Lack of Sleep Linked to Weight Gain
You eat healthy and exercise regularly but still have difficulty managing your weight. The problem may be lack of sleep.
A new commentary in the Canadian Medical Journal finds that fatigue influences the levels of certain hormones involved in regulating hunger. Specifically, people who do not get enough sleep tend to eat more at night. Eating late at night can sabotage any weight loss plan.
Lead author of the study Jean-Phillippe Chaput told the Canadian Press, "If people want to lose weight, of course at some point they will need to cut calories. But if they don't take into account their sleeping patterns, they might fail. They have more chances to fail over the long term."
The Mayo Clinic earlier this year echoed this advice. The Mayo researchers monitored 17 adults in a controlled lab environment for more than a week. Participants consumed 549 more calories if their sleep was reduced to two-thirds their normal amount. Even if they were awake longer, they did not burn much more calories.
Getting adequate sleep does more than help manage your weight. Sleep helps improve concentration, boost your immune function and keeps you alert. Inadequate sleep raises the risk of high blood pressure, heart disease, and now science has found, weight gain.
