Dr. Robert Lufkin, a physician and father of two young children, has been diagnosed with four chronic diseases the same ones that claimed his father's life. Inspired by his own medical struggles, Lufkin decided to write a book exposing what he calls "medical lies" that contribute to the risk of chronic disease in the US " some of which he says he himself once taught as a professor at UCLA and USC. His own diagnoses, Lufkin said, "woke him up" to the flaws in the medical system. The doctor noted that ... a "new class of diseases" has posed a challenge. These include obesity, diabetes, hypertension, cancer, cardiovascular disease, Alzheimer's disease and even mental illness, Lufkin said. "Up to 80% of our resources are now spent on these chronic diseases." The tools that were so effective in the 20th century " "the pills and surgeries" " might save lives in the moment. But they only address the symptoms of these chronic diseases " not their root causes. "There's a common metabolic cause that underlies most of these diseases," Lufkin said. Ten percent of American adults have type 2 diabetes, and about 38% have prediabetes. The diabetes lie declares that the best way to treat type 2 diabetes is with insulin. However, it will also raise the body's overall insulin levels, worsening insulin resistance, the underlying cause of type 2 diabetes. Additionally, elevated insulin levels drive other chronic diseases. There are also financial incentives. In 2013, sales of insulin and other diabetes drugs reached $23 billion, according to data from IMS Health, a drug market research firm. That was more than the combined revenue of the National Football League, Major League Baseball and the National Basketball Association.
