Obesity treatment could help kick start people's healthy eating plans as a fast food chain has plans to display nutritional information for its products.
McDonald's has recently announced that it is to display calorie information for all of its food on menu boards in its UK outlets from September this year.
Tam Fry, spokesperson for the National Obesity Forum, said that it would be "wonderful" if the plan helped people eat healthily.
However, he added that it is unsurprising that McDonald's own research found that just one in five people would think more about what they were eating if the calorie content was displayed.
"It takes a long time for people to change their attitudes and change their behaviour," he noted.
"Therefore I would not expect an immediate response to this, but over the course of time I really do believe that people are starting to become more conscious of the food that they eat, and of the amount and calories that they eat."
