Carbs and sugar behind obesity rise
Excess sugar and carbohydrates - not physical inactivity - are behind the surge in obesity, health experts have claimed. Writing in the British Journal of Sports Medicine, they said poor diet now generates more disease than physical inactivity, alcohol and smoking combined.
They said that while obesity has rocketed in the past 30 years, there has been little change in physical activity.
"This places the blame for our expanding waistlines on the type and amount of calories consumed," they wrote.
The "false perception" that exercise matters more than healthy eating is due to how the food industry is marketed, they argued, describing it as "chillingly similar" to the tobacco industry.
