AI Coaching

Updated February 6, 2026

This content is for informational purposes only and is not a substitute for professional advice.

AI coaching in Fuel translates your actual log history into guidance you can execute, with daily and weekly reviews as checkpoints rather than motivational noise.

What coaching is grounded in

Fuel coaching is only as good as the inputs it can audit. The core inputs are food logging, Apple Watch energy and workouts, and weigh ins that produce a usable trend.

If those inputs are stable, coaching can explain outcomes in a way that stays tied to evidence. If those inputs are missing, coaching can still propose a plan, but it has less to verify against.

What coaching produces

Fuel coaching has two outputs, each designed to be checked against your log.

Daily review answers what happened today, why it happened, and what tomorrow should look like. Weekly review answers what happened this week, what should change next week, and what constraints to watch.

If you want targets to move, ask for a specific change and the constraint driving it. Then check the result against adherence and trend over the next one to two weeks.

Getting better answers from Coach Chat

Coach Chat is most useful when you provide constraints, not just goals.

Name your training schedule, your time window for meal prep, and any dietary constraints. Point to a concrete pattern you saw in Timeline or in reviews. That makes it possible for coaching to propose a plan that can be checked against the next week of data.

Example prompts

Use Coach Chat as a planning editor, not a search box.

Bad

What should I do to lose fat

Better

Over the last 14 days my weight trend is flat. My average intake is about ____ kcal with ____ g protein. I train ____ days per week.

Propose updated calorie and macro targets that fit my schedule of ____ and tell me what signal would make you adjust them again.

Correcting coaching when the data is wrong

If a meal was logged incorrectly, fix the log first and then run the review again. Coaching should be downstream of the corrected record, not an attempt to reason around a known error.
