💡 Measurement Tips

  • • Take measurements in the morning before eating
  • • Use a flexible tape measure (tailor's tape)
  • • Keep tape parallel to the floor
  • • Don't pull tape too tight - it should just touch skin
  • • Take 2-3 measurements and use the average
  • • This method is ~3-4% accurate (good for tracking trends)
