Diet & Weight Loss Archive

Put the focus on food quality and healthy lifestyle practices to attain a healthy weight.

Most people have been taught that losing weight is a matter of simple math. Cut calories — specifically 3,500 calories, and you'll lose a pound. But as it turns out, experts are learning that this decades-old strategy is actually pretty misguided.

"This idea of 'a calorie in and a calorie out' when it comes to weight loss is not only antiquated, it's just wrong," says Dr. Fatima Cody Stanford, an obesity specialist and assistant professor of medicine and pediatrics at Harvard Medical School.

Erectile dysfunction (ED) medications are relatively safe and work for most men, but they aren’t right for every man. Here are six proven strategies that can help –– and offer added benefits on overall health and quality of life.

Studies of drugs, diets, and devices all come with their own unique set of challenges.

The best way to know if a new medical treatment truly works is with a randomized controlled trial — the "gold standard" of research studies, also known simply as a clinical trial. Volunteers are randomly assigned to receive either the new treatment or the comparison, which may be a placebo (an inactive therapy) or a treatment that's already available.

As the nation's top cause of death, cardiovascular disease has been at the leading edge of evidence generation, says Dr. Robert Yeh, director of the Smith Center for Outcomes Research in Cardiology at Harvard-affiliated Beth Israel Deaconess Medical Center. "We probably have more evidence for cardiovascular treatments than for any other field of medicine," he says. Among the studies with the greatest impact were the clinical trials that heralded new therapies to treat heart attacks. These include clot-dissolving drugs in the 1980s, followed in the 1990s by artery-opening angioplasty procedures, which remain the standard of care today. Stents, the tiny mesh tubes used in these procedures, have also been extensively studied in clinical trials (see "Testing devices: Different dilemmas").

Q. I'm hoping to prevent urinary incontinence. Is there anything I can do?

A. Nearly half of all women experience some type of urinary incontinence during the course of their lives. It may not be possible to prevent all of these cases, which can be caused by pregnancy, childbirth, or hormonal shifts that occur around the time of menopause. Here are some strategies that may help to reduce your risk.

Many lifestyle factors can influence the development of atrial fibrillation, and doctors now better understand the importance of these factors in treating afib. Those who are at risk of developing afib can take action to improve their health, and in some cases they may be able to reduce their symptoms.

Want to improve heart health? New research based on blood samples from the original DASH diet shows the DASH diet and another diet high in fruits and veggies can lower measures of heart strain and heart muscle damage within eight weeks.

What you do before procedures can help get the best results.

If you're planning a complex medical procedure or surgery, you'll hear a lot about the steps you'll need to take afterward to speed up recovery and reduce complications. But it's equally important to focus on your health beforehand, too.

"Preparing both your body and mind before an invasive medical procedure can help you better manage and overcome the many stresses you encounter," says Dr. Julie Silver, associate chair for the department of Physical Medicine and Rehabilitation at Harvard Medical School. "If you are healthier and stronger going in, you have a much higher chance of avoiding setbacks."

Prehabilitation aims to increase your strength and health before, not after, a medical procedure.

Rehabilitation can help get you up on your feet again after surgery or a physical setback. But some surgeons are increasingly turning to an innovative approach called prehabilitation in hopes of easing that recovery in the first place.

Prehabilitation, commonly called prehab, is an individualized medical program designed to help people — often those who are older or frail — better withstand and bounce back from an anticipated physically stressful event, such as surgery, says Dr. Julie K. Silver, an associate professor and associate chair of the Department of Physical Medicine and Rehabilitation at Harvard Medical School.

Most diets can help you lose weight, but that weight is frequently regained within a few months — a fact supported by an analysis of more than 100 research trials on diets. But losing weight is easier, and more likely to be permanent, if you choose a diet with foods you actually like.
