It’s great to see articles like this that reinforce how a healthy body/mind automatically balances calories in and calories out…and how food quality is key to keeping the brain balancing us out automatically.
“Responsibility for monitoring calorie input and energy output falls to the brain. And the job is not easy, says endocrinologist Michael Schwartz, director of the University of Washington’s Diabetes and Obesity Center of Excellence in Seattle.
To maintain a constant weight, a 160-pound man would need to consume “about 1 million calories over the course of a year,” Schwartz explains — “and expend almost exactly that same million calories.” Only by integrating hosts of chemical signals day and night can the brain manage this energy-budgeting feat, which it has done quite well for most people throughout most of history.
Together, these findings suggest that the brain, a longtime master at tracking caloric intake, can be fooled. And when that happens, Swithers observes, weight management suddenly becomes challenging. “Now we have to start counting calories, reading food labels and tracking how many steps we took today,” she says.”
