Yes, the BurnBox fast can be done while on a weekly GLP-1 injection, such as semaglutide or tirzepatide, as long as you’re tolerating your medication well and staying hydrated.
In fact, the appetite-reducing effects of GLP-1 medications often make the 3-day fast more manageable. That said, there are a few important considerations:
Monitor for nausea, fatigue, or lightheadedness, especially on your medication’s peak days
Hydration and electrolytes are critical - BurnBox includes an electrolyte booster to help support this
If you’re new to GLP-1 therapy or just starting a higher dose, it’s best to wait until your body adjusts before beginning a fast
Always check with your prescribing provider before starting any fasting protocol to ensure it aligns with your medical plan
