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.
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.
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.
Before you try anything else, make sure there isn’t an underlying factor interfering with your weight loss, like a thyroid condition. Did you know that nearly 1 in 5 adults over 40 suffer from thyroid problems that can interfere with weight loss? Your thyroid is the main regulator of your body’s metabolism, so having an over or under-active thyroid gland (hyper or hypothyroidism) can truly interfere with weight loss. Talk to your doctor if you’re having trouble losing weight and also experiencing any of the following symptoms of a thyroid disorder:

"And since vegetables provide few calories, this strategy can reduce your overall calorie intake at each meal, helping to promote weight loss.
Soda and other sugary soft drinks are all empty calories that may result in weight gain and health problems. Don’t be fooled—diet soda is not better.

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.
