21-Day challenge | Learn How to Measure and Track from Home

A poorly taken measurement can confuse you more than it helps you.

This challenge teaches you how to ensure every measurement delivers real value. From how to place the blood drop on the glucose meter, to the best time to weigh yourself, or how to take comparison photos of your progress.

Without reliable measurements, there are no reliable decisions.

By the end of this challenge, the user will be able to:

  • Measure glucose, ketones, and body composition correctly.
  • Avoid common errors that distort results.
  • Record symptoms or qualitative data in a structured way.
  • Have useful data for themselves and their specialists.
