Macronutrient Protocol

Meaning

A macronutrient protocol is a precisely defined, structured dietary plan that specifies the target ratio or absolute amounts of carbohydrates, proteins, and fats an individual should consume daily for therapeutic purposes. This structured nutritional approach is often utilized in clinical nutrition to achieve specific metabolic or body composition goals, such as targeted weight loss, lean muscle accretion, or the management of insulin resistance. Protocols are typically highly individualized based on a patient’s basal metabolic rate, current activity level, and underlying hormonal and genetic profile. Consistent, meticulous adherence to a well-designed protocol is essential for therapeutic efficacy and sustained physiological adaptation.
