Do gut bacteria inhibit weight loss?
Ask the doctor
Q. I just can't lose weight. A friend says that my problem might be due to the types of bacteria that live in my gut. That sounds crazy to me, but is it true, and can I do something about it?
A. Ten years ago, I also would have thought your friend was crazy. Today, I'd say she could well be right. Here's why. We've known for a century that bacteria live in our intestines, but we've assumed that they did little to affect our health. We thought that they were just mooching off of us — taking advantage of the warmth and nutrients in our gut.
Does apple cider vinegar have any proven health benefits?
On call
Q. I have heard a lot about how apple cider vinegar can help improve one's health. Is there anything to this?
A. As with so many dietary fads, apple cider vinegar has seen its share of health claims with little medical evidence to support them. The studies exploring its health benefits have focused on reductions in blood sugar levels and weight loss, but these have been small, short-term trials or animal studies.
Can taking aspirin regularly help prevent breast cancer?
Experts say there's little evidence that low-dose aspirin therapy brings benefits, and there are some risks.
In recent years, there's been a lot of talk about the potential benefits, and risks, of a regular regimen of low-dose aspirin. While much of the discussion has centered on whether taking low-dose aspirin can head off cardiovascular disease, some of the focus has also been on breast cancer. Can regular doses of this over-the-counter pain reliever reduce your risk of this common cancer?
For a while there were hints that the evidence was leaning that way. Back in 2017, this area of research, while still inconclusive, was somewhat promising. For example, a 2017 study published in Breast Cancer Research found that among some 57,000 women, those who reported taking low-dose aspirin (81 mg) at least three times a week had a 16% lower risk of breast cancer over all and a 20% lower risk of a specific type of hormonally driven breast cancer.
Can you supercharge the Mediterranean diet?
News briefs
A Mediterranean-style diet is rich in vegetables, legumes, fruits, whole grains, nuts, seeds, poultry, fish, and olive oil, and it's associated with lower risks for heart disease and diabetes. And a "greener" version of the eating style might be even more effective, according to a small, randomized study published online Nov. 23, 2020, by the journal Heart. Researchers — some from Harvard — recruited about 300 sedentary, middle-aged people (mostly men) with high cholesterol or abdominal obesity and divided them into three groups. One received guidance for exercise and a healthy diet; another received exercise guidance and was assigned to eat a calorie-restricted Mediterranean diet; and one group received exercise guidance and was assigned to eat a "greener" calorie-restricted Mediterranean diet with less animal-based and more plant-based proteins (including walnuts and a type of duckweed — an aquatic plant), plus lots of green tea. After six months, people on the "green" diet had lost more weight and inches around their middles, and had bigger drops in cholesterol, than people in the other two groups. "Green" dieters also had steeper declines in insulin resistance, inflammation markers, and diastolic blood pressure (the lower number in the measurement), compared with the other two groups.

Cohabitating couples share heart-related habits, risks
Research we're watching
Couples who live together tend to have similar health habits. But only about one in five couples falls into the "ideal" category for heart-healthy habits and risk factors, suggests a study in the Oct. 26, 2020, issue of JAMA Network Open.
Researchers looked at health data on 5,365 couples from diverse racial and economic backgrounds throughout the United States. Most were in their 40s and 50s. Based on risk factors from the American Heart Association's Life's Simple 7 (smoking status, body mass index, exercise, diet, total cholesterol, blood pressure, and fasting blood sugar), researchers categorized individuals and couples as poor, intermediate, or ideal for each factor and over all.
Bad habits come in pairs
Your partner's flawed health behaviors may be harming your heart.
It's been said that the longer couples stay together the more they look alike. As it turns out, the resemblance may be more than skin-deep. A study published online Oct. 26, 2020, by JAMA Network Open found that couples' health behavior and heart disease risk factors also look alike — for better or worse.
"We know, even from personal experience, that couples share similar behaviors that can affect health, but it was surprising to find the high levels of shared unhealthy behaviors within couples," says the study's lead author, Dov Shiffman, a senior scientific fellow at the medical testing company Quest Diagnostics.
Tips to keep lost weight off in the New Year
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.
Obesity is still on the rise among American adults
Research we're watching
American adults are gaining weight, according to data from the CDC. Twelve U.S. states now have obesity rates of 35% or higher, compared with just six states in 2017 and nine states in 2018. Experts say the trend is particularly concerning because adults with obesity are more prone to severe outcomes from COVID-19.
According to the CDC report, racial and ethnic minority groups are disproportionately affected by obesity. Prevalence rates nationwide were
How can I cut down on sugar in my diet?
Ask the doctors
Q. I'm trying to eat less sugar. Can you offer any tips that can help?
A. First, congratulations. Cutting down your consumption of sugar can help protect your health in the long term. Sugar-heavy diets have been linked to health conditions, including obesity, diabetes, and heart disease. Most Americans eat far too much sugar. A U.S. government health and diet survey from 2015–16 found that the average American eats about 17 teaspoons of sugar a day. The Dietary Guidelines for Americans recommend eating no more than the equivalent of 12 teaspoons of sugar a day, and the American Heart Association suggests no more than the equivalent of six teaspoons per day. To cut down on your sugar consumption, your first goal should be to focus on incorporating more whole, unprocessed foods into your daily diet. Eating more of these foods can crowd out processed sources of added sugars in your diet.
Is there a cure for my nightly snoring?
Ask the doctors
Q. My partner says I've been snoring lately. Are there any home remedies I can use to help me stop?
A. Snoring occurs when muscles in your airway relax during sleep, narrowing the airway and making your breath sounds louder as the air forces its way through. There are a number of strategies that can help. Try sleeping on your side instead of your back, which pushes your tongue to the back of your mouth. Clear nasal congestion resulting from allergies or a stuffy nose. Avoid alcohol (which may act as a sedative) and sleep medications known as benzodiazepines, which may cause your airway tissues to relax, making snoring worse. Losing weight can also help, because surplus tissue, caused by weight gain, can put pressure on and compress the airway, making snoring worse. However, if your snoring does not improve, your partner notices that you have periods during the night where your breathing Âappears to stop, or you regularly feel drowsy during the day, it may be time to pay a visit to your doctor. You could have a condition called obstructive sleep apnea, which may require treatment.
