That looks lovely. Makes me sad for her. My daughter also had weight problems. She started getting chubby and kept gaining and gaining. Finally at 13, I put us all on Weight Watchers. But the less she ate, and more she exercised, the more she GAINED!! I'm not kidding, she gained 5 lbs in a month. Finally went to the dic about it to learn she was insulin resistant. Most people have insulin levels no higher than 8, maybe 13 if you're pushing it. Hers were 45. Her body thought it didn't have insulin so it kept producing it, which then in turn made her body think it was starving so would produce more glucose, which turned into fat. When she dieted, it went into starvation overdrive.
With medication, she has been able to reduce her insulin levels, though they still range around 25.
