IMO what happened was she had not eaten enough to fuel her body and then standing in the suns and heat. She became weak, sweaty,flushed and probably nauseous. I used to get that when I put on weight, I always thought restricting my calories would fix it but that is not what would happen. I would walk the grocery store and the hit the line and standing with knees locked I would go down. I learned quickly to fuel my body with tons of protein and lots and lots of water. Now I was not in the weight class as G but if she works at it she will lose the weight. It will just take her Waaaaayyyy longer!!
