How to Use Lifesum in 2026: Step-by-Step Guide
Lifesum is an AI-powered nutrition and meal planning app used by 60 million people worldwide. It tracks food, generates personalized meal plans, and provides nutritional guidance aligned with your health goals — whether you're losing weight, building muscle, or simply eating more intentionally.
Lifesum is one of the most widely used nutrition apps globally — 60 million users across 200 countries — combining detailed food tracking, AI meal planning, and science-backed dietary plans in a beautifully designed app.
AI-Personalized Meal Plans
Lifesum's core differentiation: AI meal plans that adapt to your goals, dietary preferences, and lifestyle. Tell the app your goal (lose weight, maintain, build muscle, improve energy), your dietary pattern (Mediterranean, vegetarian, keto, balanced), and activity level. The AI generates weekly meal plans with exact meals, portion sizes, and macros for each day.
Plans are dynamic: swap meals you don't like, mark items you've already eaten, and the AI adjusts. The plan is a suggestion, not a rigid prescription.
Comprehensive Food Tracking
Lifesum's database covers 200,000+ foods, including barcodes for packaged products, restaurant menu items, and international cuisine. Log meals by searching, scanning a barcode, or photographing your plate (AI estimates calories from photos). Track calories, macros, vitamins, and minerals.
Dietary Plans with Science Backing
Lifesum offers 20+ dietary plans validated by dietitians and nutritional scientists: Mediterranean, 5:2 intermittent fasting, keto, anti-inflammatory, Scandinavian, Nordic, and more. Each plan has clear principles, food guides, and educational content explaining the science.
Health Score
Lifesum's "Health Score" rates the nutritional quality of your food choices on a scale of 1–10, based on the Life Score algorithm co-developed with registered dietitians. It rewards variety, whole foods, and balanced macros — not just calorie restriction.
Integration with Health Data
Lifesum syncs with Apple Health, Google Fit, Fitbit, Garmin, and other fitness trackers. Activity data adjusts your daily calorie budget automatically — if you ran 5km, your budget increases proportionally.
Pricing
Lifesum Free: basic food tracking and logging. Lifesum Premium: $34.99/year or $8.99/month (all meal plans, personalized guidance, detailed nutrition data, Health Score, recipe suggestions). Available on iOS and Android.

Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show Lifesum what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
