Explanation:

Karen's best way of maintaining a healthy life is through healthy eating, rich in nutrients and practicing physical activities regularly.

Adequate and healthy food is understood to mean eating practices appropriate to the biological and socio-cultural aspects of individuals, as well as to the sustainable use of the environment. That is, it must be in accordance with the nutritional needs of each stage of the course of life and with the special dietary needs; accessible from a physical and financial point of view; harmonic in quantity and quality; based on adequate and sustainable productive practices; free of physical, chemical, biological and genetically modified organisms.

Physical activity is defined as any body movement, produced by skeletal muscles, which results in energy expenditure greater than resting levels. For the maintenance of health and quality of life, the ideal is that every citizen performs at least 30 minutes of physical activity, 5 days a week of moderate intensity, continuously or accumulated, divided into sessions of 10 or 15 minutes.
