Tag: 40 30 30 macro

Developed by Dr. Barry Sears as part of the Zone Diet, the 40 30 30 macro breakdown allocates 40% of daily calories to carbohydrates, 30% to protein, and 30% to fat. This moderate, balanced approach is designed to stabilize blood sugar, manage insulin levels, and support consistent energy throughout the day.

Diet trends and rules often have their names misremembered, and the search for **what is the 30 30 40 diet rule?** is a prime example. This query most often refers to the 40/30/30 macro split, a structured eating plan that emphasizes a balanced intake of carbohydrates, protein, and fat to help regulate insulin and support overall health.
