The past surgeon general has estimated that close to what percent of our most dreaded diseases could be prevented with lifestyle changes such as diet and exercise?

The assertion that close to 85% of our most dreaded diseases could be prevented through lifestyle changes such as diet and exercise underscores the significant impact that healthy lifestyle choices have on overall health and disease prevention. This percentage reflects research indicating that many chronic diseases, such as heart disease, diabetes, and certain types of cancer, are largely influenced by lifestyle factors. By adopting healthier eating habits, engaging in regular physical activity, and avoiding harmful behaviors such as smoking, individuals can greatly reduce their risk of developing these diseases.

The statistic highlights the importance of prevention through lifestyle modifications, which can lead to improved health outcomes and lower healthcare costs. While it's acknowledged that not all diseases are preventable due to genetic, environmental, or other uncontrollable factors, the emphasis on lifestyle choices illustrates a proactive approach to health management. This knowledge is crucial for personal trainers and health professionals in educating clients about the benefits of making positive changes to their daily routines.
