The app is intended for people beginning a health journey as well as experienced health and fitness coaches. The supplied app description says that Zero supports weight-loss and health-gain habits, preserving muscle, and improving long-term health. It also says that Zero Members have lost millions of pounds and that the app has been featured in GQ, Good Housekeeping, Men’s Health, Fortune, TechCrunch, Women’s Health, The Tim Ferriss Show, The Joe Rogan Experience, and other outlets. ### Fasting timer and fasting types Zero’s timer tracks fasts, progress, and goals. Supported fasting patterns include: - **13-hour fast**, also called a “circadian-rhythm fast,” based on research by Dr. Satchin Panda of the Salk Institute and intended to align the eating window with the body’s internal clock. - **16-hour fast**, or **16:8 intermittent fasting**. - **18-hour fast**, or **18:6**, for more advanced fasters. - **OMAD**, meaning one meal a day. - **20:4 fast.** - **Custom prolonged fasts of up to 7 days.** ### Guidance and habit-building features The supplied description identifies these product areas: - **Fat-Burning Mode:** real-time tips, personalized statistics, daily guidance, and insights into changes the body may experience while fasting. - **Education:** weekly health-research summaries from the Zero science team, translated into actionable steps. - **Motivation:** expert-led and science-backed content, community Challenges, achievements, and other tools intended to maintain focus. - **Rewards:** streaks and Badges that celebrate daily progress and support short-term progress toward longer-term goals. The description says users may begin seeing results in 28 days, including weight loss, better mood, and improved energy, and may see changes by three months in body composition and markers such as waist circumference, fat mass, blood pressure, glucose, and insulin. ## Subscription information Zero is offered through a subscription business model.
