FDA warns against using these smart gadgets to measure blood sugar

Weighing the dangers of extra weight

Standard definitions consider a healthy body mass index (BMI), a calculation based on a person's height and weight, as between 18.5 and 24.9. Studies have found that a higher BMI increases risk for heart disease, diabetes, and some types of cancer. However, even if their BMI does not fall into the category of overweight, people who gain five or more pounds may be at risk for health problems, especially if the weight gain is belly fat. The best approach is a combination of aerobic exercise, strength training, and a healthy diet.

Alert: This hidden condition increases heart attack and stroke risks

Metabolic syndrome is a constellation of interrelated health conditions that significantly increases the risk for heart attacks, strokes, diabetes, and more. A diagnosis requires at least three of the following risk factors: obesity, high blood sugar, high triglycerides, low HDL (good) cholesterol, or high blood pressure. Metabolic syndrome can be reversed if it's recognized. Losing weight is central to reducing many of its features. Lowering elevated blood pressure, blood sugar, and cholesterol levels also plays a major role in reducing the risk for heart disease and stroke.

Will walking faster reduce your diabetes risk?

A 2023 study found that compared with "casual" walking (at less than 2 mph), walking 2 mph to 3 mph (brisk walking) was associated with a 15% lower risk of diabetes, no matter how long people walked each day.

Anti-obesity drug lowers heart-related problems

The weight-loss drug semaglutide is the first obesity treatment shown to help people live longer and have fewer cardiovascular problems. Developed as a drug for type 2 diabetes, semaglutide was first marketed as Ozempic; a higher-dose version for weight loss is called Wegovy. But because the drug is so popular, it can be hard to find, and it might not be covered by insurance.
