A group of British cardiologists want to clear a few things up for us. An editorial
published in the British Journal of Sports Medicine,
says that you can't outrun a bad diet and although regular exercise is good for reducing the risk of heart disease, dementia, some cancers and type 2 diabetes, it does not promote weight loss
on its own. It must be paired with dietary changes.
The authors of the study say that the public is "drowned by an unhelpful message" from the food industry that obesity is caused by lack of exercise. They compare it to the tobacco industry after the cancer links came to light. "The tobacco industry successfully stalled government intervention for 50 years," they say. "This sabotage was achieved using a ‘corporate playbook’ of denial, doubt, confusing the public and even buying the loyalty of bent scientists, at the cost of millions of lives."
The authors note that the industry has also shifted the focus towards basic calorie counting when it is the source of those calories that is important. Calories from sugar store as fat while those that come from fat make you feel full.
The authors point to a study
in the academic journal Nutrition
that says the single most effective way to counter obesity is to restrict the intake of carbohydrates.
The editorial is scathingly critical of sugary drinks, saying that the association between "junk food and sport, must end." It goes so far as to ask the British government to put a tax on sugar drinks, ban advertising of junk food and gyms shouldn't sell the beverages.
Britain's Food and Drink Federation emailed a statement to Mashable
rejecting comparisons to the tobacco industry. "Britain’s food and drink manufacturers are proud of their long track record of working to help improve UK diets and promote healthier lifestyles. But they’re not complacent, recognising the scale of the obesity challenge in the UK," the statement says, pointing to the introduction nutrition information on food packaging and a push towards a reduction of salt usage. Yes, companies are taking action to highlight the importance of physical activity. However, they recognise that where they can have the biggest impact is in helping people to achieve a balanced diet," they say.
