The Misconception of the 3500 Calorie Rule

The podcast debunks the widely believed 3500 calorie rule for weight loss, explaining that it oversimplifies the process. Changes in calorie intake impact calorie expenditure, leading to metabolic adaptations that slow down weight loss. The example of a 30-year-old woman cutting 500 calories daily only resulting in a 32-pound loss over a year, instead of the predicted 52 pounds, highlights this flaw. The rule fails to consider the body's adjustments to weight loss, resulting in exaggerated weight loss predictions.
