Belly Fast – Burn Fat Smarter Transform your health with intermittent fasting. Belly Fast is a simple, easy-to-use fasting tracker designed to help you lose weight, reduce belly fat, and improve metabolic health without complicated setups. No email sign-up or credit card required to start. The Problem We Solve Modern eating patterns β€” frequent meals, late-night snacking, and constant digestion keep insulin levels high and make it difficult for the body to burn stored fat. Over time, this can lead to weight gain, insulin resistance, low energy, and stubborn belly fat. Intermittent fasting gives your body time to rest, reset, and switch into fat-burning mode. Belly Fast makes this process clear, structured, and easy to follow. What Is Intermittent Fasting? Intermittent fasting focuses on when you eat. By cycling between fasting and eating windows, your body can: β€’ Burn stored fat for energy β€’ Improve insulin sensitivity β€’ Support cellular repair and regeneration β€’ Increase mental clarity and energy Belly Fast helps you stay consistent and understand what’s happening in your body at each stage of the fast. Fasting Plans Tailored to You During onboarding, Belly Fast uses your inputs and calculate your BMI to recommend a fasting plan suited to your body. You can always adjust your plan as you progress. Choose from flexible fasting methods: β€’ 12:12 – A gentle starting point, ideal for beginners β€’ 18:6 – Popular for belly fat loss and metabolic improvement β€’ OMAD (One Meal a Day) – Best suited for experienced fasters β€’ 48-Hour Fast – An advanced option that should be approached carefully and is recommended only for experienced fasters Start simple and progress at your own pace.

Smart Hydration & Notifications Stay consistent and hydrated: β€’ Hydration reminders during fasting β€’ Eating window start alerts β€’ Fasting completion notifications for multi-day fasts β€’ Custom notification timing β€’ Works in the background Daily Insights & Education Learn something new every day and stay motivated: β€’ Daily AI-generated fasting insights β€’ Clear explanations of each fasting type (12:12, 18:6, OMAD, 48-hour) β€’ Simple, science-based guidance on what happens during a fast β€’ Education on why belly fat (visceral fat) is dangerous and how fasting can help Low-Calorie Meal Recipes Fasting-friendly meal ideas for your eating window: β€’ Low-calorie recipes β€’ Nutrition-focused meal suggestions Progress, Privacy & Control Built with simplicity and privacy in mind: β€’ Use the app without an account β€’ Optional cloud backup and device sync β€’ Secure sign-in options when you choose β€’ No data selling or tracking β€’ Delete your account and data at any time if you backup Designed for Simplicity Unlike other fasting apps where features feel scattered and overwhelming, Belly Fast keeps everything easy to understand and focused on what matters β€” helping you fast consistently and burn fat smarter.
