Exercising more without eating less is often unsuccessful for people trying to lose weight. Despite this, exercise can still improve blood pressure and cholesterol levels.
A 2026 review found conflicting evidence regarding the links between cannabis and heart-related problems, including heart attacks, stroke, coronary artery disease, and heart failure. The most consistent association was between cannabis use and heart rhythm problems.
People who have a low coronary artery calcium score (between 1 and 99) have signs of early heart disease. Current guidelines recommend taking a statin, with a goal of lowering LDL cholesterol by at least 30%.
A small, short-term 2026 study suggests that people who schedule their exercise to align with their chronotype—the body’s natural sleep and wake cycle—may lower their heart risk factors more than those who exercise at times that don’t align with their chronotype.
Heart block is a slowdown or blockage of the electrical signals that travel from the upper to lower chambers of the heart. People with third-degree heart block (the most serious form) nearly always need a permanent pacemaker.
Early detection of colorectal cancer saves lives. Now there are more ways than ever to get screened (and fewer excuses not to). American Cancer Society screening guidelines now include colonoscopy, sigmoidoscopy, CT scanning, at-home stool testing, and blood testing.
A major Harvard study adds more evidence that a healthy diet may protect your brain. Older adults who ate the most ultra-processed foods were found to have substantially higher risks of dementia and cognitive decline, while those eating more minimally processed foods had lower risks.
The DASH diet is a flexible, science-backed eating plan proven to lower blood pressure, while also reducing risks of heart disease, diabetes, cancer, and cognitive decline. Emphasizing vegetables, fruits, whole grains, and low-fat dairy products, it’s a healthy way to eat that suits almost everyone.
For people managing a chronic illness or recovery, medically tailored meals—home-delivered and dietitian-planned—can help. Research shows they improve health outcomes, reduce hospitalizations, and save billions in health care costs. Programs range from full meal delivery to grocery boxes and produce vouchers.
Creating a calorie deficit—burning more than one consumes—is the foundation of sustainable weight loss. “Slow and steady” is best: experts recommend a 500-calorie daily deficit for gradual progress, combined with regular physical activity, especially strength training.
