Musk advocated the use of diet pills to reduce US health care spending. On December 11, local time, Musk posted on social networking platform X: Nothing can improve the health, longevity, and quality of life of Americans like very cheap GLP-1 drugs. He pointed out that most medical expenses occur at the end of life, and obesity is often an important cause of illness, so popularizing GLP-1 drugs can save medical expenses on a long-term scale.
