How does the AI recognize food?

Our AI uses advanced computer vision trained on millions of food images. It can identify individual ingredients, portion sizes, and even complex dishes from restaurants worldwide.

Absolutely. Your food photos are processed securely and never shared. We use end-to-end encryption and comply with GDPR and CCPA regulations.

How accurate is the calorie tracking?

Our AI achieves 98% accuracy on standard meals, verified by certified nutritionists. For complex or unusual dishes, accuracy is still above 90%.

Can I use it for specific diets?

Yes! Caloria supports keto, vegan, paleo, Mediterranean, and many other dietary patterns. You can set custom macro targets to match any diet plan.

What's included in Premium?

Premium gives you unlimited meal scans, detailed macro tracking, personalized insights, weekly nutrition reports, priority AI processing, and data export capabilities.

Which devices are supported?

Caloria is available on iOS (iPhone and iPad). Android support is coming soon. Your data syncs seamlessly across all your Apple devices.

What does it mean to be fat adapted?

Being fat adapted means your body has shifted its primary fuel source from glucose to fat. At the cellular level, this involves increased mitochondrial density, upregulated fat-oxidizing enzymes, and greater efficiency at converting fatty acids to ATP — allowing you to burn fat steadily without constant carbohydrate intake.

How long does it take to become fat adapted?

Initial fat adaptation takes 2–4 weeks of consistent carbohydrate restriction. Full cellular adaptation — including mitochondrial changes — takes 4–12 weeks. Elite athletes can show measurable shifts in fat oxidation within 5–6 days, but most people need sustained effort over several weeks.

What is the difference between fat adaptation and ketosis?

Ketosis is a biochemical state defined by elevated blood ketones above 0.5 mmol/L, achievable in 2–4 days. Fat adaptation is a deeper, longer-term metabolic change in how efficiently your cells burn fat. You can be in ketosis without being fat adapted, and fat adapted without always being in active ketosis.

Can you become fat adapted without a ketogenic diet?

Yes. While a ketogenic diet (under 50g carbs/day) is the fastest route, fat adaptation can also develop through consistent low-carb eating combined with regular Zone 2 aerobic exercise and intermittent fasting. The key driver is sustained, repeated depletion of glycogen stores.

Fat-adapted metabolism means your body efficiently burns fat for fuel instead of glucose. Learn what it is, how long it takes, and how to get there.
