Whole30 is a 30-day dietary program designed to help individuals reset their eating habits and identify food sensitivities. Participants eliminate sugar, grains, dairy, legumes, and processed foods from their diet, focusing instead on whole, unprocessed foods like vegetables, fruits, meat, seafood, and healthy fats. The program encourages mindful eating and promotes a better understanding of how certain foods affect the body. After the 30 days, participants gradually reintroduce eliminated foods to observe any reactions, helping them make informed choices about their long-term diet.
