Fuel Score, what the number means

Fuel Score is a single 0 to 100 number that gives clients a daily "did I fuel today" read. It sits in the ring on the Today card.

How it is calculated

The formula has two parts:

- Protein hit (60 percent of the score). Today's protein divided by the target, capped at 100 percent. Hitting target scores the full 60. - Calorie range (40 percent of the score). Full 40 if total calories sit within 10 percent of target either way. The contribution falls off the further the client drifts. 20 percent over or under gives 60 of the 40. 50 percent off gives 0.

Both inputs use the active nutrition plan's targets for the day (training day or rest day if your plan splits them).

Bands

- 80 or above. On track. Ring fills primary colour. - 60 to 79. Getting there. Ring amber. - Below 60. Needs work. Ring rose (softer than red because overshooting and undershooting both happen and neither is a failure). - No score yet. Empty ring with a dash. Shown when there is no plan, or when there are no logs for today.

The "Over target" caption

When any macro is more than 10 percent over target, the ring shows an "OVER TARGET" caption in amber under the score. This matters because the score formula caps protein hit at 100 percent. Being well over on calories or fats can pull the score down without it being obvious why. The caption and the "+30g" chips on the macro bars together tell the client which direction the score moved from.

Why protein is weighted highest

Research on dietary adherence consistently shows hitting protein is the single highest-leverage nutrition behaviour for body composition and recovery. Carbs and fats are flexible inside the calorie budget. The score reflects that. Clients who hit protein and stay in the calorie band score 90 or above even when individual macros vary day to day.

What the score is NOT

- Not a verdict. A score of 60 is not a failure, it is data. - Not a fitness metric. It tells you about today's intake, not training quality or weight trajectory. - Not aligned with the dominant macro picker. Whether a client features Protein, Carbs, Fats, or Calories on their Today card, the Fuel Score formula is unchanged. A future version may weight the score against the client's chosen macro. For now it is protein-first.

Phase 1 limitation

The score uses target adherence only. Not photo confidence, not micronutrient coverage, not meal timing relative to training. A later phase may add a training-aware bonus for clients who hit their protein on workout days. For now: hit protein, stay in the calorie band, score 80 or above.
