Discover effective lifestyle changes to reverse metabolic syndrome, improve heart health, and boost well-being through the TLC program.
Metabolic syndrome is a group of health problems that raises the risk of heart disease, stroke, and type 2 diabetes. A person may be diagnosed with metabolic syndrome if they have at least three risk factors, such as excess belly fat, high blood pressure, high blood sugar, high triglycerides, or low HDL (“good”) cholesterol.
Today, about 2 in 5 adults in the United States meet the criteria for metabolic syndrome, making it a major public health concern.
The Therapeutic Lifestyle Changes (TLC) program was created by the National Heart, Lung, and Blood Institute to help improve heart and metabolic health. The program focuses on three main areas:

Regular exercise is another key part of TLC. Experts recommend at least 30 minutes of moderate exercise, such as brisk walking or cycling, on most days of the week.
TLC also encourages maintaining a healthy weight through balanced eating and regular physical activity.

Compared to the control group, people following TLC showed improvements in:
Researchers also found that participants in the TLC group were nearly four times more likely to recover from metabolic syndrome.
Metabolic syndrome is common, but research shows that practical lifestyle changes can meaningfully improve health. Healthier eating, regular physical activity, weight management, and reducing sedentary behavior may help lower the risk of long-term cardiometabolic disease and improve overall well-being.
