From Generic Diets to Personalized Keto Meal Plans
Ketolific turns a 1-minute quiz into a fully personalized weekly keto meal plan. We built the quiz-to-plan engine, dietary profile calculator, meal swap system, and shopping list generator — serving 21,000+ paying customers with a one-time purchase model.
The Problem
Most keto diet products hand you the same 7-day plan regardless of whether you're a 25-year-old athlete or a 50-year-old with a desk job. They ignore what foods you actually eat, what your body needs, and what your goals are.
The result: users drop off within days. The plan doesn't feel like theirs. They can't swap meals they dislike, can't figure out what to buy at the store, and have zero insight into their own dietary profile.
Generic keto plans ignored individual body metrics, food preferences, and health goals. Users got cookie-cutter PDFs that didn't match their lifestyle.
Stuck with meals you didn't like? Too bad. Existing plans offered no flexibility to replace a dish while staying within your macro targets.
Users had to manually figure out what ingredients to buy, how much, and for which meals. No aggregated shopping list from the plan.
Users had no idea what their BMI, metabolic age, or daily calorie target actually was. They started a diet blind, with no personal health context.
What Was at Stake
Personalization Engine from 8 Input Dimensions
Gender, health goal, activity level, exercise frequency, meat preferences, vegetable preferences, dairy preferences, and body measurements all feed into a single algorithm that generates a nutritionally balanced 7-day plan. Every combination must produce a valid result.
Meal Swap Without Breaking Nutrition
When a user swaps a lunch, the replacement must match the original meal's calorie and macro profile while respecting their ingredient preferences. The swap algorithm filters from hundreds of keto recipes in real time.
Conversion-Optimized Purchase Funnel
The quiz-to-paywall flow had to feel seamless — not salesy. Urgency mechanics, social proof from 21,000+ reviews, dual payment gateways (Stripe and PayPal), and instant post-payment access all needed to work without friction.

Feature Spotlight
Dietary Profile Dashboard
After the quiz, users see their BMI on a curve chart, metabolic age, daily calorie target with a gauge meter, recommended water intake, achievable weight, and a macro donut chart (75% fats, 20% protein, 5% carbs). It makes the plan feel personal before they see a single recipe.
Conversion-Optimized Onboarding
The 8-step quiz uses full-screen questions with a progress bar, hexagonal icon buttons, and toggle ingredient selectors. Each step collects data that makes the generated plan more personal — so by the time users hit the paywall, they're invested in their result.
Smart Shopping List
The shopping list aggregates every ingredient from the weekly plan, deduplicates quantities, and tracks what's been purchased with checkbox strikethroughs. Users know exactly what to buy and how much — no mental math at the grocery store.
