Fasting sounds like deprivation—fake fasting sounds like effectiveness in everyday life: eating and activating the fasting metabolism. How does that help at work? Greater mental clarity (ketosis/BDNF), better stress regulation, and a noticeable energy boost, even without a “hardcore regimen.” We talk to Nancy Rizos about evidence and practice: how teams get started together, how the cafeteria and home office play a role, what good communication achieves (clarifying “why,” ensuring voluntariness), and which simple routines create acceptance—from breakfast jars to quick check-ins. With concrete examples from companies and clear indications of who it is particularly suitable for.
