I answered in your other thread that puberty and the hormonal changes it brings can cause weight gain.

I have to say, without wanting to offend you, it concerns me you know how much she is putting on each week to the gram. Do you weigh her??? I am not sure that is a good thing for a young teenage girl.
Hi,

I understand that you're concerned, but I do not think it is normal or healthy to focus on a young girls weight with weekly weigh-ins. Or is it daily, since you say she's gaining over the weekned and losing midweek?

Does she look like a healthy weight? Does she have any other signs or symptoms which suggest there might be something wrong? Please don't allow your own concern to cause her to develop an unhealthy obsession on her weight.
I also answered in your other thread too.

Perhaps you should see a GP without your DD first to express your concerns and see what they suggest.

It also concerns me regarding the gram count that's going on. It would be horrific if she had an eating disorder because she is 'trying to do the right thing' by you. Teenage girls have enough peer pressure to be thin without being told they've gained 200g.

I understand you are concerned but I think you may need to take a step back and think about the message you are sending her sub consciously. Are you over weight or struggled with weight? Do you monitor your own weight like this too?
No, I am not overweight myself, never have been. I don't really struggle with my weight, but I compete in triathlons, so I am always training (6 days a week) and am very aware of what I eat, and how it affects my weight.

Yes, she weighs herself on Monday and Friday. I know it sounds harsh. But her weight has been an issue for years and years. This way she is able to see the consequence of her unhealthy choices ... and that's the way we talk about it, health. Her Dad's family has several heath issues (diabetes, heart issues, arthritis) all of which can be connected back to their lifestyle. And when we talk about her weight, it is always about getting healthy, not skinny. I don't want her to end up with a health issue later in life because I didn't do everything in my power to help her.
