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.
It’s no secret that losing weight after 40 can be difficult for some women. As you age, you begin to lose muscle mass, causing your metabolism to slow down. Add to the slow metabolism a dose of wildly fluctuating hormones and you have the perfect recipe for weight gain. Weight gain after 40 no longer translates into only a tight-fitting pair of pants. You are now at increased risks for a wide range of diseases, including depression, high blood pressure, and diabetes.
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.

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.

"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.
Additionally, attempts to lose weight on low-calorie diets can lead to even more lost muscle. Studies have found that regular resistance or strength training may be a better alternative than your daily runs to preserve and gain muscle — even when coupled with a low-calorie diet. Aerobic exercise is still important, just don’t make it your only form of activity.
As you enter your forties, you are also entering perimenopause, when levels of your sex hormones progesterone and estrogen decline. Besides regulating your menstrual cycle and reproductive functions, these hormones also impact restful sleep and relaxation. A decrease in progesterone and estrogen levels may lead to sleep disturbances, restlessness, and insomnia.1 Because changes in sleep patterns have been associated with weight gain, sleepless nights may make weight loss increasingly difficult.2
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.
High Intensity Interval Training (HIIT) is where you exert maximum effort through quick, intense bursts of exercise followed by short recovery periods, and it’s a great way to amp up your weight loss. If you’re currently only using doing steady state cardio workouts like jogging or elliptical weight loss exercises, for example, you could benefit from incorporating HIIT workouts to your regimen. Because the intervals get your heart rate more elevated, they help you work harder, not longer. Studies show that HIIT also burns more fat than other workouts.

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.
Healthy fats such as avocados, coconut oil, extra virgin olive oil, avocado oil, and ghee have a number of benefits. These include reducing the risk of heart attack, coronary artery disease, high cholesterol, high blood pressure, cancer, diabetes, and metabolic syndrome.23,24,25,26,27 They can keep you satisfied longer, reducing the risk of overeating and snacking. Healthy eating doesn’t mean deprivation! Healthy fats taste good and improve your brain health, and so may help you feel emotionally satisfied, lowering the risk of emotional eating.28

Yeah, you've probs heard that diet tip before—as it's wise for anyone trying to lose weight. Fried foods contain a whole lot of fat and contribute to weight gain—simple as that. But again, in your 40s, you deal with natural physiological changes that make it *even* tougher to shed excess weight, so overdoing it on fried foods has larger consequences. "A 20 year old can get away with eating empty calorie meals. A 40 year old usually cannot on a semi regular basis," Mirkin points out. "Until we are age 20, [our] bodies are building muscle. After age 20, it stops."
8. Sleep more and stress less. Easy, right?  This may be the hardest part.  There are plenty of things you can try.    Melatonin and or magnesium at night.  Massages.  Yoga.  Meditation.  Hot baths before bed.  Black out windows and cooler temperature in your bedroom.  A good shrink.  There’s really no shortage of suggestions.  It may be time to experiment if you’re not getting enough good sleep.

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."
Sleeping enough is important, and if your lifestyle is making you cheat sleep, then think about what you can do to get enough. Sometimes, however, biology is keeping you from enough shuteye, and it's imperative to solve that. "Untreated obstructive sleep apnea can lead to additional weight gain," says Dr. Stanford. If you are making all the right efforts to get restorative sleep and still don't feel restored, consider seeing a sleep doctor, who can drill down on the problem and help you find some solutions.
Changes in your activity levels are one of the main reasons that losing weight after 40 may be more challenging than before. Like many women, you may be putting others first and simply not finding time to exercise. You may also notice that your joints can no longer handle the same activities as before. However, a lack of exercise can lead to muscle loss and fat gain.
In your forties, your body may have an increasingly difficult time digesting carbohydrates, which may lead to weight gain. Living a stressful life can lead to an increase in the stress-hormone called cortisol, which can make you more prone to gaining belly fat. Estrogen loss may also lead to fat redistribution in your body and cause belly fat gain.11

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.
