86 percent of Americans may be overweight by 2030.
The World Health Organization (WHO) has set BMI limits or body mass index (KMI).
KMI is an expression of weight relative to height, and is equal to the weight divided by the square of height.
For example, a person of 1.60m and 55kg will get the KMI on:
55: (1.6 x 1.6) = 55: 2.56 = 21.5 kg / m2.
A person of 1.80 meters, according to the WHO limits, has a normal weight in the range of 60 to 81 kg, precursor to obesity in the range of 81-97 kg and obesity by weight over 97 kg.
Similarly, a person with a height of 1.65 m will have normal weight in the range of 50 to 68 kg, precursor to obesity in the area of 68-82 kg and obesity if the weight is over 82 kg.

BMI and Health
KMI under 18.5
Disease risk: Low for diabetes, increased for other health problems
Disease Risk: Low
KMI over 24.9
Disease Risk: Increased for Diabetes
Disease risk: Increased for diabetes, increased mortality
Disease Risk: High Risk of Multiple Health Issues, Increased Mortality
Very severe obesity:
KMI over 39.9
Disease risk: Further increased health risk

If today’s development continues at the same rate, as many as 86 percent of all adults Americans will be overweight or obese by 2030, research.no writes.
This will mean public health crisis in the US with huge costs, a new study shows.
The costs of the obesity affect the US economy, estimated at nearly $ 957 billion, or around $ 5 billion.
– This will mean that one of six healthcare officers will cover overweight and obesity-related costs, “says the study’s principal author, Youfa Wang.
Obesity extinguishes the budget
Today, 65 percent of all Americans are overweight or fat.
– We expect that the costs associated with obesity and overweight will more than double every decade, says May A. Beydoun, one of the co-authors of the study, which supposedly is an underestimation of costs.
The calculations in the study show that obesity alone will extinguish as much as 15-17 percent of health careers.
– Dramatic Measures Required
The authors of the study call this a public health crisis, and that dramatic and effective measures are the only ones that can help.
They also believe that the US Department of Health will not reach its goal of reducing the proportion of obese by 2010 if the current trend continues.
Obesity epidemic also in Norway
The research was conducted at Johns Hopkins Bloomberg School of Public Health, the Agency for Healthcare Research and Quality, and the University of Pennsylvania School of Medicine.
The Norwegian Institute of Public Health writes on its web pages that there are no good numbers for all of Norway, but results from regional surveys reinforce the suspicion that Norway is also developing an obesity epidemic.
Among the 40s and 45s, men weigh 5kg more and females 5.8kg more than 15 years ago.
Still more developing obesity, in some counties now one in five 40-45 year olds are overweight or obese.
New survey on-going
– We have several local studies of weight in adults, adolescents and children, but we need a comprehensive overview for the whole of Norway. In the case of children, the Norwegian Institute of Public Health will be part of a WHO study that will give us Norwegian figures for an entire age group, “says Bjørn Heine Strand of the Norwegian Institute of Public Health.
Overweight and fat are at higher risk for a variety of diseases, such as high blood pressure, type 2 diabetes, heart disease and stroke.
