Dieting, not exercise, key to losing weight

Published on 16/09/2010
Those looking to lose weight as part of their healthcare plan have been advised they need to focus on their diet more than exercise.

Speaking to the British Science Festival this week (September 15th), Professor John Speakman of Aberdeen University said that the current obesity epidemic is down to people eating more, rather than exercising less.

Prof Speakman, director of Aberdeen's Institute of Biological and Environmental Sciences, presented research that shows that levels of activity in the general population have not fallen since the 1980s.

His team reviewed studies from this period that looked into energy expenditure and claim they show that overall physical activity rates have remained steady over the years.

He said that an obese person with a body mass index (BMI) of 35 would have to exercise four to five hours a day to reach a healthier BMI of 22.

However, they can achieve the same result by reducing their calorie intake by one third.

"It is important for policy makers to realise that, if they want to promote weight loss in overweight and obese people, the most effective way to realise this is through promotion of healthy eating practices, not through exercise regimes," he said.

One in five people in Britain are clinically obese.

Proactive, efficient, and offered me insurance I need. I would say half price I would end up paying if I did it by myself. Many thanks.

Excellent service. Explained everything in detail and really helped to find the right insurance best suited to my needs - which wasn't necessarily the most expensive.
