Nutrition planning in Fuel turns a set of targets into decisions you can execute, using Apple Watch energy context and your recent trend to keep the plan aligned with reality.

Planning units

Fuel planning is built around a small set of units that stay stable across goals.

Energy targets answer how much you can spend today. Macro targets answer how you want that energy to be distributed. Micronutrient targets answer whether the plan is nutritionally dense enough to sustain performance and adherence.

A day example

Planning works when targets survive the day you actually have.

On a high activity day, the watch fed target may rise because active energy is higher. Protein can stay stable as an anchor, then carbohydrate becomes the variable that makes training days easier to execute without drifting into low energy availability. On a low activity day, the target may fall, carbohydrate can tighten, and fat becomes the place where portion drift quietly breaks the plan.

Micronutrient targets do not change the energy math, but they do change food choice. They push the plan toward food density so hunger and recovery do not degrade as you execute the macro plan.

Setting targets without guessing

Targets are only useful when they are testable. That means you can log the inputs and check the outcome.

For most users the fastest path to stable targets is a tight loop: wear Apple Watch, log food, record weigh ins, then let coaching and reviews reflect the consequences of those inputs.

If your targets feel disconnected from what you are seeing on the scale or in training, use Personalized Metrics and Energy Balance to diagnose whether the issue is missing data, inconsistent logging, or a target that needs to move.

Use Adjusting Macronutrients when you want to override calories or macros immediately without running a new plan flow.

Meal structure that survives real days

A plan that depends on perfect days fails. Build meals around repeatable anchors and vary only the parts that change your day to day.

Protein is the easiest anchor because it stabilizes satiety and recovery. Carbohydrate is the easiest lever because it can scale with training volume and daily activity. Fat is the easiest place to hide excess energy, so it should be the slowest variable to drift.

Planning with recipes and repeats

If you eat the same meals often, treat them as assets. Logging gets easier, and your week becomes easier to analyze because variance drops.

When you try a new recipe, log it once with care and then reuse it as a template. The goal is not a single perfect entry. The goal is repeatable entries that keep week over week comparisons meaningful.

Connecting planning to coaching

Daily and weekly reviews are where planning becomes feedback.

If you want the plan to improve, use coaching to ask for adjustments that are grounded in constraints such as training schedule, hunger, and time, then verify the change by watching what happens to adherence and trend over the next one to two weeks.
