Business Challenge

IWL had expanded its services into professional healthcare channels, however its consumer-led brand did not signal the clinical credibility and professional support behind the service. A brand refresh was needed to differentiate IWL from fast-results, app-led weight loss programs and position IWL as a trusted brand for professional healthcare partners and prospective patients.

Brand Solution

A core insight we found was that people did not need another promise of fast transformation. They needed a credible, supported method they could believe in after years of dieting attempts to keep weight off. We built IWL’s visual identity in mind with its core strengths and audience: credible, qualified support and a sustainable approach to weight loss – without throwing away what made the brand trusted to begin with.

Visual Identity

The interval icon and core blue-teal foundation was kept for familiarity. The identity focused on improving areas creating the greatest perception gap: typography authority with a new serif font, replacing stock imagery, and clearer hierarchy, spacing and colour usage to signal safe, institutional, and professional.

Digital Rollout

We established distinct type systems for editorial contexts (email, web campaigns) and product contexts (mobile, web app), each optimised for its own reading environment while remaining under one visual identity to ensure consistency across the full customer journey.
