Mar 03, 2014 6 Ways You are Hurting Your Metabolism You may have inherited your parents slow metabolism, but you’re not stuck with it. Take control of your metabolism by reading about what you might be doing to slow it down. Cutting out caffeine: Sometimes caffeine gets a bad rap but it can actually give your calorie burn a slight boost. This doesn't mean that you should start knocking back the stuff like water but if you’re already drinking green tea or coffee most days, keeping it a part of your routine could help your metabolism run at top speed. Skimping on Sleep: People who are sleep-deprived on a regular basis tend to weigh more than those who get a good night’s rest most nights. Why? Research shows it can throw the hormones that control appetite out of whack, making you hungrier and causing you to eat more. Striving to get a good seven hours, no matter how hard it may be, will do wonders for your health and metabolism. Eating Pesticides and Eating Off of Plastic: If you've tried everything and are still seeing no progress, maybe it might be time to look at where your food is coming from and what’s being sprayed on it. Some of the chemicals in plastics and pesticides are endocrine disruptors called obesogens, which can set you up for weight gain. Neglecting Vitamin D: When you’re low in vitamin D, you lose weight slower and your levels of ghrelin, a hormone which makes you hungry, are higher. It can be difficult to get enough vitamin D from your diet, taking a supplement from November through March—when you won’t be getting as much of the nutrient from sunlight—can help you drop pounds more easily. Not Getting Enough Water: Your body needs fluids to perform all of its functions. When it’s not performing those functions as well, it’s not burning as many calories. Something else to keep in mind: A lot of the calorie burn from drinking water comes from your body working to bring cold water to 98.6 degrees—so drinking hot water with lemon or hot tea all the time won’t be as good at boosting your metabolism as cold water will. Too Much Cardio: You know that exercise is crucial for keeping your metabolism fired up, but if you swear by running or indoor cycling—and only running or indoor cycling—you’re not building the lean muscle that’ll really give your metabolism a boost. Start incorporating strength training into your workouts to up your calorie burn even more. If you commit any of these crimes against metabolism, identifying them can help you combat them and keep your body in tip top shape.
