🔬 Scientific Methodology

This page describes the technical, scientific, and methodological criteria used in the development of the digital tools and informational content available on this site. The goal is to ensure transparency regarding the origin of the calculations, the limitations of the indicators presented, and how the results are generated.

✓ Based on international scientific standards

🎯 Purpose of the Tools

The available calculators were developed for educational and informational purposes, allowing users to understand body indicators widely used in population studies and public health materials, such as the Body Mass Index (BMI), basal metabolic rate, and estimates related to physical well-being.

⚠️ Important Notice

The tools do not perform medical diagnosis and do not replace evaluation by health professionals.

📚 Scientific Basis

The calculations presented are based on internationally recognized formulas used in scientific research, health agencies, and educational materials, including:

Body Mass Index (BMI) — proposed by Adolphe Quetelet
Body weight classifications used by the World Health Organization (WHO)
Metabolic equations widely used for energy estimation
Population parameters adopted in epidemiological studies

The classifications and references used in the tools also follow guidelines widely adopted by international public health organizations, such as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). These institutions use the Body Mass Index as one of the population indicators for nutritional assessment and health trend monitoring across different countries.

The classifications used on this site follow technical references widely adopted in the scientific literature and in public health policies. Among the main sources are documents published by the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), which use the Body Mass Index (BMI) as an epidemiological indicator for assessing the nutritional status of adult populations.

These organizations publish guides and technical reports used globally by researchers, health professionals, and academic institutions for the analysis of body weight, obesity, and associated metabolic risks. The tools on this site reproduce only the mathematical calculations from these references, for educational and informational purposes.

The recommendations and classifications presented on this site are based on technical documents, scientific publications, and educational materials produced by these organizations, ensuring that the parameters used are aligned with international research and public health standards.

🧮 How the Calculations Work

The tools perform automated mathematical operations based on the data entered by the user. For example, the BMI calculation uses the following formula:

BMI = weight (kg) ÷ height² (m)

After the calculation, the result is compared against standardized classification tables, allowing an educational interpretation of the obtained indicator to be displayed.

💻 Technological Implementation

The algorithms used were developed to faithfully reproduce the original formulas described in technical literature. The implementation prioritizes:

🎯

Mathematical Accuracy

We ensure that all calculations faithfully reproduce established scientific formulas.

⚡

Fast Processing

Calculations performed instantly in the user's browser, with no server required.

🔍

Transparency

Clear and documented operating logic to ensure reliability.

🔄

Continuous Updates

Periodic review of the tools to maintain compliance with updated standards.

👨‍💻 Technical Responsibility: Technical responsibility for the development and logical validation of the digital tools can be consulted on the Technical Officer page.

⚠️ Limitations of the Indicators

Indicators such as BMI are statistical tools used for population analyses and have important limitations, including:

They do not differentiate between muscle mass and body fat
They do not take into account individual body composition
They do not replace professional clinical assessment
They should be interpreted only as an initial reference

🏥 Medical Recommendation

For this reason, it is recommended that any health-related decision be made with appropriate professional guidance.

🔄 Updates and Revisions

The methodology adopted is reviewed periodically to ensure alignment with publicly available technical references and best practices for developing informational digital tools.

We maintain our commitment to technical excellence and the reliability of the information presented, conducting regular audits of our algorithms and procedures.

🌟 Transparency and Commitment

The site maintains a commitment to clarity in the information presented, seeking to offer accessible, technically structured content based on verifiable criteria.
