Michi’s Ladder consists of five tiers of food, with tier 1 considered the highest tier and tier 5 considered the lowest. The foods in tier 5 include items high in calories and fat, or low in nutrients. As you climb towards tier 1, you’ll find low-calorie, low-fat foods that contain high amounts of vital nutrients. Michi’s diet followers should focus on foods from tiers 1 and 2, and avoid foods from the other tiers as much as possible.
