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.
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.
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.
Erin Palinski-Wade, RD and nutrition and diabetes expert, adds that you can use fruits and veggies to help exercise portion control, too. "If you aim to fill half your plate with vegetables, it can help you to reduce the portion size of the other foods while feeling just as satisfied," she explains. "And since vegetables provide few calories, this strategy can reduce your overall calorie intake at each meal, helping to promote weight loss.
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.
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

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.
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.
