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.

How much of a calorie deficit do I need to lose weight?

A deficit of 300 to 500 calories per day is safe and effective for most people, producing roughly 0.5 to 1 pound of weight loss per week. Larger deficits of 500 to 1,000 calories per day can produce up to 2 pounds per week but require higher protein intake and resistance training to minimize muscle loss.

Is a 500-calorie deficit safe?

Yes, for most healthy adults. A 500-calorie daily deficit is the most widely recommended amount by health organizations including the NIH. It is sustainable, preserves muscle mass, and minimizes the risk of nutrient deficiency compared to more aggressive cuts.

What is the minimum calories I should eat to lose weight?

Most guidelines recommend a minimum of 1,200 calories per day for women and 1,500 for men. Eating below these thresholds risks nutrient deficiencies, muscle loss, and severe metabolic adaptation that makes long-term weight loss harder.

How do I know if I am in a calorie deficit?

If your weekly average body weight is declining consistently (0.3–1 kg per week), you are in a deficit. If the scale has not moved in 3–4 weeks, run a strict tracking audit — research shows most people underreport their calorie intake by up to 47 percent.

Can I be in a calorie deficit and still not lose weight?

Short-term, yes — water retention and glycogen changes can mask fat loss for 1–2 weeks. Long-term stalls (4+ weeks) usually signal that the true deficit has shrunk due to metabolic adaptation, inaccurate tracking, or a subconscious drop in daily movement.
