OP if I was you I wouldn't take advice either from dieters or from people who are overweight. Obviously none of their approaches to food actually work and they very often have an actively disordered attitude both to food and to weight.
karamair you’ve asked several times if I am a dieter, so I’m going to address your question now that I have time.
I would say no, overall. I’m in my mid-late 40s and never, ever been overweight until 45, when my BMI was 26. After 6 months of 5:2 my BMI is back to 22 and has stayed there. Micheal Moseley (you know, the one whose article you linked to) was the first advocate for intermittent fasting and considers it a way of eating, not a diet. I’ve kept it up because I like it and there’s a clarity of thought that comes with it. Prior to this likely change in my metabolism my approach to food was like yours and this weight gain was a shock. I have an athletic background and ate food when I was hungry. How have you coped with the metabolic changes associated with perimenopause and 4 children?
I’m answering this personal question of yours because it’s worthwhile emphasising that women’s and girls’ bodies are scrutinised and objectified from toddlerhood, much more than those of boys and men, and extra weight is treated as something shameful, or, as per your above post, something that invalidates your opinions. I find this inherently misogynistic, given that many women’s bodies change markedly after childbirth or during the menopause.
I’m not ashamed that, in association with perimenopause and after 4 children, my weight transiently crept up. I’m pleased I’m slim again but it doesn’t make my opinions more or less valid.
I think it’s shameful that you are inferring (not suggesting) that those overweight parents who may be reading these threads aren’t capable of feeding their children properly. My opinion about children’s diets are no less valid with a BMI of 26 than 22, and the women reading this whose BMI is on the high end are no less capable of ensuring their children eat well.
You’ve accused me of “obsessing” over this girls’ weight and never have I once done this. I agree with you about food quality and I agree with the OP that her daughter’s diet isn’t great.
I have suggested that she up her exercise significantly because this will likely normalise her appetite. More importantly, as I stated upthread, it’s important that girls learn that their bodies are functional and strong and vigorous exercise shifts the focus from how they look to what they can do. (It’s also useful from a metabolic perspective, in that children with type 1 diabetes often need less insulin when they exercise vigorously, even if that seems counterintuitive).
My daughter who sounds similar to OP’s daughter, (which is why I posted) eats much better - less mindless carby snacking and more eating of protein and veges - since she started swim training. There was no need for me to change my perfectly adequate meals for her which is what you’re suggesting the OP do.
