Theoretical facts is that individual who are overweight or obese run a greater risk of developing diabetes mellitus, hypertension, coronary heart disease, stroke, arthritis, and some forms of cancer. The body mass index (BMI) is commonly used to determine desirable body weights.

BMI is a measurement of an adult’s weight in relation to height, and it is calculated metrically as weight divided by height square (kg/m2). People with BMI of 25.0 to 29.9 are considered overweight and people with BMI of 30 or above are considered obese. Do compute your BMI.

Body mass index only provides a rough estimate of desirable weight, however. Weight alone may not be indicator of fat, as in the case of a bodybuilder who may have a high BMI because of a high percentage of muscle tissue, which weighs more than fat. Likewise, a person with a sedentary lifestyle may be within a desirable weight range but have excess fat tissue. In general, the higher the BMI, the greater the risk for developing serious medical conditions.
Studies have shown that meal replacements are often more effective than very low calories diets, resulting in an increase in the amount of initial weight loss and enabling dieters to maintain their weight loss. Regarding diet pills, it would only take over a sex month period that weight loss medication may result in a 10-percent body weight reduction. Weight loss slows or stops after six months, and discontinuing medication usually causes weight regain. However, the continued use of diet medications keeps most of the lost weight from returning for two years.

Caloric restriction alone will not produce long-term weight loss. Research clearly indicates that regular exercise is the single best predictor for achieving long term weight control. Regular exercise will also improve some of the medical conditions associated with obesity, including elevated blood cholesterol, hypertension, and diabetes mellitus. Prevention is better than cure and obesity is preventive.

This is a little bizarre: while cases of mouth cancers caused by tobacco and alcohol have being decreasing since 1982, due to their lower consume, a new culprit for this type of cancer is causing increasingly more victims: oral sex.

More specifically, a human papilloma virus (HPV), which can be
transmitted through oral sex, causes tongue, mouth and throat cancers, besides cervical, penile and anal cancers. The number of this type of cancers has risen by 33% from 1973 to 2004, as found by a team led by Maura Gillison at Johns Hopkins University in Baltimore, Maryland, US, in a research published in the “Journal of Clinical Oncology.” The researchers used data recorded in the US National Cancer Institute registries, recording about 46,000 cases.

“What we do know is that the prevalence of HPV is high, particularly among young people and this shouldn’t be a surprise given that, since the sexual revolution, people have been having more sexual partners,” Lesley Walker, director of cancer information at Cancer Research UK, told NewScientist.

“The rise was largest among young white males, suggesting this group is more likely to have oral sex at a younger age now than it was 20 years ago. It adds that further research on the role of race and sex, and oral sexual behavior, is needed,” wrote the authors.

“What is not in doubt is the need to consider giving boys the HPV vaccine, to protect them from the disease,” said Gillison.
There is already a Merck vaccine targeting HPV strains responsible for cervical (uterus) cancer in young women and girls. The same viral types are also known to provoke oral, penile and anal cancers. The HPV16 strain is particularly aggressive.
“We need to start having a discussion about those cancers other than cervical cancer that may be affected in a positive way by the vaccine,” said Gillison.
