Frequently Asked Questions
Yes! All our calculators, the 3-day meal plan generator, and blog content are 100% free. No account needed, no credit card, no hidden fees. We offer optional premium 7-day meal plans for those who want extended planning.
Absolutely. Every single meal in our database is 100% halal. We never include pork, alcohol-based ingredients, or any non-halal items. All recipes are built from scratch with halal compliance as a core requirement.
We use the Mifflin-St Jeor equation, which is considered the most accurate BMR formula for the general population by nutrition researchers. Combined with activity multipliers, it provides a reliable estimate. However, individual metabolism varies — we always show ranges rather than single numbers, and recommend adjusting based on real-world results over 2-3 weeks.
Yes. During the wizard, you can select common allergens to exclude — including dairy, gluten, nuts, soy, eggs, shellfish, and fish. The generator will filter out any meals containing those allergens and substitute appropriate alternatives.
Currently we offer three science-backed diet frameworks: Keto (70% fat, 25% protein, 5% carbs), High Protein (40% protein, 30% carbs, 30% fat), and Low Carb (30% protein, 25% carbs, 45% fat). Each uses the same calorie target calculated from your body stats and goals.
The free plan covers 3 days with full macro breakdowns, grocery lists, and ingredient amounts. For 4-7 day plans with even more variety and meal prep guidance, you can upgrade to our premium bundle directly from the results screen.
