Mastering Your Metabolism

Ketosis and Intermittent Fasting are two of the most powerful tools for metabolic optimization. By shifting your body's primary fuel source from glucose to ketones, you unlock stable energy, mental clarity, and efficient fat oxidation. Our suite of tools is designed to take the guesswork out of this transition.

The Keto Foundation

Success on Keto requires precision. Use the Macro Calculator to set your targets, and the Net Carb Tool to ensure you stay under your limit. Most people find that staying below 20-30g of net carbs is the 'magic number' for sustained ketosis.

The Fasting Shield

Fasting isn't just about weight loss; it's about cellular repair (autophagy). Use the Visualizer to sync your eating windows and the GKI Calculator to measure the depth of your metabolic state during extended fasts.

Developer's Note on Sustainability

The best diet is the one you can stick to. Don't feel pressured to start with Extreme 23:1 fasts or < 1.0 GKI scores. Start with a simple 16:8 window and focus on high-quality whole foods. As your body becomes fat-adapted, the longer windows will happen naturally.
