That is the worst diet in the world, She could do herself so much better by just concentrating on her diet. She is actually hurting herself by not creating a good environment for her insuling respose.
I bet she is what we call "skinny fat" That means she is skinny but she is squishy if you know what I mean. One meal a day is not healthy, especially by sucking down sugary energy drinks all day.
Her doctor should get involved and correct thgis problem immediately.

Whether you think can or think you can\'t, you\'re probably right!
