Metformin, a medicine prescribed to treat type 2 diabetes, also has cardiovascular benefits and is used off-label to treat other conditions. Interest is growing in its potential to help lower risks for other serious health problems and even slow aspects of aging, but which of these benefits, if any, apply to people who do not have diabetes?

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.

People who lose weight with a portion-controlled diet and exercise may be able to reverse their diabetes. When that happens, their risk of heart disease and kidney disease declines, according to a 2024 study.

A 2023 study suggests that women who prefer to stay up and wake up later are more likely to develop diabetes and to have unhealthful lifestyle habits compared with those who prefer to go to bed and wake up earlier.

A 2023 study suggests that having diabetes may be tied to a higher risk of developing colorectal cancer than not having diabetes.

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.

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.

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.

A 2023 study suggests that eating more red meat—about a one additional serving each day—is linked to a higher risk of developing diabetes than those who eat less.
