Work with your body, not against it, for long-term weight maintenance.

For many people, their New Year's resolutions include some sort of weight-loss goal. However, while extra pounds often come off, evidence shows they rarely stay off. Among overweight or obese people who are able to lose 10% of their body weight, just one in six is able to maintain the weight loss for at least a year.

Experts say it's not surprising that weight loss rarely sticks, considering what they now know about how the body works. "Most people believe that obesity is caused by overeating, while we now recognize that the main driver of obesity is one or more disruptions in the body's normal regulation of the amount of fat we maintain," says Dr. Lee Kaplan, an associate professor of medicine at Harvard Medical School and director of the Obesity, Metabolism, and Nutrition Institute at Massachusetts General Hospital.

After everything that has happened in 2020, making New Year’s resolutions might be too much to expect of many. Setting goals for the coming year seems like too much to ask right now. Is it okay to just give yourself a break this year? Or is there another way of looking at the whole situation?

Learn when, how, and why you should keep track of your heartbeat.

Soon after you wake up tomorrow morning, before you even sit up in bed, take your pulse. It's fairly easy if you have a clock or timer nearby (see "Measuring your heart rate"). Known as your resting heart rate, this value ranges from 60 to 100 beats per minute in most adults.

"To get a good sense of your resting heart rate, check it every few mornings over the course of several weeks," advises cardiologist Dr. Aaron Baggish, director of the Cardiovascular Performance Program at Harvard-affiliated Massachusetts General Hospital. It's best to measure your resting heart rate when you've been getting your typical amount of sleep and exercise and aren't feeling ill or dehydrated.

No matter what your age, you can improve your fitness.

If it's been a long time since you've exercised and you're feeling less than fit, you might think that it's too late to make a change. But you're wrong. You can improve your fitness at any age.

"The stories in this area are actually very dramatic. Even people 100 years old or older can build muscle strength," says Dr. Edward Phillips, assistant professor of physical medicine and rehabilitation at Harvard Medical School.

Research we're watching

Good news if you take a more leisurely approach to your workouts: a recent study found that people who performed harder workouts didn't live any longer, on average, when compared with people who did more moderate workouts. Researchers studied a group of people in Norway who participated in five years of supervised exercise training. The participants included 790 women and 777 men (with an average age of 73), divided into three groups. Everyone followed federal recommendations to get 30 minutes of moderate exercise on most days of the week. But in addition to that, one group received two supervised weekly sessions of high-intensity interval training. A second group added two supervised moderate-intensity continuous training workouts per week. All three groups continued their assigned workouts for five years.

At the conclusion of the trial, 4.6% of the participants had died, but there was no significant difference in death rates between the group that followed the modest federal exercise recommendations and the two groups that did the more intense workouts. In addition, all groups had similar levels of cardiovascular disease and deaths from cancer. However, that's not to say that participating in regular high-intensity workouts wasn't linked to any benefits. The participants who did the harder workouts had better outcomes on certain measures of mental health and physical fitness.

Walking even at a "casual" pace — covering a mile in 30 minutes — five days a week may lower the odds of high blood pressure in postmenopausal women, a new study finds.

Researchers relied on data from more than 83,000 women ages 50 to 79 who did not have high blood pressure. When they joined the study, they filled out questionnaires about their walking speed and duration. This was followed by yearly questionnaires that included checking for a diagnosis of high blood pressure.

If you've been diagnosed with heart disease, the FITT approach can reduce your risk for heart attack and stroke.

About half of all Americans have at least one of the key risk factors for heart disease, such as high cholesterol, high blood pressure, and excess weight.

You can address those risks with a heart-healthy diet and medications to lower blood pressure and cholesterol levels. But perhaps the biggest boost you can give your heart is regular aerobic exercise.

Schedule shifts can hurt your health. The New Year is a great time to hit the reset button.

Throughout most of human history, the pattern of daily life was regular. Dreary for many, but regular. In recent centuries, "modern" life has introduced many irregularities, including changing work schedules. Advances in information technology mean that many of us are always connected — and that we spend time connecting at all hours. And the COVID-19 pandemic has introduced whole new irregularities into daily life.

One thing is certain: "When your schedule changes, you can lose the regular self-care routines that kept you active, eating right, and managing stress — things we need to control weight and inflammation and fight disease," says Dr. Monique Tello, a primary care physician and healthy lifestyle specialist with Harvard-affiliated Massachusetts General Hospital.

Make this year's batch of New Year's resolutions stick by taking a new approach.

It's a new year, and you've got a resolution in mind. Whether it's aiming for a healthier diet, improving your stress management, or finally committing to that daily workout, achieving your goal probably won't be easy. Resolutions made on New Year's Day are often in the trash bin by Valentine's Day. But this year can be different if you learn how to COACH yourself to success.

Dr. Beth Frates, an assistant professor of physical medicine and rehabilitation at Harvard Medical School, designed a strategy she calls COACH to move you toward your goals. It's a process that can help sidestep pitfalls that may have derailed you in the past.

Make sure it's tailored to your needs and has the elements that are essential for health and safety.

You've resolved to exercise more, and you're looking for an online exercise video that will help you achieve your fitness goals. That's a great start, but there's more to choosing an exercise video than simply finding workouts that appeal to you. "Online exercise videos aren't regulated. And trying to keep up with a workout that isn't designed for older adults could lead to injury," says Dr. Edward Phillips, assistant professor of physical medicine and rehabilitation at Harvard Medical School and Whole Health medical director at VA Boston Healthcare System.

Where to start

YouTube is a rich resource for effective exercise videos. You can find workouts designed for older adults from hospitals, government health agencies, academic centers (including Harvard Medical School), personal trainers, and senior centers. However, YouTube also contains scores of workout videos that could be risky for older adults. So it takes work to find a workout tailored to your needs.
