Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'рацион' (ration) which is more about provisions. The primary Russian equivalent for the habitual meaning is 'питание', for the restrictive plan it's 'диета'.
- The English verb 'to diet' is active (She is dieting), whereas Russian often uses a reflexive construction 'сидеть на диете' (to sit on a diet).
Common Mistakes
- Using 'a diet' to mean just one meal (e.g., 'I had a healthy diet for lunch' - incorrect).
- Using the verb 'to diet' in continuous forms for permanent states (e.g., 'I am dieting all my life' - better: 'I watch my diet').
