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 many calories are in a pound of body fat?

A pound of body fat contains approximately 3,500 calories. Pure fat has about 9 kcal per gram, but adipose tissue is roughly 87% fat with some water and protein, giving it an energy density of about 3,436–3,752 kcal per pound.

Is the 3,500 calorie rule accurate for weight loss?

It is a rough approximation, not a precise predictor. Research published in the International Journal of Obesity found the rule overestimates actual weight loss because it ignores metabolic adaptation — your body burns fewer calories as you lose weight, shrinking the effective deficit over time.

How many calories do I need to burn to lose 1 pound?

A cumulative deficit of roughly 3,000–3,500 calories is needed to lose one pound of body fat. However, early weight loss also involves glycogen and water, which cost far fewer calories per pound, so scale weight drops faster at first and slower later.

How much weight can I lose in a week on a 500-calorie deficit?

Clinical studies show people typically lose about 0.5–0.7 lbs per week initially on a 500-calorie deficit, with the rate slowing as metabolism adapts. The NIH Body Weight Planner uses a dynamic model for more accurate predictions than the simple 3,500-calorie rule.

Is it harder to lose a pound of fat or a pound of muscle?

Harder to lose fat. A pound of fat stores about 3,500 calories, while a pound of muscle contains only roughly 800 calories. This means your body can catabolize lean mass much more easily than fat during a calorie deficit — which is why high protein intake and resistance training are critical to preserve muscle while dieting.

How Many Calories in a Pound of Body Weight? The Truth

How many calories in a pound? The 3,500-calorie rule is a starting point — but modern science reveals why it overestimates your actual weight loss.
