Hypothalamic obesity: Insulin, weight loss breakthrough

  • In 1995, at St. Jude Children's Research Hospital, children who survived brain tumors became massively obese, known as hypothalamic obesity.
  • Despite previous attempts with diet and exercise, these children couldn't lose weight due to a slowed metabolism, even gaining weight on 500 calories a day.
  • The discovery of leptin in 1994 led to the hypothesis of leptin resistance in these children due to damage to their hypothalamus.
  • Administering a drug called octreotide, which suppresses insulin release, led to weight loss and increased activity in these children.
  • A double-blind placebo control trial confirmed that lowering insulin levels not only aided weight loss but also improved activity levels.
  • The traditional view of weight gain being a result of overeating and lack of exercise was challenged by the findings, showing high insulin levels as the primary cause.
  • In 2006, the focus shifted from weight loss to reducing insulin levels in a clinic, leading to successful weight loss.
  • Fructose was identified as a key driver of type 2 diabetes and fatty liver disease, similar to alcohol in metabolism.
  • The sugar industry's manipulation in the 1960s to shift blame from sugar to saturated fat was uncovered, revealing a deliberate misinformation campaign.
  • The book "Metabolic Sugar and Alcohol" delves into the deception orchestrated by the sugar industry, exposing the truth behind the health impacts of sugar consumption.
