Robert Lustig: Why the Little Women of Loja Prove Obesity Isn’t Always the Root of Chronic Disease
Robert Lustig describes a founder-effect growth hormone receptor mutation in women from Loja, Ecuador, who have Laron dwarfism: they are short, obese, have high growth hormone (GH) and low IGF-1, yet — despite persistent obesity over decades — showed no cancer or diabetes compared with higher rates in their relatives. He uses this example to argue that obesity is not always the root cause of chronic disease.
