How Platika calculates nutrition goals.

Last updated: June 2026

Our Approach

At Platika, we believe nutrition tracking should be transparent.

The calorie and protein targets shown in the app are estimates based on established scientific equations and nutrition guidelines. They are designed to help you better understand your eating habits and support your nutrition goals.

Platika is intended for informational and educational purposes only and should not be considered medical advice.

Protein Target Calculation

Protein requirements vary depending on age, body weight, activity level, and personal goals.

Platika estimates your daily protein target using:

  • Age
  • Sex
  • Height
  • Weight
  • Activity level
  • Selected nutrition goal

Different nutrition goals require different protein intake ranges. For example, individuals aiming to build muscle or lose weight may benefit from higher protein intake than those simply maintaining their weight.

Our recommendations are based on evidence from internationally recognized organizations and peer-reviewed research.

Daily Calorie Estimation

Platika estimates daily calorie needs using the Mifflin–St Jeor equation, one of the most widely accepted predictive equations for resting energy expenditure in healthy adults.

Estimated resting energy expenditure is then adjusted using Total Daily Energy Expenditure (TDEE) based on the user's selected activity level.

Depending on the selected goal, Platika estimates calorie targets for:

  • Maintaining weight
  • Moderate weight loss
  • Building muscle
  • Increasing protein intake while maintaining energy balance

To help avoid unrealistically low calorie recommendations, Platika applies a minimum calorie threshold when appropriate. This safeguard is intended to support practical nutrition planning and should not replace individualized medical or dietary advice.

AI Food Analysis

Platika uses artificial intelligence to estimate the nutritional content of meals from food photographs.

Nutrition estimates are generated using image recognition together with publicly available food composition data.

Estimated values may vary depending on:

  • Portion size
  • Preparation method
  • Hidden ingredients
  • Food presentation
  • Image quality
  • Lighting conditions

For this reason, all nutrition values shown in Platika should be considered estimates rather than exact laboratory measurements.

Medical Disclaimer

Platika is not a medical device.

The app does not diagnose, treat, cure, or prevent any disease.

Nutrition estimates, calorie targets, protein recommendations, and AI-generated insights are intended for informational purposes only and should not replace professional medical or dietary advice.

If you have a medical condition, diabetes, kidney disease, are pregnant or breastfeeding, follow a prescribed diet, or require individualized nutrition advice, please consult a qualified healthcare professional before making dietary changes.

Continuous Improvement

Nutrition science continues to evolve.

Platika regularly reviews scientific literature and nutrition guidelines and may update its calculation methods as new high-quality evidence becomes available.
