Glucose spikes may be hindering your weight loss progress,

[ and it’s not always because of the foods you think. ]

Plain sourdough toast raises glucose about +43 mg/dL for Signos members. Pick three toppings and see if you can bring it under a +30 spike.

Plain sourdough toast
Average rise+43 mg/dL

Choose your toppings

0 of 3 chosen
Plain sourdough toast: +43 mg/dL
That’s the average rise Signos members see from a slice of sourdough. In the Atlas, what you put on the bread matters more than the bread.

Glycemic rise is illustrative, based on data from 19,351 sourdough meals in the Signos Food Atlas, but everyone’s response is different, which is why Signos measures yours.

Know what your body signals are telling you.

Signos pairs a 15-day glucose biosensor with an app that shows how food, movement, sleep and stress affect you, as it happens. Clear guidance, no guesswork.

Stelo glucose biosensor

Illustration, shown enlarged.

A hair-thin filament does most of the work. Signos does the rest.

No finger pricks. The Stelo biosensor rests a soft, flexible filament just under the skin of your arm, where it reads your glucose around the clock.

  1. 1
    One click to apply
    The applicator places the filament and its needle pulls right back out. Only the soft filament stays.
  2. 2
    Hair-thin and flexible
    About 5.7 mm long, roughly the length of a grain of rice. It bends with you as you move.
  3. 3
    A tip that reads glucose
    The tip is coated with an enzyme that reacts with glucose in the fluid around your cells, creating a tiny electrical signal.
  4. 4
    Straight to your phone
    The sensor turns that signal into a glucose reading and sends it to the Signos app over Bluetooth.

How Essentials works: a sensor, worn when it counts.

On a GLP-1, the medication leads, so you don’t need a sensor every day. You wear one at the moments that matter, then act on what it shows. In between, the app keeps tracking your doses, your weekly progress and your body composition.

    Check that your progress is muscle-sparing, not just a lighter scale.
