Guys often wonder whether a dip in testosterone is at the root of their weight gain, says Dr. Stanford. "When men develop overweight and obesity, they tend to have a drop in testosterone that leads to a drop in energy and more retention of adipose tissue,” she says. The excess adipose tissue drives testosterone down. But taking testosterone isn’t usually the answer. “That’s not the underlying problem. Once we normalize the weight, the testosterone normalizes," she explains.
Your body has to work harder (meaning it burns more calories) digesting protein than it does fat or carbs, so Palinski-Wade recommends the strategy of upping protein intake to many of her clients, including women who are 40 and over. "Although I don’t promote very high-protein diets, increasing your protein intake from 15 percent of your total calories to 30 percent can help you boost the calories your body burns during digestion, which may just help speed weight loss."
Your metabolic rate naturally continues to decline 5 percent each decade once you hit 40.3 Your resting metabolic rate (RMR) determines how many calories you just to survive. It is determined by a variety of chemical reactions inside your body. These reactions rely on your mitochondrial function and sodium-potassium pumps. Your mitochondria help to create energy, while your sodium-potassium pumps generate muscle contractions and nerve impulses.4,5,6,7,8 Both of these processes become less effective over the years and slow your metabolism.9,10 If you eat more than your RMR yet lead a sedentary life, you set yourself up for weight gain.
"One of the reasons that it's difficult to lose weight in your 40s is that you are beginning to lose muscle mass, so the composition of your body tissue changes," explains Keri Peterson, MD, Women's Health advisor. "Having higher muscle mass raises your metabolism, so your body burns more calories." So when you're dealing with the opposite—less muscle mass—that means a slower metabolism. Argh.
Focusing on being healthy means getting about 30 minutes of moderate exercise every day. This level of exercise can keep your heart healthy and work on things like lowering your cholesterol and/or blood pressure. This is a great place to start if you're getting into exercise after a long break. There's no reason you can't start here and progress to more intense goals as you build strength and endurance.
“There are many eating patterns that can be used to lose weight,” says William Samuel Yancy, M.D., director of the Duke Diet and Fitness Center and associate professor of medicine at Duke University. Many have evidence behind them, whether that’s keto, Paleo, Mediterranean, vegan, or anything else. Interestingly, there’s not as much research on what works for men as there is on women, but “for men, sometimes it’s as simple as shortening the time in which you are eating to an 8- to 10-hour window a day,” says Kristin Kirkpatrick, R.D.N., consultant for Integrative and Lifestyle Medicine for the Cleveland Clinic. Even something as straightforward as not eating after 6 PM can make a big difference—one of her male clients who lost 150 pounds found that to be especially helpful, she says.
Another great idea it to get into a group fitness strength training class. This is a less intimidating way to get started and in most gyms you will find people of all ages and abilities attending; just ask the instructor if it is the right level for you. Strength training at home is another possibility. By joining GHU TV you are spending a minimal amount and getting the personal training of experts like Chris Freytag and others who will do the workout with you providing the expertise needed to do it correctly! Just pick up a pair of dumbbells, bring them home and get started. Keep in mind that if you are afraid to pick up the weights you can even use your own bodyweight to build strength through moves like push-ups, lunges and squats. Strength training for as little as 20 minutes two to three times a week can build enough muscle to increase your resting metabolic rate (RMR) over time.
Very soon, I’ll stand up in front of the graduating class of my former high school and give the commencement speech. I’ll focus on the usual “work hard” and “follow your dream” themes, but, in reality, I just want to shout out to all those 17-year-olds — “have that ice cream cone, you’ll still fit into your skinny jeans tomorrow! ” Or “it’s OK to skip a workout, your muscle mass will help you bounce back!”
Between desk jobs, commutes, and family activities, many 40-somethings don’t have a lot of free time to work out. But it’s important -- for your weight and your overall health -- to fit in at least 2 1/2 hours of moderate physical activity (like brisk walking or light yard work) every week. Pencil times in to your calendar, and make them a priority.
