Calories in vs. calories out?
Weight management is not as simple as the ‘calories in, calories out’ model of energy balance, according to researchers.
Indeed, speaking at this year’s International Conference of Nutrition (ICN) in Granada, Spain, Professor John Blundell of Leeds University noted that while the model that is particularly beloved by food and beverage companies – especially those selling high-calorie products – the idea that weight management is a simple balance between the calories taken in through food and drink and those expended through physical activity increasingly is being called into question.
"This idea is completely false,” he said.
