As we age, we tend to become more insulin resistant which can put us at risk for type 2 diabetes. When you eat foods that break down into sugar, the pancreas pumps out insulin to escort the sugar out of your blood. People with Insulin resistance don’t use insulin effectively so that cells have trouble absorbing sugar which causes a buildup of sugar and insulin in the blood. Researchers still aren’t 100% in agreement as to why, but at the end of the day, people with insulin resistance gain weight, particularly around the middle. And some research shows that lack of estrogen may cause insulin resistance.
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.
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.
Very soon, I’ll stand up in front of the graduating class of my former high school and give the commencement speech. I’ll focus on the usual “work hard” and “follow your dream” themes, but, in reality, I just want to shout out to all those 17-year-olds — “have that ice cream cone, you’ll still fit into your skinny jeans tomorrow! ” Or “it’s OK to skip a workout, your muscle mass will help you bounce back!”
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
Focusing on being healthy means getting about 30 minutes of moderate exercise every day. This level of exercise can keep your heart healthy and work on things like lowering your cholesterol and/or blood pressure. This is a great place to start if you're getting into exercise after a long break. There's no reason you can't start here and progress to more intense goals as you build strength and endurance.
If you were very active in your younger years, you may have had some injuries. Like a spicy pepperoni pizza does after dinner, those injuries from your carefree days can come back to haunt you. These ghosts of injuries past show up in the form of early arthritis, bone spurs, tighter muscles, pinched nerves, etc. After our 30’s, new injuries also take longer heal. No wonder we slow down.
Non-starchy vegetables, particularly greens, are rich in nutrients, minerals, antioxidants, and fiber, and quite low in calories. They can nourish your body while helping you lose weight.

If you are taking the appropriate measures (e.g., eating enough of a calorie deficit for your age and body composition, stressing less, and working on strength training) and still not losing weight, and you also have other symptoms of hypothyroidism (such as constipation, fatigue, dry hair and nails), then it may be worth considering getting your thyroid levels checked," advises Dr. Peterson.
There appears to be a connection between estrogen and body weight regulation. With lower estrogen levels, lab animals tend to eat more and be less physically active. Levels that are too high or too low appear to lead to fat storage. And, lower estrogen levels may also slow down your metabolic rate (the speed at your body converts stored energy into working energy).
What does that mean for you? That the weight loss process naturally becomes harder as you get older...that's just a fact and accepting it means you can stop punishing yourself or feeling ashamed about your body. Instead of focusing on the negative, focus on the things you can control: Your workouts, activity levels, diet, stress management, sleep management and, most important, your attitude.
