What to Expect in Phase 3: Increase Time in Range

Time in Range (TIR) is the percentage of how long your glucose value was within your target range over a 24-hour period. In Phase 3 of the Level2 Method, you will be learning how to increase your TIR.

Foods and activities on a curvy glucose line that is gradually flattening.

The Goal for this Phase:

Avoid glucose peaks most of the time to improve time in range
to 70% or higher
(for minimum of 14 days).

(And please check with your provider to make sure a 70% time in range is right for you. It isn’t appropriate for all people.)
