Exercise Can't Save Us: Our Sugar Intake Is The Real Culprit, Say Experts
Quote:
In a fascinating and scorching editorial in the British Journal of Sports Medicine, three authors argue that the myth that exercise is the key to weight loss and to health is erroneous and pervasive, and that it must end. The evidence that diet matters more than exercise is now overwhelming, they write, and has got to be heeded: We can exercise to the moon and back but still be fat for all the sugar and carbs we consume. And perhaps even more jarring is that we can be a normal weight and exercise, and still be unhealthy if we're eating poorly. So, they say, we need a basic reboot of our understanding of health, which has to involve the food industry's powerful PR "machinery," since that was part of the problem to begin with.
The major point the team makes which they say the public doesn't really understand is that exercise in and of itself doesn't really lead to weight loss. It may lead to a number of excellent health effects, but weight loss if you're not also restricting calories isn't one of them. "Regular physical activity reduces the risk of developing cardiovascular disease, type 2 diabetes, dementia and some cancers by at least 30%," they write. "However, physical activity does not promote weight loss."
