See the moment your body switches to burning fat
Every calorie app tells you what you ate. Fuel Shift shows you what your body may be doing with it right now. See your energy across blood glucose, liver glycogen, muscle glycogen, and body fat, then watch your fuel stores rise, fall, and shift in real time. Log food and workouts normally. Fuel Shift simulates what happens next, shows what fuel mix you’re using, and lets you preview how a meal could change your timeline before you eat it.
Fuel Shift is a web app that tracks real-time changes in your body's energy sources, including blood glucose and body fat, based on your food intake and workouts. It allows users to simulate the effects of meals on their fuel mix and energy levels.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
