Study: exercise doesn’t help weight-loss

I myself have long concluded that while exercise is good for health, it’s a very small component of weight-loss. Anyway, here’s the article.

LONDON — A team of British cardiologists have said it’s time to “bust the myth” that regular exercise tackles obesity.

The strongly-worded editorial in the British Journal of Sports Medicine, published in the May edition of the journal, says you can’t outrun a bad diet and that although regular exercise reduces the risk of developing a number of health issues such as heart disease, dementia, some cancers and type 2 diabetes, it doesn’t promote weight loss.

The authors of the study say the public is “drowned by an unhelpful message” from the food industry that obesity is caused entirely by a lack of exercise, going so far as to describe the tactics used as “chillingly similar” to those employed by big tobacco companies when the links between smoking and lung cancer were first revealed.

“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 food industry has also shifted the conversation to simple calorie counting, the authors write. But it’s the source of calories that matters, the editorial says, arguing that sugar calories promote the storage of fat and make people more hungry, while calories that actually come from fat make a person 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.
