Net calories

Net calories is intake minus calories burned. Cookrange does not use this model: burned calories are shown on top of your target, and the target itself does not move.

Net calories is the number you are left with at the end of the day: intake minus calories burned. Eat 2,400 kcal, burn 400, and your net is 2,000. Most calorie trackers work this way and usually present it like this: exercise, and the day’s calorie target rises, so you can eat back what you “earned”.

Two problems with the model

The first is measurement. Calories burned is a far less certain number than calories eaten. You can read a meal’s calories off a label or a database with reasonable accuracy; you cannot read what a 45-minute session actually burned. Wearables’ exercise-expenditure estimates carry a known margin of error. The net-calorie model subtracts one number from another, and one of them is markedly less reliable than the other, so the error passes straight into the target.

Two problems with the model, continued

The second is behavioural. A target that rises with exercise turns exercise into a mechanism for earning budget. That can work against you: it licenses eating more in the short term, and over time it reduces exercise from an end to a means.

What Cookrange does instead

Cookrange does not use the net-calorie model. Calories burned are shown live on top of the day’s target, but the target itself does not change. With a 2,180 kcal target and 230 kcal burned, the screen reads 2,410 - but that does not mean your target became 2,410. The target moves only when you regenerate the plan.

The distinction is subtle and it decides the outcome. Under a net-calorie model the day’s target drifts continuously, which makes it harder to know what you are actually progressing against. In Cookrange the target holds steady through the day and burned calories sit above it as additional information - context, not an input that rewrites the goal.

This is a trade-off, not a perfect answer

The design has a cost and it should be said: for someone training at very high volume, a fixed target can understate real expenditure. The right move there is to regenerate the plan - to update the target deliberately and on the record - rather than waiting for it to drift. For people who prefer automatic adjustment, tools like MacroFactor do it with a different model; the comparison is on Cookrange and MacroFactor.

One limit matters today too: Cookrange has no wearable and no Apple Health or Google Fit integration. Burned-calorie information does not arrive automatically from a watch. Which means the net-calorie debate is, for Cookrange right now, partly theoretical.
