Your measured burn

Standard calorie calculators guess from age, height, and weight. Two people with identical stats can burn hundreds of calories apart, so a guess can put your targets in the wrong place from day one.

FuelPath stops guessing once it has your data: it measures what your body actually does.

The math is energy balance. If you eat 2,400 calories a day and your weight trend is dead flat, you burn about 2,400. Losing half a pound a week on the same intake means you burn about 250 more than you eat.

FuelPath runs this over a rolling 28-day window using your logged food and weigh-ins. Wearable calorie estimates are deliberately not used; your scale and your log beat a wrist guess.

The engine needs honest logging and regular weigh-ins: it uses days with credible intake and needs enough weigh-ins spread across the window. Until then it shows warming up with progress bars.

Daily weigh-ins are ideal (first thing, after the bathroom, before food). Imperfect logging days are automatically excluded, so one rough weekend does not poison the number.

Tap the Expenditure card for the full breakdown: the exact inputs, the trend, and what the number means for each phase.

Each phase has an anchor off your measured burn. Fuel holds at it. A Build adds a surplus sized for about half a pound a week. A Cut takes a deficit, and once you have body composition on file that deficit is sized against your own fat stores rather than a flat percentage, which is sharper at both ends of the range.

Your expenditure breakdown shows the whole picture: your fat mass, the daily ceiling that comes off it, and how much of that your current setting spends. The ceiling is what your body can release in a day, never a target to chase, and your coach picks how much of it to use.

Adjustments apply in steps capped at 250 calories, so no plan ever lurches. If your targets and your anchor drift apart, your coach sees it and decides. Ask the assistant to explain your numbers any time.
