Hybrid exercise training combines heart-pumping aerobic action with muscle-strengthening moves in the same exercise session. The strategy has the advantage of meeting two key goals of the federal Physical Activity Guidelines in one fell swoop. And it also appears to be one of the best—and most time-efficient—ways for people who are overweight to lower their risk of cardiovascular-related risk factors. Strong muscles boost a person's basal metabolic rate—the amount of energy the body needs to keep working during rest. That improves weight-loss efforts by ramping up the number of calories burned.

Recent guidelines suggest a blood pressure reading of less than 120/80 mm Hg as normal. But the ideal number for individuals depends on their individual goals and whether they also have a chronic condition, such as heart disease or kidney disease.

Limiting meals to a certain window of time each day, an approach called time-restricted eating, didn't appear to help people lose any more weight compared with ordinary calorie restriction in a small randomized trial published in 2022.

Misperceptions and biases about obesity can derail progress against this common disease, which affects 42% of Americans and is linked to many serious health problems, including heart disease. Bias and stigma against people with obesity is widespread, often due to a belief that poor choices and lack of motivation are the only causes. But a number of interconnected factors are involved, including an obesity-promoting environment, lack of physical activity, genetics, insufficient sleep, mental health issues, and certain medications.

A new study suggests a high-fiber diet may protect against dementia. In a group of about 3,700 older adults, those who consumed the most fiber (about 20 grams daily) had the lowest rates of dementia, and those who ate the least fiber (8 grams daily) had the highest rates.

Aging and a family history can increase the risk for a stroke, but women can lower it by managing factors that are under their control-such as diet, exercise, blood pressure, smoking, and diabetes.

A study published online Jan. 15, 2022, by Appetite suggested that people's expectations of how full they will feel after eating can influence their actual food intake.

People who work the night shift might benefit from eating their meals during daytime hours. A 2021 study found a rise in blood sugar in people following night shift hours who ate some meals at night, but not in those who ate all meals during the day.

Between-meal snacks can either help or hinder people's efforts to eat a heart-healthy diet. Simple strategies such as upgrading food choices can help. Instead of low-quality carbs like candy or potato chips, people should choose high-quality carbs like fruit or whole-grain crackers, along with a little protein or healthy fat (such as half an apple with a handful of nuts). They should also try to avoid eating simply out of habit when they're not actually hungry.
