Whole30
Whole30 is a 30-day elimination diet designed to reset your relationship with food. For 30 days, you eliminate sugar, alcohol, grains, legumes, dairy, and processed additives. After day 30, you systematically reintroduce groups to identify food sensitivities.
It's not designed for long-term adherence — the 30-day frame is the point.
