Nutrition challenges

Nutrition challenges replace meal-by-meal decisions with one rule that holds for the duration. Whole30 eliminates entire food categories for 30 days so the question stops being what to eat and becomes what's allowed. 75 Soft Challenge pairs a clean diet with 45 minutes of daily exercise and a 1 gallon water target. Intermittent Fasting 16/8 collapses three meal decisions into one eating window. The hardest moment in any nutrition challenge is not the food itself but the social pressure to break the rule for one occasion. Pick based on whether you want to test elimination, timing, or quantity.
