As a general rule of thumb, we recommend taking a breath test before eating and again approximately one hour after you eat.
We recommend testing regularly throughout the day, at hourly intervals (for example one hour, two hours and three hours after eating).
We recommend a maximum of 10 breath tests in 24 hours for the longevity of your FoodMarble device.
In general, any breath tests are better than none, so don’t worry if you don’t get your timing exactly right. You might still see interesting results up to four hours after eating, so keep up your logging!
Breath test reminders: The FoodMarble app allows you to set hourly breath test reminders which are prompted as soon as you log a meal. Recent Meal reminders should appear on your phone one hour after the time of the logged meal.
