It has been suggested that the current 'obesity epidemic' has been caused purely due to the fact that people are eating too much.
Professor John Speakman made the claim in the national press, noting that modern sedentary lifestyles have very little to do with the issue.
To illustrate his views, the professor claimed that overall physical activity levels have remained constant over the last 25 years, while weight levels have shot up.
Professor Jonathan Pinknet, expert in the field on obesity at the Peninsula College of Medicine and Dentistry, Plymouth, commented further: "In a world where the average has changed, people may continue to think that they are the average when they have actually become quite overweight."
He added that the "30 per cent systematic underestimation of calorie intake" is affecting people's weight.
The latest statistics show that in 2008 almost a quarter of adults (24 per cent of men and 25 per cent of women) in England were classified as obese.
