Why Insulin Resistance Creates a Vicious Cycle of Fat Gain | Dr. Robert Lustig
Levels Advisor Robert Lustig, MD, describes how insulin drives fat gain.
Understanding insulin resistance:
– Insulin is a hormone, and it’s a growth factor.
– It makes cells grow and divide.
– It is helpful when you’re a growing child, are in puberty, or are pregnant.
– We are more insulin resistant at these times to support growth.
– However, insulin also drives fat growth.
– Insulin is released in response to a rise in glucose (blood sugar) after a meal.
– It tells our cells to let glucose in for energy.
– If we consume too much of the foods that drive insulin release (i.e., sugar and refined carbohydrates), insulin resistance will result.
– Insulin resistance occurs when cells can’t handle the glucose load and stop responding to insulin’s signaling.
– Ultimately, insulin drives fat gain, and fat leads to more insulin resistance.
– Fat loss will not occur unless there’s a reduction in insulin release.
– You can reduce insulin release by keeping blood sugar more stable.
