The link between your rhythm, weight, and appetite.

Morning

Cortisol peaks after waking, shaping your energy levels and appetite signals as your day begins.

Evening

It should drop before bedtime, cueing your body to wind down. When it stays elevated, you may notice it's harder to manage your appetite and cravings.

What your full curve shows

Your rhythm connects the dots between your cortisol levels and how you experience energy, appetite, and weight changes.

The tests showed what my doctor told me! He said my cortisol levels were mostly running low, I am eating less and not losing weight. The blood tests did not show it, but the Eli salivary cortisol tests showed it is normally low. The next thing is to find an endocrinologist who uses them.

Knowing how my cortisol levels have been spiking at night has helped me adjust my lifestyle and make changes to drop my levels at night (like they should be) and help me loose the weight I've been battling to loose.

5.0

With chronic illness, some doctors I have found are very dismissive because it not a 'lab test', that's not the point of Eli, its tremendously helpful identifying trends. It has helped me tweak my habits to improve sleep and energy tremendously.
