Maybe they are referring to this. Eteti does seem to praise her ability to survive on powdered diets to loose weight.

Tutberidze has said that Lipnitskaya has amazing willpower. “I have never seen anything like it,” said Tutberidze. “She can practically not eat anything. When she has to lose weight, all she eats is powdered nutrients, which give her energy. But she manages, thank God. She is intensely driven.”
That's a good valid interview, it is often used in other articles. It also contains the part where Tutberidze is explaining why she hired Julia’s mother to look after Julia (same as my earlier article).
I can't find an interview on line, so for what it is worth, there is one where Julia said "we/me and mother, consulted many dietitians and they advised us which substance to use". Julia is not blaming Tutberidze, according to this article/quotes:

“Unlike Antipova, Julia is not accusing her coach of anything (regarding anorexia). She did not explain how she reached this condition”.
I think Julia knew she had to keep a certain weight in order to jump. She did whatever she had to in order to keep it. Her mother helped her with the process, and Tutberidze did not stop her. Tutberidze's position is understandable...... mother's participation is questionable.
Julia is said to be predisposed to weight gain, she knew it, mother and trainer knew it. Julia had to keep to a certain weight to perform. She and her mother had a choice, to take powder and go to the top. Or not take powder, and accept lesser results. They chose powder. Tutberidze did not stop them. But she certainly did not handed the powder to Julia and gave her a condition "powder or no training"....

Times: If Tutberidze refused to train me, I would quit skating.

There are coaches and trainers which push their athletes to go on a diet from day one, and keep flaming their insecurities. But NONE of the other Tutberidze's girls have this issue.... Med gobbles up Sushi and Udongs like there is no tomorrow, she eats like a horse (so the blogs and instagram stuff shows).

Julia was not lucky with her body type... that's all.
