A plan built around you, not the average.

Whether you're cutting, bulking, managing a condition, or just eating cleaner — we analyze your goals and assemble meals that actually fit your week.

What we analyze

Four signals shape every recommendation — so your plan reflects how you actually live.

Your goals

Fat loss, muscle gain, performance, or maintenance — we calibrate calories and macros to match.

Your body & activity

Weight, height, training load, and lifestyle inform daily targets that move with you.

Dietary needs

Allergies, intolerances, religious preferences, vegetarian, pescatarian, low-FODMAP — all respected.

Taste & history

What you loved, skipped, or rated poorly trains the model so next week is even better.

How we put your week together

Every plan is assembled with three layers of logic — nutrition first, variety second, joy always.

01

Match macros to your goal

We translate your goal into daily protein, carb, and fat targets — then build meal combinations that hit them across the week, not just per plate.

02

Filter for what's off-limits

Allergens, ingredients you dislike, or meals you've already had recently are removed before we even start ranking options.

03

Optimize for variety & joy

We rotate proteins, cuisines, and textures, and weight in your past ratings — so you never get stir-fry four nights running.

Built for every kind of eater

No matter your starting point, there's a plan shape that fits.

Fat loss & lean cutting
Muscle gain & high-protein
Endurance & performance
Diabetes-friendly & low glycemic
Heart-healthy & low sodium
Gluten-free & celiac-safe
Dairy-free & lactose intolerant
Vegetarian & pescatarian
Postpartum & family-friendly

Your plan gets smarter every week

Rate a meal, swap one out, or update your goal — the next delivery reflects it. You're always one tap away from a plan that still fits.

Personalization FAQ

How your plan is built.
