Lose Weight While Catching Tan - the Benefits of Sun Exposure
Sun exposure may lead to weight loss because the ultraviolets stimulate the secretion of a hormone of the pineal gland. This hormone burns the fats under the skin. The hormone`s effect is benefic if dieters follow a certain “beach” program during the summer, according to recent studies.

The efficiency of this program also depends on the diet that dieters follow, and the hours of sleep. The ultraviolets should be avoided in the first seventy or eighty minutes after sunrise. The ultraviolets during this period may have unwanted effects, such as gaining weight, for sixty-five percent of the women and seventy percent of the men. Dieters should not consume sweet beverages during the first three hours after sunrise.

These beverages contain artificial sweeteners that may lower the level of certain hormones. Dieters should avoid mineral water when they are at the beach and do not expose to the sun for more than an hour per day. It is not recommended to go to the beach between 11:30a.m and 3:30p.m.

Always consume water each time you feel thirsty and you`re at the beach and sleep between thirty minutes and an hour and half after beach. Do not consume sweet, distilled beverages within one hour before going to sleep.

Easy workout or sports are required before each session of sun exposure. In the evening, it`s good to go to the beach at around 6.00 p.m. and until sunset, and try to fall asleep on a comfortable support. The soft, comfortable sensations stimulates certain substances that enhance the ultraviolet`s effect.

Count Your Chances – Obesity Calculator
It is necessary to know how overweight and obesity are defined and measured. An introduction to these things helps us understand and find our place in the chances for obesity. Calculating your chances for obesity may take a lot of patience. It is good though that our helpful health providers have devised a way for patients to determine their weight condition easily. An obesity calculator makes the process of weight measurement comprehensible and convenient to use.
The obesity calculator doesn’t actually need a special calculating device in order to use. There is a lot of free obesity calculator software in the internet, available usually in health and wellness web sites. Just a few clicks and you got your BMI. But did you know that you can compute for your BMI on your own?

The body mass index or the BMI obesity calculator is a special formula designed to measure the amount of body fat in a person’s body. Since not all overweight people are fat people (for example body-builders), being informed of your exact BMI and the related changes in your body allows you to know as early if you are obese. And if you’re not, wouldn’t it feel good to know you’re not obese even it seems you are? Even thin people also get the advantage of knowing the balance between their lean muscles and fats. The method is fairly easy.

The BMI calculates based on the standard relationship between height and weight. Though it doesn’t measure the exact percentage of fat in your body, it does measure the (right) proportion of your fat and muscles. And since it is not gender-specific and effective as well as easy to use, it is the choice-measurement used by most obesity researchers and other health professionals.

Though, you don’t need to be an expert at all. You’re already on your way to having your obesity calculator once you know your math. The BMI is computed by dividing a person’s weight (in kilograms) by his height (in meters) squared. In figures: weight (kg) / height squared (m²). If you want to use pounds and inches, just multiply your weight (lbs.) by 700, then divide the result by your height (in.), and then divide that again by your height in inches. A BMI that is less than 18.5 is considered underweight. A BMI of 18.5-24.9 is considered normal-weight. A BMI of 25- 29.9 is considered overweight.

In essence, you will be able to have a personal conviction with your weight- health once you become knowledgeable of what goes on with of your BMI as you follow through with its development. – It’s having a personal obesity calculator onwards to giving you either relief, or attention. ***

Why You Should Use A Body Mass Index BMI Calculator
Body mass index is defined as the individuals body weight divided by their height in inches. It is a measure of obesity (or non-obesity). BMI is not a diagnostic tool, it is an indicator of weight status. It is a better indicator of excess body fat than body weight measurement alone, which is why medical professionals rely on the universal body mass index scale when evaluating patients health.

The Body Mass Index is generally used as a means of correlation between groups related by general mass and can serve as a vague means of estimating adiposity. This is just one of many factors related to developing a chronic disease (such as heart disease, cancer, or diabetes). As a measure, it became popular during the early 1950s and 60s as obesity started to become a discernible issue in prosperous Western society.

Obesity has become increasingly prevalent in the United States and in Europe over the past several decades. Obesity has been linked to the increased risk of cancer, heart disease, and other health problems. About 14% of cancer related deaths are due to obesity in men over 50 years of age. BMI for adults fall into one of these categories, normal, overweight, obese, or underweight. The only disadvantage of using the Body Mass Index is the difficulty in interpreting the units to actual weight (in pounds) that must be lost.

A BMI nearing 15 is usually used as an indicator for starvation and the health risks involved such as anorexia nervosa. Obesity is defined as a BMI of 30 or if their weight is 20% greater the average person in their age and gender. Extreme obesity is a BMI of 40 or more which is found in 2% of men and 4% of women in the US.

In the United States, it is also used as a measure of being underweight from suffering with eating disorders such as anorexia nervosa and bulimia nervosa. However, BMI categories do not take into account many factors such as frame size and muscularity.

In fact, some argue that the error in the BMI is significant and so pervasive that it is not generally useful in evaluation of health. For instance, professional football players who bulk up could be considered obese but are in very good shape and the scale might not reflect their overall health.

If your body mass index is 30 or higher it is recommended that you seek help with progressive weight loss through diet combined with regular exercise such as walking daily.

While the technique for calculating body mass index is the same as in adults, the results are measured differently in children because they are still growing. ***

How To Determine Your Ideal Body Weight
Use the body mass index (BMI) to calculate your ideal healthy body weight. The BMI calculator is a method used to determine whether you are currently underweight, overweight or obese. This test works for all age groups, genders and body types.

Here's how it works. Take your weight in pounds and divide by your height in inches squared.
Weight in pounds / (Height in inches) x (Height in inches)
Multiply this figure by 703 to calculate BMI

Here's the scale to measure your results:
-BMI below 20 is considered underweight
-BMI between 25 and 30 is considered overweight
-BMI over 30 is considered obese

Example
Let's take a 220 pound male who's 6 feet 2 inches tall and calculate his BMI.
6 feet two inches = 72 inches
72 x 72 =5184
220/5184 = 0.0424
0.0424 x 703 = 29

By looking at the BMI scale, we can see that the subject of our example is overweight.

The BMI calculator is just a way for you to confirm, through objective means, that you need to lose some pounds. How many pounds should you shed? That's entirely up to you. You know your tendencies and you know what makes you feel comfortable. Use the BMI index to get a general idea of where you need to go. Set up an ideal scenario where you lose a certain amount of pounds. Be reasonable with your weight loss plans. Set goals that you know you can achieve.

Analyze your eating habits. Identify your strengths and weaknesses. Enable good behavior and try to limit unhealthy tendencies. If you eat lots of fruits and veggies or cook complete meals, these are things that you can build on. If you overeat, miss meals or snack too much, then these are habits that'll require adjustment. Discover the reasoning behind your personal eating habits. Do you overeat when you get emotional, bored, lonely or stressed? When you find out what's driving your behavior, you'll be better prepared to adjust your habits.

Think about past diets or weight loss plans that you have experienced. What was successful about your previous efforts? What aspects of your previous weight loss attempts were unsuccessful? If you need a diet solution that'll allow you to be flexible, consider the UnDiet weight control system. UnDiet is a system of supplements designed to improve your metabolic rate and control bouts of hunger. UnDiet is an effective, convenient and unrestrictive way to jumpstart a long-term weight loss strategy.

Once you've identified your strengths, weaknesses and ideal body weight, you can then begin to craft a strategy for long-term weight loss. This strategy will be based on healthy eating and exercise. Just make sure that you can find the right balance between calorie intake and calorie burning. ***

Weight Loss Using BMI And BMR
Weight Loss seems almost impossibly complicated for us normal people. We struggle with this program and that, never understanding what's going on and being made to feel guilty if we don't look like a TV celebrity. It's really quite simple...we gain when we take in more calories than we use up...we lose when we take in less. The trick is in knowing how much we should weigh, the number of calories we need and how to balance our diet to get those calories in a healthy way. Fortunately, BMI and BMR can help us know what we need to get to the right weight.

BMI-Body Mass Index: The BMI can give us an approximation of what we should weigh, based, primarily on our height. All you need to do is plug your height and weight into an online Calculator (see BMI Calculator link below) to find out if you're underweight, normal, overweight or obese. Then work the weight numbers backwards to find out what "normal" is for your height. Now, I strongly believe the person who invented this was anorexic, so, don't be surprised at how light "normal" is. I said it was an approximation! There are wide variations in healthy weight among humans of the same height, like sex and frame size. Another common variation is, as we get older, we can afford to be a little more, shall we say, fluffy. The point is, you now have a way to figure out how much you should weigh based on something more objective than the TV.

BMR-Basal Metabolic Rate: Your BMR is basically, the number of calories your body needs to maintain its current weight. Like the BMI, it's an approximation. If you're an athlete, for instance, you'll need many more calories...couch potatoes need less, but then, couch potatoes don't read this far into a health article. To get your BMR, simply enter your sex, age and weight into a Calculator (see BMR Calorie Burning Calculator below). The number you get out is the number of calories you need to maintain your current weight.

Using The BMI And BMR For Weight Loss: Now, here's where BMI and BMR can be powerful weight loss tools. The BMI Calculator page instructs you how to adjust the BMI for the two most common variations...sex and frame size. Once you've taken the BMI normal weight and adjusted it for sex and frame size, you have your "goal" weight. Instead of your current weight, enter this "goal" along with your sex and age into the BMR Calorie Burning Calculator. The new number of calories are the daily amount you need to slowly lose weight down to your goal and maintain it (optimum calories). Of course, check all of this with your doctor before making any changes because certain medical conditions require special consideration. Still, with BMR and BMI, it's pretty easy to know where the goal line is...the final step is how to get to the goal line.

Fat, Protein, Carbs, Fiber, Water: Once you know your optimum calories, it's simply a matter of balancing your daily food intake to add up to that total. There are so many different ideas of how to do that, I'm only going to glance over it in this article. In the near future I'll be publishing articles to cover different dietary balance styles for different circumstances. The new USDA Food Pyramid can give you good ideas on balancing your fats, proteins, carbs, fiber and water. If you make sure to keep your diet balanced and keep the daily calories near your optimum, you should slowly and comfortably lose weight until you reach your goal. As an added plus, once you get to the goal, you don't have to change a thing...you've been doing the right thing all along. ***

BMI Calculator for Adults
Now for many of you fitness enthusiasts out there including myself, you will notice that your BMI actually falls into what is considered the obese range. I first stumbled upon this a few years back when BMI was getting a lot of press and thought to myself this really isn’t accurate. What if you have a high amount of lean body mass?
For someone carrying more muscle mass than the “average” adult they will judged as obese through this ranking system. Even worse, what if my health insurance gives me higher premiums or I’m designated as a higher risk for obesity related ailments such as heart disease, diabetes, etc?

This was obviously very disheartening but fortunately a recent study published in the International Journal of Obesity has shed some light on this conundrum. They clearly state that the BMI rankings has severe limitations in both sexes and doesn’t accurately describe the relative obesity in severely obese subjects either.
Thankfully, a well respected journal has gone against the grain of popular medical opinion to bring these truths to light. If you feel you or your children have been diagnosed with a high BMI without just cause please present the following citation to them. After all, life is a never ending learning process and those of living the fitness lifestyle certainly are not AVERAGE.

The Body Mass Index Isn’t As Accurate As You Think!

As you delve into the world of muscle building and fitness you often come across stark contrasts with current medical opinion. Those who tend to push the envelope on the competitive side as they ascend through to the professional ranks often look great, but epitomize what it means to be unhealthy. It’s just the way it is. However, most of us exist somewhere in the mediocrity and do indeed live a healthy and fit lifestyle.

One tool the medical world has used to assess obesity is the Body Mass Index, or more commonly referred to as BMI. According to the Center for Disease Control & Prevention BMI is defined as “a number calculated from a person’s weight and height. BMI is a reliable indicator of body fatness for people.

BMI does not measure body fat directly, but research has shown that BMI correlates to direct measures of body fat, such as underwater weighing and dual energy x-ray absorptiometry (DXA).1, 2 BMI can be considered an alternative for direct measures of body fat. Additionally, BMI is an inexpensive and easy-to-perform method of screening for weight categories that may lead to health problems.”

1Division of Cardiovascular Diseases, Mayo Clinic College of Medicine, MN, USA.
Body mass index (BMI) is the most widely used measure to diagnose obesity. However, the accuracy of BMI in detecting excess body adiposity in the adult general population is largely unknown.Methods: A cross-sectional design of 13 601 subjects (age 20-79.9 years; 49% men) from the Third National Health and Nutrition Examination Survey.

Bioelectrical impedance analysis was used to estimate body fat percent (BF%). We assessed the diagnostic performance of BMI using the World Health Organization reference standard for obesity of BF%>25% in men and>35% in women. We tested the correlation between BMI and both BF% and lean mass by sex and age groups adjusted for race.Results: BMI-defined obesity (>/=30 kg m(-2)) was present in 19.1% of men and 24.7% of women, while BF%-defined obesity was present in 43.9% of men and 52.3% of women. A BMI>/=30 had a high specificity (men=95%, 95% confidence interval (CI), 94-96 and women=99%, 95% CI, 98-100), but a poor sensitivity (men=36%, 95% CI, 35-37 and women=49%, 95% CI, 48-50) to detect BF%-defined obesity.

The diagnostic performance of BMI diminished as age increased. In men, BMI had a better correlation with lean mass than with BF%, while in women BMI correlated better with BF% than with lean mass. However, in the intermediate range of BMI (25-29.9 kg m(-2)), BMI failed to discriminate between BF% and lean mass in both sexes.Conclusions: The accuracy of BMI in diagnosing obesity is limited, particularly for individuals in the intermediate BMI ranges, in men and in the elderly. A BMI cutoff of>/=30 kg m(-2) has good specificity but misses more than half of people with excess fat. These results may help to explain the unexpected better survival in overweight/mild obese patients. ***

Obesity Increases the Prostate Cancer Death Risk

Obese men suffering from prostate cancer are two-and-a-half times more likely to die from it compared to normal-weight men, according to a recent study from Fred Hutchinson Cancer Research Center.
The study involved almost eight hundred middle-aged men who were recently diagnosed with prostate-cancer, and followed the subjects for ten years. Seventeen percent of the subjects were obese and six percent of them died of prostate-cancer.

The mortality risk from prostate cancer for obese men is not related to the treatment, or prostate cancer stage at the time of the study, said Dr. Alan Kristal, senior author of the study. The risk for obese men is of 2.6 times greater compared to healthy weight men, regardless of the cancer diagnostic profile.

The results of the study are not related to whether the patient is subjected to radiation treatment, radical prostatectomy, or androgen-deprivation therapy. It does not matter if the subject suffers from a high grade cancer, or low-grade, localized, distant, or regional cancer, says Kristal.

Particularly, men with regional or local prostate-cancer have a 3.6-time higher risk of metastasis, or cancer spreading to other organs, than patients with a healthy weight. Obesity was strongly connected with prostate cancer especially for men with regional disease, meaning cancer that has already started to spread to surrounding tissues, compared to those with early cancer.

Researchers believe that inflammation and steroid hormones are behind the connection between prostate-cancer and obesity. Obesity is considered a massive inflammatory condition, which modifies the levels of serum estrogens and increases factors that lead to cancer growth, according to Kristal.

The study`s results are the first strong evidence showing that losing weight can be benefic for men with prostate cancer, by reducing the risk of death from the disease, said the researchers. ***
