieting and exercising is keeping motivated and goal oriented. Kids find dieting intimidating and regular exercise boring.

This is why full family support is necessary if you want your kids to loose some weight. You need to keep your kids and teens motivated. Encourage them and help them overcome their cravings by cooking, serving and eating the same food diets that they eat. Get them to be more active. If they find regular exercises boring, join them in other activities such as sports.

Teach them what to look for when they eat outdoors. Tell them the benefits of foods and teach them how to read food labels. You may be able to control their diet while they stay home but when they go outside and eat with friends, then you might have a problem. It is therefore important in any diet to implant a sense of self discipline and pride in what they do.

Is it true? Are there really easy ways to lose weight fast? Well, I guess that really depends on two main things: how much weight do you need to lose and what do you consider “fast”?

If you only need to lost a few pounds, say 2 up to 10, than you can probably drop that weight pretty quickly and easily. If, on the other hand, you need to lose 15 or more pounds and you want to do it in a week or two, you may not have realistic expectations.

There are some easy ways to lose weight fast, but most of them will only involve losing some water weight and will only result in losing a few pounds. The water weight will usually come right back as soon as you starting eating normally again.

The fast methods don’t usually include actually losing excess body fat. Losing the excess body fat, as opposed to only losing water weight, is the only real way to lose weight and have it stay off (at least as long as you don’t just go back to your old habits of eating).

Many of these fast weight loss plans will revolve around some sort of liquid fasting or cleansing. There are many variations but the general theory is the same:

1. You will greatly reduce, or eliminate completely, eating solid foods for several days.

2. During that time you will ingest only liquid shakes or some sort of cleanse mixture. There are many recipes online that you can try. The idea is to provide your body with the nutrients it needs and/ or help you flush toxins out of your body.

For the most part, these types of weight loss plans are good for getting off to a quick start but if you need to lose more than 10 – 15 pounds, it’s unlikely that you will get the results you want from just this method.

I don’t mean to be the bearer of bad news but any significant weight loss is going to take some time and it is going to be the result of a combination of watching what you eat as well as some sort of physical activity.

Pills, potions and gadgets will only get you so far, from that point on you will need to get more exercise and eat less (also eat better).

But, having said that, don’t make the mistake of thinking that to lose weight you need to go hardcore. Some simple lifestyle changes can make a big difference. The most important thing to remember is that unless you want to gain the weight back right away, you have to make permanent lifestyle changes.

Just going on a “diet” will only allow you to lose weight, but if you don’t make permanent changes you will just gain it all back sooner or later.

There may not really be such a thing as easy ways to lose weight fast if you have a lot of weight to lose. But there are some simple things you can do to make changes to your life that will result (maybe not in quick) but permanent weight loss.
