¿Cuál es la diferencia entre 'estar a dieta' y 'hacer dieta'?
Both phrases mean 'to be on a diet' or 'to go on a diet.' 'Estar a dieta' (to be on a diet) emphasizes the current state or condition. 'Hacer dieta' (to do a diet) emphasizes the action of starting or undertaking the plan. Both are common and interchangeable in many contexts.
