Starting in your 30s, you can lose three to five percent of your muscle mass each decade if you don’t stay active. Note the last part of that point: “If you don’t stay active.” As you get older, "there's a lot of competition for your time and energy," says Dr. Yancy. For some men, that can push exercise out of the picture. But it doesn't take heroic efforts to put it back into your life.
Sarah Mirkin, RDN, author of Fill Your Plate Lose the Weight, recommends 20 to 30 grams of protein per meal. "It’s important to take in that amount of protein at all your meals, and ideally include high protein snacks as well," Mirkin says. "This helps to prevent lean muscle protein breakdown that decreases muscle mass percentage, increases fat percentage, and slows the metabolic rate. Muscle burns calories. Fat doesn’t."
2. Exercise More. Contrary to what your body may want to do, you must exercise more regularly as you age, not less! If you’re finding yourself slowing down, gradually start ramping it back up. It’s not a good idea to go from taking an occasional walk to running a 10K. That’s a fast track to getting an injury. But start finding ways to fit more physical activity to your life. The more you exercise, the more insulin sensitive you become (that’s the opposite of insulin resistant!)
Unfortunately, you can't just focus on one area of your body. "Women should focus on all muscle groups in order to lose weight and build muscle because there's no such thing as spot training," Diamond reminds. "With that said, women have a tendency to gain weight in the midsection as we age and focusing on the core and a well-balanced workout will help to reshape body composition."
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!”
If you eat healthy and exercise regularly and still can’t lose weight, your thyroid might not be working like it should. This happens in about 5% of people, and it's most common in women and people over 60. In addition to weight gain, it can also cause fatigue, joint or muscle pain, and depression. Medications can help, so get it checked if you think it might be an issue.
