People naturally lose muscle after 40, especially women after menopause. Because muscle burns more calories than fat, this can slow down your metabolism and make it harder to shake those stubborn pounds. Strength-training exercises -- lifting weights or doing body-weight exercises, like push-ups and squats -- at least twice a week can help you keep those muscles.
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.
Oxidative stress occurs when the balance between free radicals in the body and our ability to fight against them is uneven, with free radicals prevailing. Free radicals can cause disease and there is an association with an increased risk of formation of free radicals as we age. That's why after a certain age, building up our defenses (through having lots of antioxidants in plants) can help reduce this imbalance and stack the cards in our defense system instead.

Sometimes the medicines you're taking for other issues, such as high blood pressure and antidepressant meds, can increase your weight or keep you from losing it, says Dr. Stanford. Ask your doctor if your weight concerns could be side effects of the prescriptions you're getting filled. Often, there are other formulations that can be effective but wouldn't have those side effects for you.
If you're genetically predisposed to gain weight easily, that may be another strike against you. Even if you don't actually gain weight, you may still gain inches around the waist. This weight gain can be so frustrating, it's easy to become obsessed with losing it, starving yourself or exercising too much or maybe even looking into the latest plastic surgery procedure.

While it seems like ankle weights should help our leg muscles tone faster than without the weights, our legs aren’t designed to carry around heavy feet. There is more risk for injury of tendons and ligaments than toning leg muscles. If you want to focus on leg toning, your best option is some body weight workouts or exercises such as lunges with weights.
To jumpstart your weight loss, the biggest focus should be to develop habits that will help you build or maintain your muscle mass. "The most effective way that women over 40 can boost their metabolism is by building muscle through weight-lifting and resistance training," says Dr. Peterson (more on that to come). But nutrition and sleep habits also play a role here.
Good stress management techniques and routine exercise will have positive effects on your sleep, but you may need to take additional steps to help you sleep better. For example, be proactive about going to bed and waking up at the same time most days, and allow yourself 30 minutes to unwind and disconnect from your digital devices at night. Eating a plant-forward, mostly whole foods diet that’s low in added sugar helps, too.

Alcohol adds unnecessary calories and sugar to your diet. Drinking alcohol may also increase your appetite, leading you to consume more calories.30 When you’re under the influence of alcohol, you may also be tempted to choose less nutritious options, such as processed junk foods. I recommend reducing your alcohol consumption to an occasional glass of wine or eliminating it completely.


Hormonal changes are one of the main reasons that women tend to lose more muscle as they approach menopause. Diet and exercise also play a role.12 On average, adults lose 3 to 8 percent muscle every decade after age 30.13,14 By the time you reach 80, you may have about 30 percent less muscle than you had at age 20.15,16 Muscle loss over time can lead to slower RMR, increased fat, weight gain, weakness, and fractures.17
"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.
Why that’s so important: “The more muscle we have, the more calories we burn,” Kirkpatrick says. Even if it doesn't actually help you lose weight, it can help keep you from gaining it—along with all the other good things it does for your body, mind, and life. Lots of over-40 guys like HIIT, since its compressed timeframe ends up having a low impact on your schedule.
As you reach mid-life, the pressures pile up. Just think of the typical stressors, like caring for kids and aging parents, facing financial burdens and dealing with the demands of a job. When you’re experiencing stress, your body responds by releasing the hormone cortisol. If your stress diminishes, your hormone levels return to normal, but if you’re experiencing ongoing stress from “adulting,” cortisol levels will remain high. This can set off a series of biological events that may lead to an increased appetite with more cravings and a propensity to store fat in your belly.
Eating well isn’t just about skipping out on processed junk food. It’s also about filling up your plate with clean, healthy foods that can actually assist in your weight loss. Healthy fats like those found in olive oil, avocados and nut butters nourish your body while helping you feel full longer—which means you’re less likely to overeat. Incorporating healthy sources of protein like eggs and salmon will also help you feel more satiated as well as fuel the muscles you’re building through that regular strength training we mentioned above! Hungry during the day? Keep a small pack of heatlhy almonds or other nuts in your bag to snack on in a pinch.  Just a handful will keep you satisfied until your next meal, all while providing healthy protein, fat and fiber. Don’t wait until you’re tummy is growling! Be prepared.
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.

After turning 40, these are six of the top lifestyle habits to focus on.
