30-Day Challenge

Clean Eating Tier Chart

Use this chart to score the overall quality of your food choices for the day. Build most meals around S Tier foods, use A Tier foods strategically, and keep F Tier foods limited.

Judge the day by the overall pattern of your meals and snacks — not by one isolated food. A day can still be strong if most choices stayed in S tier and A-tier foods were used with intention.
