Your profile is the foundation of your personalized nutrition experience. SmartEat AI uses your profile information to calculate your daily calorie and macro targets, then generates customized meal plans that match your goals and preferences.
What You’ll Need
Before creating your profile, gather the following information:
- Personal measurements: Height (cm) and weight (kg)
- Birth date: Must be between 16 and 100 years old
- Body type: Lean, normal, stocky, or obese
- Gender: Male or female
- Activity level: Low, medium, or high
- Fitness goal: Lose weight, maintain weight, or gain weight
- Meal preferences: Number of meals per day (1-6)
- Dietary preferences: Food tastes, restrictions, and diet types
All measurements should be current and accurate to ensure the best meal plan recommendations.
Creating Your Profile
Provide your personal measurements and demographics:
Height: Between 140-220 cm
Weight: Between 35-300 kg
Birth Date: You must be at least 16 years old
Gender: Male or female
Body Type: Select the option that best describes your current physique
Be honest about your body type. SmartEat AI uses this to estimate your body fat percentage and calculate accurate macro targets.
Choose your fitness objective:
Lose Weight: The system will set calories at 80% of your TDEE (Total Daily Energy Expenditure) with higher protein to preserve muscle mass
Maintain Weight: Calories match your TDEE for weight stability
Gain Weight: Calories are set at 110% of TDEE plus 150 kcal to support muscle growth
Select your typical daily activity:
Low (1.2x): Sedentary lifestyle, little to no exercise
Medium (1.55x): Moderate exercise 3-5 days per week
High (1.725x): Intense exercise 6-7 days per week
Be realistic about your activity level. Overestimating can lead to excessive calorie targets that hinder your goals.
Choose how many meals you want per day (1-6):
3 meals: Traditional breakfast, lunch, and dinner
4 meals: Adds one snack between main meals
5 meals: Adds two snacks throughout the day
6 meals: Maximum frequency for consistent energy and metabolism
The system automatically distributes your daily calories across your chosen number of meals.
Select ingredients and cuisines you enjoy. The AI will prioritize recipes featuring these preferences.
Specify any allergies, intolerances, or foods you avoid:
Allergies (nuts, shellfish, dairy, etc.)
Religious or ethical restrictions
Personal dislikes
The AI uses advanced filtering to ensure all recommended recipes comply with your restrictions.
Choose dietary styles that align with your goals:
High Protein: Emphasizes protein-rich foods
Low Carb: Reduces carbohydrate intake
Vegan: Plant-based, no animal products
Vegetarian: No meat, may include dairy and eggs
Low Calorie: Focuses on lower-calorie options
High Fiber: Prioritizes fiber-rich foods
High Carb: Emphasizes carbohydrate sources
You can select multiple diet types that work together.
Review Calculated Targets
After submitting your profile, SmartEat AI automatically calculates:
Daily Calorie Target: Based on your BMR (Basal Metabolic Rate) using the Mifflin-St Jeor equation
Protein Target: Adjusted based on your lean body mass and goals (2.0-2.2g per kg of lean mass)
Fat Target: Set at 25% of total calories
Carbohydrate Target: Fills remaining calories after protein and fat
Body Fat Percentage: Estimated from gender and body type
What Happens Next
Once your profile is saved:
- Macro calculations complete: Your personalized nutrition targets are stored
- Recipe database filtered: The system identifies compatible recipes based on your preferences and restrictions
- Ready for meal planning: You can now generate your first weekly meal plan
You can update your profile anytime as your goals, measurements, or preferences change. The system will recalculate your targets automatically.
API Endpoint
For developers, the profile is managed via:
This endpoint supports both creating new profiles and updating existing ones (upsert operation).
Tips for Success
- Update regularly: Recalculate targets as you lose or gain weight
- Be specific with restrictions: The more detailed your restrictions, the better the AI can filter recipes
- Start conservative: Begin with fewer meals per day if you’re new to structured eating
- Choose realistic goals: Sustainable progress is better than aggressive targets
- Adjust activity level seasonally: Your activity may change throughout the year
