Dietary and Lifestyle Changes refer to modifications in an individual's eating habits, food choices, and overall way of living. These changes can include adopting a healthier diet with more fruits, vegetables, whole grains, lean protein sources, and healthy fats while reducing the intake of processed foods, sugary items, saturated fat, trans fat, sodium, and excessive alcohol consumption. Lifestyle changes may include regular physical activity or exercise, stress management techniques such as meditation, yoga, deep breathing exercises, getting enough sleep, reducing sedentary behaviors like sitting for prolonged periods of time, and avoiding smoking or exposure to secondhand smoke. These combined modifications can help prevent chronic diseases, improve overall health, and enhance the quality of life.
