Part 2/10:
Lustig highlights a staggering fact: 93% of Americans exhibit some level of metabolic dysfunction, with only 7% being metabolically healthy. He attributes this largely to insulin resistance and points out that many are unaware of their condition partly because fasting insulin tests are often not conducted. This situation is compounded by guidelines from organizations like the American Diabetes Association, which discourage the testing of fasting insulin. Dr. Lustig contends that these recommendations are misguided due to a misunderstanding of insulin’s relevance to metabolic health.
