In Waste No More, veteran strategist Claudio B. Landsberg challenges one of the most deeply ingrained beliefs in retail and food service: that profit depends primarily on selling more. Instead, this groundbreaking book reveals how the fastest path to profitability isn’t about revenue growth — it’s about eliminating waste. 
 
Drawing on real-world experience and industry data from the 2010s, Landsberg shows how seemingly “unavoidable” losses — from inventory shrinkage and food waste to operational inefficiency and employee turnover — silently erode margins. And in a business where net profits often hover at just 3–5%, reducing these losses can be up to 20x more powerful than increasing sales.
 
Through a practical, step-by-step roadmap, this book explores how to: 
 
✅ Identify and quantify the hidden drains on profit in your operations. 
✅ Use pre-2018 technology — POS systems, demand forecasting, IoT sensors, workforce platforms — to gain real-time visibility and control. 
✅ Redesign processes with lean principles to boost efficiency and consistency. 
✅ Implement unit-level management to track waste where it really happens. 
✅ Transform your workforce from a liability into a competitive advantage. 
 
With case studies, diagnostic frameworks, and actionable tools, Waste No More is more than a guide — it’s a playbook for transforming operational losses into sustainable growth. Whether you run a single location or a global chain, this book will change the way you think about profit, revealing why what you save is far more powerful than what you sell.
