Behind the scenes
How Our AI Builds Your Plan
No black boxes. Here's exactly how your personalised meal plan is created — the science, the technology, and the principles we follow.
Our Approach
What makes YourMealPlan different from other meal plan services?
Every plan is generated from scratch. There are no pre-built templates, no recycled PDFs, and no one-size-fits-all approach. When you fill in the form, your answers are processed in real time to produce a plan that is entirely unique to you — your goals, your preferences, your lifestyle.
Is this based on real nutritional science?
Yes. Your calorie targets are calculated using the Mifflin-St Jeor equation — one of the most widely accepted methods for estimating basal metabolic rate. We then apply an activity multiplier based on your exercise habits to determine your Total Daily Energy Expenditure (TDEE). From there, calories are adjusted up or down depending on whether your goal is fat loss, muscle gain, or maintenance.
The Technology
How does the AI actually work?
We use multiple specifically trained AI models that work together to build your plan. The first stage collects and validates your inputs — goals, preferences, foods you want to avoid, budget and time constraints. The second stage calculates your nutritional targets using established formulae. The third stage generates your meals, cross-referencing outputs between models to ensure accuracy, variety, and nutritional balance. Nothing is guessed.
What do you mean by "cross-referencing between models"?
Rather than relying on a single AI output, your plan is checked against multiple models to catch errors, flag nutritional imbalances, and verify that macro totals align with your calculated targets. Think of it as a built-in review process — one model builds, another checks.
How does it know what meals to suggest?
The AI considers everything you tell it: foods you love, foods you hate, how much time you want to spend cooking, whether you're on a budget, and your overall goal. It doesn't just pick meals at random — it constructs each day to hit your macro and calorie targets while respecting every preference you've set.
The Science
What is the Mifflin-St Jeor equation?
It's a formula used to estimate your Basal Metabolic Rate (BMR) — the number of calories your body burns at rest. It takes into account your age, weight, height, and sex. Published in 1990, it's considered one of the most accurate predictive equations for BMR and is widely used by dietitians and nutritionists.
How are my calorie targets calculated?
Your BMR is calculated using Mifflin-St Jeor, then multiplied by an activity factor based on how active you are (sedentary, lightly active, moderately active, very active). This gives your TDEE — the total calories you burn in a day. If your goal is fat loss, we create a controlled deficit. If it's muscle gain, we add a surplus. For maintenance, we match your TDEE.
How are macros split across meals?
Once your daily calorie target is set, it's divided into protein, carbohydrates, and fats based on your goal. Each meal is then built to contribute proportionally to those daily totals, so you're not front-loading or back-loading nutrients — it's balanced across the full day.
Transparency
Is this a replacement for a dietitian or nutritionist?
No. YourMealPlan is designed for general healthy eating and fitness goals. It's a tool to help you eat better, not a substitute for professional medical or dietary advice. If you have a medical condition that requires a specific diet, please consult a healthcare professional.
Can the AI get things wrong?
AI is powerful but not infallible. That's exactly why we use multiple models to cross-reference every plan. The nutritional calculations are based on established science, and the meal generation is validated against your targets before delivery. If something doesn't look right, we want to know — your feedback helps us improve.
What happens to my data?
The personal information you provide is used solely to generate your plan. Payments are processed securely by Stripe — we never see or store your card details. Your data is not shared with third parties and is not used to train AI models.
