>>11327484Eating healthy and physical activity can prevent and even cure many diseases, including cancer. But it definitely doesn't always work. Some types of cancer thrive on glucose, and eating keto or fasting can work. But some cancers thrive on fatty acids (or maybe even ketones). Some people have a severe genetic defect, for which diet/exercise have little impact. Besides diet and physical activity, I think stress is the most important contributor to disease. If everyone ate healthy, had plenty of physical activity, and low chronic stress, I think pretty much no one would be obese or have type 2 diabetes. And there would be less people with autism, epilepsy, (bipolar) depression, schizophrenia, ADD, MS, dementia, and cancer. But all of them would still occur, just at lower rates.
