INSIGHT

What 'Microdose' Means

Noom defines microdose as roughly 2%–25% of a high maintenance GLP‑1 dose.
That range equates to about 0.05 mg up to ~0.6 mg of semaglutide versus 2.4 mg maintenance.

ANECDOTE

Geoff's Personal Microdose Results

Geoff Cook personally microdosed semaglutide and saw his A1C drop from 5.6 to 5.3.
He lost 10 pounds, increased daily activity, and found habit stacking easier while microdosing.

ADVICE

Combine GLP‑1 With Daily Behavior Work

Noom bundles behavior change with medication and charges $99 first month then $199 monthly.
Use daily micro-habits (steps, protein targets, resistance training) to entrench habits while on microdose.
