The orb is your glycogen tank. Eating fills it; moving or fasting drains it. A single meal is a small share of the tank, so the level rises a notch rather than emptying — it only visibly drains over hours of deficit. That's the physics working, not a bug.
Reserve learns your real metabolism over time. Until you've logged a few days and weighed in, the number is your goal distance as an honest starting point. Log meals and add weigh-ins and it calibrates to you — that's the whole idea.
