The pleasure of eating a candy bar lasts but a few minutes. Burning off the calories it delivers can take nearly an hour. So this is definitely not a simple way to lose weight! 

To lose one pound by exercising, you need to burn approximately 3,500 calories. It can take days of moderate exercise to do this. A better strategy for weight loss involves a two-pronged approach: exercising and cutting calories.

Weight loss can be challenging, but there are some strategies for success.

If you're struggling to lose weight, you probably feel like the odds are stacked against you. You're not necessarily wrong.

"There is so much great-tasting food, and it's abundant and in your face all the time. To me it's kind of a miracle that people aren't even heavier than they are," says Dr. Meir Stampfer, a professor of epidemiology and nutrition at the Harvard T.H. Chan School of Public Health. In addition to an abundance of food, most people today also have a far more sedentary lifestyle than past generations. "Even active people who exercise a lot aren't expending the calories their ancestors did," says Dr. Stampfer.

Q. I have just recovered from the flu. How soon can I resume exercise again and can I go straight back to my previous routine?

A. The recommendations about when to return to exercise after respiratory infections, such as the flu, colds, or bronchitis, are vague. One major reason is that each person's response to illness is so variable. But here is my general advice.

Most children and teens who have COVID-19 recover completely, but rarely there can be damage to a child’s heart muscle, and the stress of exercise on a damaged heart could lead to a serious condition. Here’s what parents need to know about recent guidance from the American Academy of Pediatrics for children returning to physical activity after COVID-19.

For a long time, the implicit message about fitness has been that it only counts if you are doing it with certain clothing, shoes, equipment, and facilities. This can make people feel that exercise is not for them. Expanding the idea of what counts as exercise — and making it fun — can help motivate people.

Research we're watching

There are a number of different approaches to treating a condition called adhesive capsulitis, better known as frozen shoulder. This common condition causes significant shoulder pain and reduced mobility. While it generally goes away on its own over time, it can take up to a year or longer to heal. But there hasn't been consensus on whether any particular therapy leads to more rapid pain relief and full range of motion.

A study published online Dec. 16, 2020, by JAMA Network Open looked at various treatment options for frozen shoulder to determine which was the most effective. Researchers analyzed 65 different studies with more than 4,000 total participants and found that the first line of therapy should be to inject a steroid directly into the joint to reduce inflammation. This treatment helped to reduce pain and led to the fastest recovery. The study authors said the steroid injection should be accompanied by a home exercise program that includes stretches and exercises to improve range of movement in the shoulder.

How much weight, how many reps and sets, and how often? Here's what new guidelines suggest.

Old-fashioned resistance training — lifting heavy weights multiple times — is the best way for men to slow and even reverse age-related muscle loss, known as sarcopenia. It can also increase your strength, protect against falls, and help you live a more independent life.

Resistance training (also known as strength training) consists of doing upper- and lower-body exercises using free weights (like dumbbells, kettlebells, or barbells), weight machines, resistance bands, or just your own body weight.
