What a Test Day Looks Like
You’ll Do It Twice (Day 1 and Day 2)
Your Morning
Fast 8+ hours (water only)
Only water for 8+ hours before testing. Your FreeStyle Libre must be active for 24+ hours and synced to the Tastermonial app.
Before testing
Check your glucose levels
Before testing, ensure your CGM reads within the ideal fasting range:
70–110 mg/dL (general)
70–130 mg/dL (if managing diabetes)
If your reading is above range, wait 15 minutes and recheck.
During the test
Log your test
Replace your breakfast with one LYFEfuel essential bar. Log the in-app experiment.
After the test
2-hour satiety observation
After consuming the test products, do not eat or drink anything except water for the next 2 hours. This period helps us accurately measure how full you feel and how your body responds. At the 2-hour mark, you’ll be prompted to log your satiety level in the Tastermonial app.

What’s the science behind how LYFEfuel supports glucose balance & curb hunger?
What Makes It Work
High fiber + healthy fat + protein = delayed digestion → stabilized blood sugar → prolonged fullness
AimSlim™ enhances appetite control
Whole-food ingredients offer nutrients without causing glucose crashes
