Key Takeaways

Read in 30 seconds

1
Glucose is Fuel
2
Insulin Spike: Taking carbohydrates at once causes blood sugar to spike, release large amounts of insulin, and plummet in reaction (Glucose Spike). This 'fluctuation' is the cause of intense afternoon drowsiness and sluggishness.
3
Ultrahuman M1: Service to analyze data sent from sensor (Abbott Libre) attached to arm with dedicated app. Visualize 'What happens if I eat this donut' with a score.
4
Food Logging: Just taking a picture of what you ate, AI analyzes and links with blood glucose fluctuations. Individual differences like 'I am strong against white rice but weak against pasta' are revealed.
5
Walking after Meals: Walking for just 15 minutes after meals dramatically suppresses spikes. When you see this in data, you can't help but walk.

Introduction: Dashboard of the Body

No one drives on the highway without looking at the car’s fuel gauge. However, we work without knowing the state of our body’s fuel (glucose).

“Feeling tired somehow”, “Head is not working”. 90% of the true identity of that sensory disorder is blood glucose fluctuation. By visualizing this, meals change from “Pleasure” to “Strategy”.

1. The Sensor: FreeStyle Libre 3

Medical sensor from Abbott. Attach a coin-sized chip to your upper arm. Needle pierces only for a moment (Pain is almost zero). This monitors your blood data for 24 hours for 2 weeks.

2. The Analytics: Ultrahuman M1

The sensor itself only outputs raw numbers. Ultrahuman tells the meaning (Insight). (*App service linked with sensor)

“Your metabolic score is 85. Oatmeal for breakfast was correct.” “Alert: Rapid increase detected. Please squat right now.”

Just like an F1 pit crew, it gives instructions in real time.

3. Comparison: Knowing Individual Differences

項目	High Spike Foods	Stable Foods
Udon / Pasta	Spike (Max Drowsiness)	Whole Wheat is better
Fruit	Juice is dangerous	Whole fruit is OK
Eating Order	From Carbohydrates	From Veggies/Meat
Countermeasure	Sleep	Walk

4. The Data-Driven Diet

General diet books are useless. Because even if it says “Bananas are good”, it might not fit your constitution.

By wearing a CGM (Continuous Glucose Monitor), you can find the “Correct Answer” only for your body. That is knowledge for a lifetime. It is worth trying even for just 2 weeks. Know how your body reacts to specific ingredients.
