Snoozan, I know this is a very sensitive subject for you given your recent substantial weight loss. Let's be serious, the girl is gorgeous; but she is overweight. Her stated weight is clearly a lie. I am a size 12-14 in US sizes and if we were to stand next to each other I guarantee you I'd look as scrawny as Irish next to her. Since I am 5'9" and weigh about 176 I can only assume she is lying.
Yes, I am very sensitive about this subject and I will continue to argue with men who call overweight women cows, ugly, fat, unfit, etc. even when I'm a size 6 (US). She's also a size 12-14 US and she's an inch taller than you. I couldn't make the judgement of your versus her unless I saw you both in person or in photo standing next to each other wearing the same thing. Like I said, the camera adds weight. I don't think her stated weight is a lie. You may just carry weight differently than she does.
This is a plus-size model in the same size range as Miss Surrey and she doesn't look all that smaller in a lot of photos (many of which have probably been photoshopped to slim her down a bit):

Miss Surrey is overweight. She is also 16, and an overweight 16 year old is likely to put on even more weight as they stop growing. Her weight does not appear to be distributed as muscle, rather it is simply fat. She has a weight problem, a serious one.
This is a good point, and one that bears some thought. Overweight children turn into obese adults. Girls who, at 15 or 16, are just a little overweight are at much higher risk of being obese as adults. Still, they can be beautiful and fit their whole lives if they are aware of this fact and take care of themselves.
Even though we know her weight (maybe) we don't know her fitness level, body fat percentage, or lean body mass. Because of that, there's no way to how out of shape and at risk for health problems she is. However, she's doing a lot of young women good who aren't able to be what every other girl in that contest is. What we need to do is put less stress on what these girls look like and more on what they are doing to stay fit and healthy. You can be healthy and still be what a lot people think is overweight, fat, or obese. The best person to guage your overall fitness is a doctor or a fitness professional. People have a distorted view of weight and can't be trusted to make what are ultimately medical judgements.
The message presented in sections of the UK press is that it is perfectly okay to be like Miss Surrey and that being her weight is no problem. The message that we should be getting across is that overweight, particularly in a person just 16 years old, is a serious health problem.
Yes, if we're assuming that she's lying about her weight and she doesn't exercise. If she isn't lying about her weight and she does exercise, then shall we have her lose 3 pounds so she's healthy? Or should the winners be less extreme in both directions? Say, 5'10" and 150 pounds, which is a reasonable, well-proportioned weight for a woman who is of medium frame and moderately fit.
I agree there's a fine line between encouraging girls to embrace and accept who they are and making it okay for girls to not to keep themselves fit. I'm not sure how to make the distinction.
This also reminds me of the Kirstie Alley fiasco when she debuted her Jenny Craig weight loss at 145 pounds looking more like she was pushing 185. Who knows what she really weighed.
To each his own; but ugly she is not! You may not like plump women but she has a classic, wholesome beauty.
