DD (10) and weight worries

[perhapstomorrow]

Not sure if this is the right place to post but I'm in need of some guidance.

My DD used to be very active and a result was very lean. She is now doing less sport so has put on a little weight. She has also slowed down in her growing. She has now put a bit of weight on and where she almost had a 6 pack she is looking a bit rounder. She had the year 6 height and weight measurements and is at the very top end of normal.

She is now becoming very concerned about her weight. She is always saying she is fat and she pulls at her tummy. It wasn't helped by a boy in a class calling her fat and laughing at her in a gym class.

I am so unsure of what to say to her in case I make things worse. I want to support her but don't want to make food and her weight a big deal. This morning she didn't have breakfast and had a mini meltdown over her lunch. I am sure this is to do with her concerns about her weight.

How would you deal with this? I am trying to get her to eat healthy snacks and we both went on a bike ride this weekend so will continue this way. I am quite unfit so I think I will try and get her to accompany me on walks and rides. She also does other sports but she gave up gymnastics that she was training 6 hours a week with as she kept getting injured. I want to help her but don't want to say/do the wrong thing and make things worse.

TIA

The little [insert swearword] that had the nerve to call her fat needs a good talking to by the school.
I'm sorry if she is feeling body conscious. It's really hard in this weather to get out and active but that's what I would encourage. Country walks/park walks whatever you can manage at weekends. I'm redoing Couch 2 5k with my 10 year old - trust me I am an overweight 50+ with a chronic condition and I completed the programme last month.
Even if she just gets out for a bit of a run/ heart rate increase with me it'll be worth it.

fastasleep I was very angry about this boy but my DD was adamant she didn't want me to raise it with her teacher. I will definitely use this as an opportunity to loose weight myself as I am not exactly a shining roll model. I just don't want this to escalate and for her to become obsessed with her weight and food. I had issues as a teenager so I suppose I am extra sensitive to it.

Just do a general "move more/eat fresher" kind of thing for everyone in the house. That should dial it down a notch. If she is adamant she doesn't want it raised then that is her preference. A general word with the teacher for them to do a general "don't be a little shit" talk to everyone might be still worth it.
It sounds like she's got into some great habits and you'd like her not to lose them. See if there is another activity she might like (that perpetual search ). Try some taster lessons for something unexpected. And join in if she can bear you too.
