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.

Are you a woman over 40 and noticing it’s getting harder to lose weight?  Got some extra stubborn fluff and puff around the middle?  Maybe you’re finding that the diets you did in your 20’s or 30’s don’t work as fast as they used to or don’t even work at all!  If you’re already well past 40, chances are you’ve found it’s harder to lose weight.  And, those inches around your waistline won’t budge.

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.
This is a great article. I appreciate all this insight and help as hitting 40 a few years ago was a shock to my body for sure. I would also add to your stress reducing ideas to spend some time reading the Psalms in the Bible. The God who created you longs to take your burdens and teach you how to stop trying to solve all your problems on your own. He is there to show you the way to stress reduction and a while new/better way of doing life. If you don’t know God or how you can start a personal 1-on-1 relationship with Him, check out some of these helpful apps in the App Store: Knowing God Personally (by Power to Change), God Tools (by Cru), Life Conversation Guide (by North American Mission Board), or talk to a pastor at a local Christian church in your neighborhood. My rule of thumb is that while working to take care of my physical body throughout my lifetime, I never want to neglect my soul that will continue on for all eternity.
Hormone imbalance can also wreak havoc on your weight. Keep in mind that perimenopause and other hormone changes can start when you are in your 40s. Estrogen dominance will definitely interrupt weight loss but so will the imbalance of  cortisol, leptin and insulin. We have a great article that covers, in great detail, how these hormones affect your body. Check out Balance These 4 Hormones If You Want To Lose Weight for more information!
"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.
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."
Hi Kathy - You are doing things right - I am a fan of bodyweight and dumbbells while doing HIIT and circuits, etc. You don't need to do the traditional free weight workout... BUT you do want to make sure you are challenging yourself enough to feel your muscles working - if you can go a little heavier, do it! Also - I don't know how much weight you have to lose - if it's only a few pounds - those are the hardest. However, if you have a lot of weight to lose and the scale isn't budging - you are doing a good amount of exercise - I would really analyze what you are eating - that is at least, if not more than 50 % of the equation.

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
“There are many eating patterns that can be used to lose weight,” says William Samuel Yancy, M.D., director of the Duke Diet and Fitness Center and associate professor of medicine at Duke University. Many have evidence behind them, whether that’s keto, Paleo, Mediterranean, vegan, or anything else. Interestingly, there’s not as much research on what works for men as there is on women, but “for men, sometimes it’s as simple as shortening the time in which you are eating to an 8- to 10-hour window a day,” says Kristin Kirkpatrick, R.D.N., consultant for Integrative and Lifestyle Medicine for the Cleveland Clinic. Even something as straightforward as not eating after 6 PM can make a big difference—one of her male clients who lost 150 pounds found that to be especially helpful, she says.
If you're a breakfast person, what you eat in the a.m. can set the tone for the rest of your day as far as weight loss goes (whether you're 40 or not!). "A breakfast rich in lean protein, fiber, and plant-based fats is the best option for curbing hunger and cravings later in the day," notes Palinski-Wade. In other words, start off with a breakfast that fits this bill, and you may end up slashing calories throughout the rest of the day.
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.

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.
