How it works

Three steps.
That's genuinely it.

We cut out every piece of friction between you and eating well. No food databases, no barcode scanning, no meal logging.

02
Get your targets

Fuel calculates your exact daily calories and macros using proven science — the same method dietitians use.

03
Follow your plan

Get a full week of meal days, or let AI generate something completely personalized to your taste and dietary preferences.

What's inside

Everything you need.
Nothing you don't.

Precision calorie calculator

Mifflin-St Jeor BMR with activity and goal adjustments. The same method used by registered dietitians — not a rough estimate.

AI meal generator

Tell it your dietary preferences — vegan, keto, gluten-free, halal — and get a full personalized day of eating in seconds. Every generation is unique.

Weekly meal planner

See your entire week at a glance. Weekends get a built-in flex allowance so you can stay on track without feeling restricted.

Fiber & micronutrient targets

Calories and macros are just the start. Fuel also shows your daily targets for fiber, water, iron, vitamin D, omega-3, and more.

5 goals, not 2

Aggressive cut, cut, maintain, lean bulk, or bulk. Each with scientifically optimized macro ratios — not one-size-fits-all percentages.

Zero food logging

No scanning barcodes. No weighing chicken. Just follow the plan. Built for people who want results without becoming obsessed with food tracking.

Early feedback

People are already eating better.

★★★★★

"I've tried MyFitnessPal three times and always quit. This is the first thing that actually told me what to eat instead of just tracking what I already ate."

Marcus T. Lost 14 lbs in 10 weeks
★★★★★

"The AI meal generator is ridiculous. I said I was vegan and it gave me a full day of meals I actually wanted to eat. Took 10 seconds."

Priya S. Maintaining goal weight
★★★★★

"I'm a busy dad of three. I don't have time to think about food. This thing just tells me exactly what to eat. That's all I needed."

Common questions

Everything you
wanted to ask.

Is this actually free? +
Yes — the calorie calculator, macro targets, and sample meal plans are completely free. No credit card, no account needed. The only paid feature is unlimited AI meal generation, which is $7.99/month.
How is this different from MyFitnessPal? +
MyFitnessPal is a food diary — you log everything you eat after the fact. Fuel tells you what to eat before you eat it. No barcode scanning, no obsessive tracking, no guilt. Just a simple plan to follow.
Do I have to log my food every day? +
Never. That's the whole point. Fuel gives you a plan — you follow it. No logging, no weighing chicken, no tracking every bite. Most people quit food logging within 2 weeks. Fuel is built so you don't have to.
How accurate is the calorie calculator? +
We use the Mifflin-St Jeor equation — the gold standard used by registered dietitians. It's accurate within about 5% for most people. We recommend recalculating every 4–6 weeks as your weight changes.
Is it safe? Will I lose muscle? +
Yes, it's safe. When you're in a calorie deficit, Fuel automatically raises your protein target to 35%+ of calories specifically to protect lean muscle. This is standard practice in sports nutrition. If you have a medical condition, always check with your doctor first.
What if I'm vegetarian, vegan, or have dietary restrictions? +
Fuel supports 10 dietary preferences including vegetarian, vegan, pescatarian, keto, paleo, gluten-free, dairy-free, halal, and kosher. The AI meal generator tailors every meal day to your preference.
How does the AI meal generator work? +
It uses Claude AI to generate a completely personalized day of eating — breakfast, snacks, lunch, and dinner — built around your exact calorie and macro targets. Every generation is unique. Free users get one try, Pro users get unlimited.
Can I cancel anytime? +
Yes, absolutely. Cancel from your account settings at any time and you won't be charged again. No questions asked, no hoops to jump through.
