For the Xianzhou's long-life species, eating well and growing taller had no necessary connection.
The height of a long-life species was determined at birth.
How much they ate afterward could probably only affect their width.
At Fu Xuan and Qingque's age, their height had long since stopped changing.
Fu Xuan usually ate very little. Most of her energy intake came from medicinal tea with copious amounts of sugar added.
Perhaps calling it sugar water would have been more accurate.

Despite drinking it every day, Fu Xuan had not become fat and instead maintained a slender figure, entirely thanks to how much energy her brain consumed.
Research suggested that a person's brain accounted for roughly twenty to thirty percent of their total daily energy expenditure.
That was for an ordinary person.
But if someone performed intensive calculations or thinking, engaging in strenuous mental work every day, that proportion would rise sharply.
For someone like Fu Xuan, physical labor accounted for very little of her energy expenditure. Nearly all the energy she took in was consumed by her brain.
It was difficult for her to gain weight that way.
