TeenHealthFX thinks that it is wonderful that you are so concerned about your sister. Her current weight does compromise her physical well-being, but also her emotional well-being if she is being teased by peers. FX thinks that the most helpful thing you could do for your sister would be to make some new family goals when it comes to being active and eating in a healthy way. Talk to your parents about having a family meeting where you can all brainstorm ways in which all of you can help each other to make healthy changes to improve overall physical well-being. If the family works together on making healthy changes, your sister will not feel singled out – in fact, it shouldn’t even be presented that this being done for her, but rather for everyone’s benefit. If the family works together and the household environment becomes one with a focus on healthier eating and being more active, there is also a greater chance that your sister will adopt these lifestyle changes more permanently than if the focus was just on a diet.
At your family meeting, consider discussing the following:
By making these kinds of changes together as a family, your sister will not feel singled out, everyone in the family will benefit in terms of their physical well-being, and focusing on overall lifestyle changes rather than short-term dieting will have more of a chance of a lasting effect on everyone involved.
As for your question about your height and weight, FX calculated the body mass index (BMI) of a 13 year old weighing 98 pounds at 5’4” and found that you have a BMI of 16.9 which puts you in a healthy weight range. One useful way to determine whether someone is in a healthy weight range is by calculating their BMI. BMI is a calculation that uses height and weight to estimate how much body fat someone has. It is used to determine how appropriate a person’s weight is for a certain height and age. There are different BMI calculators used for children and adults. The Centers for Disease Control and Prevention explain on their website what the BMI is, what various BMI findings indicate, and how to calculate your BMI based on height and weight.
