Validate whether your meal plan actually matches your targets.

The meal plan validator checks your current meal setup against calorie and macro objectives so you can spot mismatches before they compound.

  • Audit meal plans for calorie and macro alignment.
  • Identify uneven protein distribution or poor target matching.
  • Use validation before committing to a weekly eating plan.
