Common Pitfalls
Translation Traps (for Russian speakers)
- False friend: 'калория' is a direct cognate with identical meaning, so no trap.
Common Mistakes
- Confusing 'calorie' (cal) with 'Calorie' (kcal). Saying 'This has 100 calories' when the label says '100 kcal' (which is 100,000 small calories). Using 'calorie' as an adjective without a hyphen (e.g., 'calorie food' instead of 'high-calorie food').

FAQ
Frequently Asked Questions
No. The Calorie (capital C) on food labels is a kilocalorie (kcal), equal to 1000 small calories (cal) used in physics/chemistry.
For weight gain/loss, the calorie balance is primary. However, for health, body composition, and satiety, the source of the calories matters significantly.
It's a simplified, often debated statement meaning that from a pure energy balance perspective, all calories provide the same amount of energy. It ignores the complex metabolic and hormonal effects of different foods.
It varies greatly by age, sex, weight, height, and activity level. General guidelines exist, but individual needs are best determined by a healthcare professional or registered dietitian.
