At Progressivfit, the accuracy of your health data and the safety of your fitness journey are our top priorities. All health-related calculations, nutritional recommendations, and goal settings within the app are derived from globally recognized scientific formulas and medical guidelines.
Below you will find the detailed methodology and sources for the calculations used in your personalized fitness profile.
The BMI is a widely used screening tool to identify weight categories that may lead to health problems.
Calculation: BMI= Wheight (kg)/ [Height (m)]^2
Scientific Source: World Health Organization (WHO) BMI Classification.
Reference: WHO Global Health Observatory - BMI
To determine your daily calorie needs, we first calculate your BMR (Basal Metabolic Rate), which is the number of calories your body needs to function while at rest.
Calculation: Mifflin-St Jeor Equation
Male: (10*weight)+(6.25*height)-(5*age)+5
Female: (10*weight) + (6.25*height) - (5*age) - 161
Scientific Source: Mifflin MD, St Jeor ST, et al. "A new predictive equation for resting energy expenditure in healthy individuals."

Your Total Daily Energy Expenditure (TDEE) is calculated by multiplying your BMR by an activity factor (PAL) based on your training frequency.
Activity Factors used: 1.375 (Light), 1.55 (Moderate), 1.725 (Very Active).
Scientific Source: Food and Agriculture Organization of the United Nations (FAO) - Human energy requirements.
Reference: FAO - PAL Methodology
Protein recommendations are adjusted based on your specific fitness goals (e.g., muscle gain vs. general fitness).
Guidelines: 1.4g to 2.0g of protein per kg of body weight.
