Britons must ensure they take responsibility for monitoring their own eating habits and weight, but the government can do more to increase public awareness, it has been claimed.
According to British Hospitality Association spokesman Miles Quest, it is too early to determine whether a recent initiative to print calorie counts on restaurant menus has had the desired impact, but some consumers have displayed a lack of interest.
"When people eat out, as an eating out experience, they don't want to know too much about the calorie count," he explained. "It is very difficult to know how people will interpret the calorie counts."
Mr Quest also pointed out that it is not just food that contributes to Britain's current obesity problem, with many drinks also high in fat and many people receiving an insufficient amount of exercise to avoid piling on the pounds.
A report published in the British Medical Journal earlier this week suggested customers at fast food outlets in the US had tended to buy lower-calorie products since the introduction of a labelling system.
