Dietary energy requirements of young adult women in China by the doubly labeled water method.

Objective: The current recommendations on dietary energy requirements in China have been based on total energy expenditure (TEE) derived from theoretical factorial calculations expressed as multiples of basal energy expenditure (BEE).
