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 is metabolic adaptation?

Metabolic adaptation is the reduction in total daily energy expenditure that occurs during calorie restriction — beyond what changes in body weight alone would predict. It is the body's survival response to a perceived food shortage, involving reduced thermogenesis, lower NEAT, and hormonal shifts that collectively slow your metabolism.

How much does your metabolism slow during dieting?

Research suggests metabolic adaptation typically reduces energy expenditure by 100–400 kcal per day, depending on the severity and duration of the deficit. A 2022 review in the Journal of Strength and Conditioning Research found the magnitude varies widely between individuals, but most people experience some degree of adaptation within the first week of calorie restriction.

Is metabolic adaptation the same as metabolic damage?

No. Metabolic adaptation is a temporary, reversible process — your metabolic rate normalizes when calories are increased back to maintenance. "Metabolic damage" implies permanent harm, which the current evidence does not support. The metabolic slowdown from dieting reverses once food intake increases.

How long does metabolic adaptation last?

Metabolic adaptation reverses relatively quickly once you return to maintenance calories. Research indicates that much of the adaptive component resolves within one to two weeks of ending a calorie deficit, though full hormonal recovery (particularly leptin) may take longer after extended periods of restriction.

Can you prevent metabolic adaptation?

You cannot prevent metabolic adaptation entirely — it is a normal physiological response. However, you can minimize it by avoiding excessively large deficits (keep to 20–25% below TDEE), maintaining adequate protein intake, incorporating resistance training, and using planned diet breaks or refeed days during longer dieting phases.

Metabolic Adaptation: Why Your Body Adapts to Dieting

Metabolic adaptation is your body's survival response to calorie restriction — slowing energy expenditure beyond what weight loss alone predicts. Here's what drives it.
