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.

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.
If you prefer a specific plan with specific rules, make sure it goes with your lifestyle, which, for most guys, gets increasingly complicated in your 40s with more responsibilities at work, with your family, and maybe even with your aging parents. A vegan diet can be hard to do in a healthy way if you live a grab-and-go existence. Meal prep is going to be a challenge if you’re never home long enough to cook. Don’t just pick what worked for a friend; pick what’s likely to work with your busy, over-40 lifestyle.

One of the main culprits for weight gain is, of course, our hormones, which start to change right around the mid-30s and into the 40s. This change in hormones, less estrogen for women and less testosterone for men, cause the fat in our bodies fat to shift to the middle of the body while abandoning other areas of the body you could care less about. That's one reason you may get a little fluffier around the middle while other parts of you actually get smaller.
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.
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.
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.
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.

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.

That delicious plate you just bought or cooked up might temp you to gobble it up in just a few bites, but that's probably not a good idea, says Palinski-Wade. "Eating slowly, eliminating distractions at meals, and even putting your fork down in between bites all allow you to get in touch with your body’s satiety signals and to stop eating when satisfied."

When you were young, you probably didn't spend too much time thinking about preparing your body for the future. In your teens and twenties, you're in peak condition and it's the perfect time to start exercising. Cut to 20 years later and, if you didn't start exercising, you probably wish you had since there's something we all start to experience in our 40's—weight gain.
