It’s no secret that experts recommend putting away blue-light devices, such as smartphones, tablets, and laptops, at least an hour before bed to improve sleep quality. However, a recent pilot study from Northwestern University shows that exposure to blue-light at night can impact glucose metabolism. Although the exact correlation is still being studied, John La Puma, MD, suggests ceasing exposure to blue light two hours prior to hitting the sack. “It resets melatonin levels so that getting to sleep becomes harder, and too little sleep means weight gain for most people,” says Dr. La Puma.
When it comes to weight loss, a strong metabolism is the key to not only reaching your goals, but also to reaching them in record time. Sadly, many diets and weight loss programs have the opposite effect and wind up lowering your body’s ability to burn calories, making your journey to your ideal weight much harder than it has to be. So, if you struggle with losing weight or don’t feel like the numbers are reducing as quickly as you’d like, here are nine effective actions you can take that will put your metabolism (and your weight loss) in higher gear:
Plus, strength workouts have an additional metabolism-boosting benefit. Because this type of anaerobic training involves breaking down and building back up of muscle tissue, the body needs to burn more calories in the 24 to 48 hours after each session—a phenomenon known as excess post-exercise oxygen consumption, EPOC, or, informally, "afterburn.” Researchers, however, are currently debating how intense that afterburn really is.
