Last month my husband and I started a 30-day diet plan called the Whole30. The basic idea is to “reboot” your system by excluding foods from your diet that you might be intolerant of without knowing it. You stick to a simplified, clean diet and let your body cleanse itself. After 30 days, you gradually reintroduce foods and note any reactions. Whole30 is a fairly extreme diet, since it restricts, sugar, alcohol, grains, legumes, fast food, and dairy. You are forbidden to stand on a scale.
