Many things she is correct about...for example obesity doesn't cause diabetes. You are either genetically predisposed to an increased risk or you are not.
But if you are genetically predisposed, then obesity increases the risk. Same with heart and vascular problems.
Far more important though is increasing your activity levels and improving muscle tone and strength. Muscle is fab at burning blood sugar. I monitor my glucose levels twice a year with a blood test which shows a trend for how it's been. My levels massively dropped when I began exercising regularly....even with no weight loss.
If you have increased your activity, and increased your muscle mass, then you can remain at the same weight while reducing your fat levels. You now have a higher muscle:fat ratio. Muscles is denser than fat and weighs heavier.
You have, whether you realise it or not, reduced the amount of fat your body is carrying. This is also much better for your joints (joints suffer horribly when you are obese) because muscle is "self-supporting", being active; fat is just dead weight.
Health is a social construct though apparently. And Victoria isn't overly well, she has hypothyroidism, depression etc. She's prone to weight gain just because of that.
And yet she still insists that "health is a social construct"?
Good for her for not being bullied by society regarding her weight, but I really think that she was very happy to be the smallest of the girls, and that she wanted to keep it that way. She didn't want any of the others to lose weight, even though they wanted to lose it, for health reasons and because they didn't like the look of themselves. That is possibly a mental health reason.
She was trying to persuade the others, men and women, to stay fat - she didn't even have the courtesy to hear out a man who had come to talk to them about how his obesity had limited his life, leading to an amputation.
She struck me as being totally closed-minded about anything she didn't agree with. She didn't want to listen to other people's opinions, or experiences, or feelings and she completed denied the facts about obesity.
