Crafting Delightful and Sustainable Weight Loss Journeys

Project Overview

As the Product Designer for Pluma, a virtual platform for weight loss, I led the design process over six months, working closely with a cross-functional team that included 1 Product Manager, 1 Engineering Lead, 2 Front-End Engineers, and 2 Back-End Engineers.

Our primary goal was to create an intuitive and delightful application that not only met users' functional needs but also delivered magical moments throughout their journey.

The project achieved significant success, with 35% of users upgrading to premium features, contributing to a 25% increase in company revenue.

Problem Statement

Context

In today's fast-paced world, over 1.9 billion adults are overweight, with 650 million classified as obese according to the World Health Organization (2023). Despite the plethora of weight loss solutions available, individuals struggle to find comprehensive and accessible approaches that address their unique physical, emotional, and psychological needs. Traditional programs often lack integration and personalization, leading to user frustration and high dropout rates.

Pluma was envisioned to revolutionize the weight loss journey by seamlessly integrating dietitians, personal trainers, and psychologists into a single, user-friendly platform. Our mission was to not only facilitate weight loss but to create an emotionally engaging and sustainable path towards holistic well-being.

Problem

Users frequently face fragmented services, juggling multiple apps and appointments, which leads to disengagement and plateauing progress. The absence of personalization, accessibility, and continuous support hampers motivation, making it challenging to achieve long-term success.

Include user stories or quotes.

For instance, Sarah, a 35-year-old marketing manager, shared:

"Coordinating advice from my dietitian, workout plans from my trainer, and managing stress feels overwhelming. I wish there was one place where everything came together seamlessly."

Objective

Our primary goal was to design an intuitive, delightful application that not only meets functional needs but also creates magical moments for users. By focusing on personalization, emotional engagement, and continuous support, Pluma aims to empower users to embrace sustainable lifestyle changes, fostering a deep emotional connection with their health journey.

Research & Discovery

User Research

To deeply understand our users, we conducted a comprehensive mixed-method research approach:

  • In-depth Interviews: Engaged with 20 users through one-hour sessions to explore their motivations, challenges, and emotional experiences with weight loss.

  • Surveys: Distributed online surveys to 150 participants, gathering quantitative data on habits, preferences, and pain points.

  • Diary Studies: Selected 10 participants to document their daily weight loss journey over two weeks, capturing real-time emotions and interactions.

Key Emotional Insights:

  • Desire for Integrated Solutions: 85% of users expressed frustration with managing multiple apps and appointments.

  • Emotional Highs and Lows: Users reported feelings of isolation and discouragement during setbacks, highlighting the need for emotional support.

  • Value of Small Victories: Celebrating minor achievements significantly boosted motivation and adherence to their programs.

Competitive Analysis

We analyzed top competitors like Noom, MyFitnessPal, Fitbit and Wysa:

  • Noom: Offers psychological insights but lacks integration with personal trainers.

  • MyFitnessPal: Strong on tracking but limited in professional guidance.

  • Fitbit: Focuses on activity tracking with minimal dietary or psychological support.

  • Wysa: An AI chatbot providing mental health support but lacking integrated diet and exercise guidance.

Opportunity:

Pluma can fill the gap by offering a truly integrated, personalized, and emotionally supportive platform, setting us apart in the market.
