Let's get down to business: If you're having a hard time achieving your weight-loss goals after 40, these 16 expert-backed tips for losing weight in your 40s are totally doable and can nudge your body in the right direction again. (And, tbh, they're wise for anyone looking to move the needle to keep in mind—not just those over 40.) You'll be on your way to a stronger, healthier you in no time.
For a sustainable plan, "I don't like to hyperfocus on calories. It's important to have a high-quality diet of lean protein, whole grains, and fruits and vegetables," Dr. Stanford says. "Processed foods lead to weight gain, so the less processed the food you eat, the better." And the more satisfied you could end up being. Her example: A nice meal of salmon plus some grains and a vegetable and a salad can give you a lot more volume than a Shake Shack stop would, and would give you more of a sense of being full afterward. When it comes to the high-quality diet she advocates, "nothing is bizarre—we know that lean protein, whole grains, fruits, and vegetables are constant no matter how the guidelines for healthy eating have changed over the years," she says.

It's a myth that eating at night leads to weight gain, Palinksi-Wade points out; it's more about what you're eating at night that can be an issue when it comes to weight management. "Since most of us don’t have a salad for a midnight snack, if you find you tend to eat calorie-dense, high-sugar foods in the evening (like a bowl of ice cream) setting guidelines as to when to stop eating may help you to lose weight faster."
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!)

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.
“Instead of eating less of everything and feeling deprived, you want to replace more calorie-dense foods, such as fried foods, high-fat meats, cookies, cakes, candies (and) chips, with nutrient-rich, less calorie-dense foods, such as vegetables, fruits, salads, bean dishes, broth-based soups and whole grains like oatmeal,” said Kushner, adding that the high water and fiber content of foods like these increase their volume, making them more satisfying for fewer calories.
At 41, these are the things that I notice the most. My body does not bounce back as easily as it once did and I have to work a lot harder to manage my weight. Genetics play a role in the aging process, but our lifestyle choices can help dictate how well our genes treat us as we get older. After turning 40, these are six of the top lifestyle habits to focus on.
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.
