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 — 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:
• Burn stored fat for energy
• Improve insulin sensitivity
• Support cellular repair and regeneration
• 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:
• 12:12 – A gentle starting point, ideal for beginners
• 18:6 – Popular for belly fat loss and metabolic improvement
• OMAD (One Meal a Day) – Best suited for experienced fasters
• 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.
