GLYCEMIC CORRELATION

Post-Lunch Brain Fog & Slump

High glycemic index meals trigger rapid insulin release, leading to reactive hypoglycemia 60โ€“90 minutes later. Your brain lacks steady glucose, resulting in heavy eyelids and sluggish concentration.

Frequently Asked Questions

Is Burn a calorie tracker?
No. Burn is an experiment engine. Rather than making you weigh every gram of food forever, Burn helps you test a focused habit (like No Added Sugar or Dairy-Free) and records your energy, mood, sleep, and digestion to see if it actually helped you.
Do I need to follow a specific diet?
Not at all. Start with a guided experiment or define your own simple habit (like eating dinner earlier or drinking water first). Burn organizes your observations; it does not force a rigid meal plan.
Is Burn free?
Yes! Your first experiment in Burn is 100% free with full access to daily check-ins and AI-assisted result reports on the App Store and Google Play.
Does Burn give medical diagnoses?
No. Burn provides informational, observational wellness self-tracking. It computes mathematical correlations from your self-reported logs and does not provide medical diagnoses or replace healthcare advice.

Your Routine Is Personal.
Your Observations Can Be Too.
