What Is the Whole30 Diet

The program excludes sugar, alcohol, grains, legumes, soy, dairy, and additives, focusing on whole foods such as meat, seafood, eggs, vegetables, fruit, and natural fats. Participants follow a strict list of approved and banned ingredients, track meals, and avoid weighing themselves during the 30-day window. The official program is documented on the Whole30 website and detailed in the book "It Starts With Food," which outlines the physiological and psychological rationale behind the rules whole30.com.
