Gezond Leven Diëtisten

What Gezond Leven Diëtisten does

Gezond Leven Diëtisten is a privately held dietitian practice founded in 1999 by Berdien van Wezel and headquartered in Den Haag, Netherlands. The company delivers professional dietetics services spanning weight management, low-carbohydrate nutrition, medical nutrition therapy (diabetes, cholesterol, gut disorders, pregnancy), mindful eating training, and specialized support for patients using GLP-1 agonists such as Ozempic and Mounjaro. It operates two physical locations in Den Haag — a flagship practice and retail store on Van Hoytemastraat and a consultation-only site inside the DOC general practitioners health center at Boomsluiterskade — and extends its reach nationally through online consultations via Zoom and Teams, home visits, and an e-commerce webshop.

The business model combines fee-for-service dietetics consultations with product retail. Revenue is generated from individual intake (€117.50) and follow-up (€37.50) consultations, strippenkaarten packages of 5 (€185) or 10 (€350) sessions, workshops, and product sales spanning the PS. Food & Lifestyle weight loss program (rebranded from PowerSlim in 2021), the PS. Life low-carb staple food line, Prodimed meal replacements, PURE The Winery sugar-free wines, and resold third-party supplements from Orthica and Orthiflor. Dutch basic health insurance reimburses up to 4 consultations per year, providing partial demand support.

The practice is bootstrapped and founder-owned, with no external funding or parent company identified. Its competitive positioning rests on the founder's 25+ years of experience, a team of qualified dietitians registered in the Dutch paramedical quality register, multi-channel distribution, and an integrated product ecosystem that complements clinical services. Customer acquisition is driven by content marketing (blog, SEO), social media (Facebook and Instagram), referrals from general practitioners, and workshop-based community engagement, primarily targeting individual consumers in the Den Haag region and online nationwide.

Direct peers

• Noom: Digital weight-management platform pairing users with coaching for behavior change and nutrition. Directly comparable to Gezond Leven Diëtisten on the dietitian-led coaching model, though delivered at much larger scale digitally.
• The 1:1 Diet (formerly Cambridge Weight Plan): Meal-replacement weight-loss program combined with one-to-one consultant coaching. Highly comparable to Gezond Leven Diëtisten's PS. Food & Lifestyle offering of low-carb meal replacements paired with dietitian guidance.
• PS International (PS. Food & Lifestyle): The program brand whose products and protocols Gezond Leven Diëtisten delivers. As the parent program operator, PS International sits one level above Gezond Leven Diëtisten in the same low-carb coaching-plus-meal-replacement value chain.

Broad incumbents

• Weight Watchers (WW International): Large incumbent weight-management brand offering coaching, community, and food products globally. Operates in the same weight-management and nutrition-coaching space but at vastly larger scale and broader product portfolio.
• SlimFast: Established meal-replacement diet brand. Comparable to the Prodimed and PS. Food & Lifestyle product lines that Gezond Leven Diëtisten distributes and sells through its webshop.
• Jenny Craig: Weight-management program combining personalized coaching with meal products. Directly comparable service-plus-product model to Gezond Leven Diëtisten's integrated consultations and retail product offerings.

Emerging players

• Lifesum: Digital nutrition-tracking app with meal plans and health insights. Comparable to the online consultation and self-tracking aspects of Gezond Leven Diëtisten's offering, but delivered as a consumer app rather than in-person dietitian practice.

Others

• Prodimed: Manufacturer of carbohydrate-low meal-replacement products distributed by Gezond Leven Diëtisten. A product supplier and ecosystem partner rather than a direct competitor, with overlapping product categories to PS. Food & Lifestyle.
