The Garmin stress score is calculated based on Heart Rate Variability (HRV), a metric that reflects the balance of your autonomic nervous system, the body's control center for involuntary functions. It's a common observation for users to see this score spike after eating, which is a normal physiological response to the demands of digestion.

According to Garmin's official support, while consuming healthy food is always a good idea, it does not directly impact the Body Battery metric. However, this simple answer overlooks the complex, indirect ways that your nutrition can dramatically influence the key physiological factors that do control your Body Battery: stress and sleep.
