A new global analysis reveals that Canadian women are getting obese much faster than any other women in the high income world. This daunting trend took off after 1980 and obesity rates have almost doubled up.

Experts believe that the changes in our lifestyles and food choices are responsible for this daunting trend. They blame ready to eat food, takeaways and lack of physical excursion for this.

Researchers try to explain this transformation with the help of body mass index concept which is a fat measurement technique based on height and weight. According to the World Health Organization, if the BMI is more than 25, then the person is to be considered overweight.

The average BMI for Canadian women was around 24.1 in 1980 but it rose to 26.7 in 2008 and for men it went to 27.5 from 25.2.

Doctors opine that only advice and exercise are not resolving this problem and Dr. Arya Sharma, scientific director of the Canadian Obesity Network and a professor of medicine at the University of Alberta, believes that this problem has become so deep-rooted that it will take decades to reverse its effects.

"We need to get serious about thinking about treatment. We can all hope that prevention is eventually going to work, but it's not going to work anytime soon and it certainly does not look like it's working right now, because the numbers are continuing to rise," Sharma says.
