how it works
Ember Philosophy
Every goal weight
is a mountain.
Ember shows the trail.
Forget meal plans and complicated macros. Ember tracks one thing: the calorie distance between where you are and where you want to be.
The Mountain

Roughly the number of calories stored in one kilogram of body fat. Every calorie deficit chips away at the mountain.
