Insulin: An Undeserved Bad Reputation

Is insulin really the root cause of fat gain? Or has the carbohydrate-insulin model of obesity been oversold?
In this episode, Dr. Layne Norton breaks down what insulin actually does in the body, why short-term biochemistry snapshots don’t tell the whole story, and what the highest-quality human evidence really shows about low-carb vs. low-fat diets when calories and protein are controlled.
We cover metabolic ward trials, meta-analyses of controlled feeding studies, overfeeding research, and why GLP-1 drugs (which increase meal insulin) produce massive fat loss. Spoiler: insulin is not a wizard that can violate thermodynamics.
