How CalFast Tracks Your Meals, Nutrition, Goals, and Progress

Here's how CalFast tracks meals, calculates goals, and helps users stay consistent.

Personalized Calorie Goals Built on Science

CalFast begins by calculating your Basal Metabolic Rate (BMR) — the calories your body burns at rest. This uses the widely accepted Mifflin-St Jeor equation, considered one of the most accurate methods for estimating resting energy needs.

Your BMR is then adjusted using your activity level to estimate Total Daily Energy Expenditure (TDEE) — the total calories you burn in a day.

From there, CalFast sets calorie targets based on your goal:

• Weight loss
• Maintenance
• Muscle gain

Safe minimum calorie thresholds are applied to ensure sustainability and health.

Smart Macronutrient Distribution

Once calories are set, CalFast calculates macronutrients with purpose:

• Protein is prioritized based on body weight and goal, supporting muscle retention and recovery
• Fat is allocated as a percentage of total calories to maintain hormonal health
• Carbohydrates fill the remaining calories to fuel energy and performance

Minimum thresholds for fats and carbs ensure the body receives essential nutrients even during calorie deficits.

AI-Powered Meal Tracking

CalFast simplifies food logging using AI-driven analysis:

• Scan or upload food images
• Detect individual food items and ingredients
• Estimate calories and macros at the ingredient level
• Allow users to review, edit, add, or remove ingredients

This keeps users in control while benefiting from AI efficiency.

Barcode and Nutrition Label Scanning

For packaged foods, CalFast supports:

• Barcode scanning
• Nutrition label recognition
• Automatic macro extraction

This removes manual entry and improves accuracy when consuming store-bought foods.

Net Calories and Activity-Based Adjustments

CalFast tracks net calories, which accounts for:

• Calories consumed
• Calories burned through activity

When connected to health platforms, CalFast can optionally adjust daily goals based on real activity levels rather than static estimates — making targets more realistic on active days.

Health Score: Daily Feedback That Matters

Beyond numbers, CalFast provides a Health Score — a daily score out of 100 that reflects how well you stayed aligned with your goals.

The score evaluates:

• Calorie balance
• Protein intake
• Carb and fat balance
• Sugar and sodium levels
• Fiber intake

Rather than punishing users, the Health Score highlights areas for improvement and rewards balanced days with positive reinforcement.

Streaks, Groups, and Motivation

Consistency is the foundation of results.

CalFast tracks:

• Daily logging streaks
• Progress milestones
• Group participation and leaderboards

These features turn habit-building into a motivating experience rather than a chore.

Insights That Help You Improve

CalFast's AI-driven insights analyze trends over time:

• Frequent overeating or undereating patterns
• Macro imbalances
• Consistency trends
• Behavior-driven suggestions

This allows users to adjust habits proactively rather than reactively.

Built for Real Life

CalFast doesn't expect perfection. It's designed to:

• Adapt to real-world eating
• Adjust goals intelligently
• Provide clarity without overwhelm
• Encourage consistency over extremes
