Joice Harada

Joice Harada is a Brazilian nutritionist living in Japan, working to increase health awareness among the Brazilian community in the country. As a certified professional dedicated to promoting better nutrition habits, Joice recognized the need for accessible tools that could help people understand their basic metabolic needs and make informed decisions about their health and diet.

The challenge

Working with the Brazilian community in Japan, Joice identified a significant gap in accessible health education tools. Many of her clients and community members needed a simple way to understand their basal metabolic rate (BMR) and daily caloric expenditure, but existing calculators were either too complex, not available in Portuguese, or lacked the educational context needed to make the information actionable.

Additionally, serving a Portuguese-speaking community in Japan required a solution that could bridge language and cultural barriers while maintaining scientific accuracy.

Abtz Labs' approach

Abtz Labs partnered with Joice to develop a specialized web application focused on basal energy expenditure calculation. The solution was designed to be more than just a calculator—it serves as an educational tool that provides clear, actionable information in Portuguese for the Brazilian community in Japan.

The web application features:

• An intuitive interface for calculating basal metabolic rate based on validated scientific formulas
• Mobile-optimized design for easy access across different devices
• Portuguese language support to serve the Brazilian community effectively

The platform was built with simplicity and accessibility as core principles, ensuring that users could quickly access reliable information without technical barriers or complex navigation.

Results and impact

Since its launch, the basal energy expenditure calculator has become a valuable resource for Joice's nutrition practice and the broader Brazilian community in Japan. The tool provides immediate, scientifically-based information that helps individuals better understand their metabolic needs and make more informed dietary decisions.

The application has enabled Joice to extend her educational reach beyond individual consultations, providing a practical resource that supports her mission of increasing health awareness. The simple, focused design ensures that users can easily access important health information and apply it to their daily routines.

For Abtz Labs, this project demonstrates our commitment to developing technology solutions that serve specific communities and support health education initiatives, regardless of project scale.
