The nutrition coaching platform for gyms
Nutrition is your gym's next revenue line.
Most gyms train people hard, then hand nutrition and its revenue to the app store. FuelPath gives your coaches the system to deliver it under your brand, and your first client covers it.
Built inside Black Iron Athletics, Frisco, Texas. Coached, never self-serve.
An athlete looking for coaching? Find a FuelPath gym
Solid Tuesday: protein landed at 178g and you are two days from a 14 day streak. Tonight's easy win is the Greek yogurt you already keep around.
Best streak: 23 days straight. Every one of them taught the engine something about you.
The app store is coaching your members right now
Members download a macro app, fight it alone for three weeks, and quit. The app never knew them and never noticed they left.
Your coaches already answer nutrition questions, in DMs, on the floor, in spreadsheets. Unpaid, unstructured, impossible to scale.
Training plateaus without nutrition behind it, and the coaching revenue goes to online companies your members found on Instagram.
People who train hard deserve a real coach. That should happen at your gym.
Three phases. One path. A coach the whole way.
Your coaches sequence each member's year around their goal: Fuel builds the base, Cut strips fat while holding strength, Build adds muscle. Every phase carries its own targets, and the app measures each member's real daily burn from their own logs and weigh-ins, not a formula.
1. Fuel
Eat at your real burn. Build the base: calories, protein, habits. Holding a new composition happens here too.
2. Cut
Strip body fat while you hold strength. A controlled deficit.
4. Build
Add muscle with a controlled surplus.
The fastest food log in the industry, every way in
Scan a barcode, snap a plate, or photograph a label and AI reads it. Say it out loud. Or search a food list built so 93/7 ground beef and plain eggs come up first. Every way ends on the serving and what is left for the day. The friction that makes members quit other apps is the thing we attacked hardest.
- ✓Barcode, photo, label, voice, and search, one tap from the +
- ✓Standard foods for every ground meat blend, cooked or raw
- ✓Brands, restaurants, and each member's own usual foods ranked first
Every member's daily burn, computed from their own data
Calculators guess. FuelPath measures each member's real expenditure from what they log and what the scale says, then anchors every phase's targets to it. When a metabolism adapts, your coach sees it before the stall.
- ✓Energy-balance engine over the last 28 days
- ✓Per-phase target anchors with guardrails on every change
- ✓Adaptive checks that catch stalls early
A half marathon is not a normal day, and the targets know it
Training syncs from WHOOP and Oura today, with Strava and Apple Health on the way, or gets logged by hand or read off a screenshot. When a session runs above a member's usual training, that day's target grows by the difference, all as carbs, and the rings show the base and the training share separately. Race weeks get carb-load days, race day, and a recovery day on their own.
- ✓Day types set by the training itself: big day, carb load, race, recovery
- ✓Coaches build the training calendar and race-week plans
- ✓A training journal with load, readiness, and records
Your coaches always know who needs them
Check-ins on the cadence each coach sets. A roster that ranks who is dialed and flags who is slipping. AI briefs that hand your coaches the story before they message anyone. Ten clients runs about an hour a week. This is the part no self-serve app can copy.
- ✓Weekly, biweekly, or monthly check-ins, coach's call
- ✓Needs Attention flags silence before it becomes a quit
- ✓Nudges, broadcasts, and a message thread with a human
Goals built on process, phases that end with a highlight reel
Onboarding sets a member's macros and goals in two minutes, process first: the daily wins they control become Habit checkmarks. When a phase ends, their recap plays like a season highlight: days logged, body change, top foods, and the easy wins for what is next.
- ✓Goal sessions at every phase transition
- ✓Wrapped-style recaps when a phase ends
- ✓A Habits list where commitments check themselves off from real data
Outcomes follow the process. Pick up to three daily wins; they go straight into your Habits.
Built by a gym, not a software company
We run Black Iron Athletics in Frisco, Texas. FuelPath exists because our own floor needed it: our coaches run their nutrition clients on it every single day, and every feature on this page was earned there. There is no self-serve tier, because adherence is a relationship, not a feature. The app does the measuring; your coaches do the coaching.
Run nutrition as a real revenue line with unlimited coach seats.
A full toolkit: rosters, briefs, nudges, and the engine behind the numbers.
Join through a provider gym and get coached, not subscribed.
The FuelPath manifesto
A food log is not coaching.
Nobody ever got accountable to a pie chart. The apps got smarter and the outcomes did not.
AI can read your data. It cannot care about you.
We use AI all over FuelPath, and it works for your coach, never instead of one.
Accountability is a person.
Someone who knows your name, sees your week, and expects your check-in. Not a push notification.
Skin in the game matters.
A twenty dollar app is another bill nobody pays attention to. Real coaching costs real money, and that is part of why it works.
The goal is not twelve weeks.
It is a lifelong set of healthy habits and a lifelong healthy relationship with fueling your body: for how you look, how you perform, and how you feel.
So we put a real human coach behind every number. That is the whole product.
