We envy the 140-pound runner because we think she has a fast metabolism. We pity the 350-pound powerlifter, believing he has a slow one.<\/p>\n<p>In truth, the metabolism is less like an engine and more like a thermostat, heating up and cooling down in response to choices you make and things you do. Four major factors determine its speed:<\/p>\n<ol>\n<li>The most significant factor, by far, is your\u00a0<b><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4535334\/\" target=\"_blank\" rel=\"noopener\">resting metabolic rate (RMR)<\/a>\u00a0<\/b>\u2014 the many processes involved in respiration, circulation, digestion, and other functions that occur, unconsciously, 24 hours a day.<\/li>\n<li>Next up is\u00a0<strong>non-exercise activity thermogenesis (NEAT)<\/strong>, or daily living activities: standing, sitting, typing, walking, cooking, talking.<\/li>\n<li>Next is formal\u00a0<b>exercise,\u00a0<\/b>from gym workouts to weekend runs to sports to <a href=\"https:\/\/www.beachbodyondemand.com\/blog\/yoga52-weekly-yoga-workout-programs\" target=\"_blank\" rel=\"noopener\">yoga classes<\/a>.<\/li>\n<li>Finally, the\u00a0<b>thermic effect of food (TEF)\u00a0<\/b>\u2014 the energy required to\u00a0<a href=\"https:\/\/academic.oup.com\/ajcn\/article\/63\/2\/164\/4650492?login=true\" target=\"_blank\" rel=\"noopener\">break food down into usable parts<\/a>.<\/li>\n<\/ol>\n<p>So if you go for a run, or have a big meal, or <a href=\"https:\/\/www.beachbodyondemand.com\/blog\/is-walking-cardio\" target=\"_blank\" rel=\"noopener\">take a walk<\/a>, your metabolism speeds up in response to your muscles\u2019 and your digestive tract\u2019s need for fuel. If you sit down to rest or skip a meal, it slows down.<\/p>\n<p>So our assumptions about the metabolisms of our different-sized athletes, then, is backward: Assuming they\u2019re both in homeostasis \u2014 neither losing nor gaining weight \u2014 the 350-pound strongman, who eats everything in sight, has a much faster metabolism than the 140-pound runner, who watches every bite. The bigger athlete churns through calories while the smaller one uses relatively few of them.<\/p>\n<p>One final factor influencing the speed of your metabolism is age. Most people believe that older people gain weight because they have slower metabolisms than younger ones.<\/p>\n<p>So is it true?<\/p>\n<h2>How Much Does Your Metabolism Slow With Age?<\/h2>\n<p><a href=\"https:\/\/bod-blog-assets.prod.cd.beachbodyondemand.com\/bod-blog\/wp-content\/uploads\/2023\/08\/17092535\/at-what-age-does-metabolism-slow-down-600-age.png\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-164077\" src=\"https:\/\/bod-blog-assets.prod.cd.beachbodyondemand.com\/bod-blog\/wp-content\/uploads\/2023\/08\/17092535\/at-what-age-does-metabolism-slow-down-600-age.png\" alt=\"Mann eats protein bar | At what age does metabolism slow down\" width=\"600\" height=\"400\"\/><\/a><\/p>\n<p>Some metabolic processes do, indeed, slow down with age. A study conducted on men showed that your\u00a0<i>sodium-potassium pumps<\/i>, which play a role in muscle contraction, slow down about\u00a0<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/8386182\/\" target=\"_blank\" rel=\"noopener\">20 percent,<\/a>\u00a0resulting in about 100 fewer calories burned per day.<\/p>\n<p>Simultaneously, the\u00a0<i>mitochondria \u2014\u00a0<\/i>your cells\u2019 engines \u2014\u00a0<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4779179\/\" target=\"_blank\" rel=\"noopener\">lose some of their efficiency<\/a>, resulting in a slower caloric burn than you had at 18 or 20.<\/p>\n<p>But these processes play a far smaller role in metabolic rate than the factors listed above \u2014 no matter how old you are. Another\u00a0<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC2692620\/\" target=\"_blank\" rel=\"noopener\">study<\/a>\u00a0compared the resting metabolic rates of people of various ages. And while it found that the youngest people tested burned more calories per day than the oldest ones, it also found that if you controlled for differences in gender, muscle mass, and fat, the difference decreased.<\/p>\n<h2>Can You Change Your Metabolism?<\/h2>\n<p><a href=\"https:\/\/bod-blog-assets.prod.cd.beachbodyondemand.com\/bod-blog\/wp-content\/uploads\/2023\/08\/17092725\/at-what-age-does-metabolism-slow-down-600-high-five.jpg\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone wp-image-164081\" src=\"https:\/\/bod-blog-assets.prod.cd.beachbodyondemand.com\/bod-blog\/wp-content\/uploads\/2023\/08\/17092725\/at-what-age-does-metabolism-slow-down-600-high-five.jpg\" alt=\"Athletes of Different ages high five | At what age does metabolism slow down\" width=\"600\" height=\"400\"\/><\/a><\/p>\n<p>The message is clear: If you want to keep your metabolism humming along as you age, keep moving! Maintain a formal exercise program, and, if possible, take up active hobbies as well. The more you move in the gym and out of it, the faster your metabolism hums along. So fall in love with moving early, and keep it up for life.<\/p>\n<p>Perhaps the best way to stoke the metabolic fire is with <a href=\"https:\/\/www.beachbodyondemand.com\/blog\/strength-training-for-beginners\" target=\"_blank\" rel=\"noopener\">strength training<\/a>, which can help combat age-related muscle loss which can then be associated with metabolic slowdown. Next up in importance is <a href=\"https:\/\/www.beachbodyondemand.com\/blog\/what-is-cardio\" target=\"_blank\" rel=\"noopener\">cardiovascular activity<\/a>, which helps burn fat and gives your metabolism a daily kick. Finally, if you can get to it, increase your NEAT with daily walks and physical hobbies like gardening.<\/p>\n<p>You can also (minimally) increase the thermic effect of food by consuming <a href=\"https:\/\/www.beachbodyondemand.com\/blog\/lean-protein-foods\" target=\"_blank\" rel=\"noopener\">protein-rich foods<\/a>. Animal products and <a href=\"https:\/\/www.beachbodyondemand.com\/blog\/10-great-vegetarian-sources-protein\" target=\"_blank\" rel=\"noopener\">high-protein vegetarian sources<\/a> like black beans require\u00a0<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4258944\/\" target=\"_blank\" rel=\"noopener\">more energy to digest than carbohydrates and fats<\/a>, which require much less. So emphasize protein in your diet for an additional metabolic boost.<\/p>\n<p>While we are still exploring the factors that cause your body to burn slightly fewer calories as you age, you can potentially mitigate this slowdown with the right <a href=\"https:\/\/www.beachbodyondemand.com\/blog\/weight-loss-workout-plans\" target=\"_blank\" rel=\"noopener\">exercise program<\/a>. A slow metabolism in your later years isn\u2019t inevitable \u2014 but it\u2019s up to you to prevent it.<\/p>\n<\/p><\/div>\n<div data-type=\"_mgwidget\" data-widget-id=\"1675549\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n\n","protected":false},"excerpt":{"rendered":"<p>Not so fun fact: Your metabolism slows down as you age.
