For a 12-year-old female, being underweight means having a Body Mass Index (BMI) below the 5th percentile for her age and gender, which varies with height, but generally, weights below approximately 68-72 pounds (around 31-33 kg) might be considered underweight, though a healthcare professional needs to use growth charts for an accurate assessment. It's about growth patterns, not just a single number, so consulting a doctor using tools like BMI-for-age percentile charts is essential.
To tell whether a young adolescent has a healthy weight, it can help to know the average for their age and sex. The averages for 12-year-olds are 89 pounds, for males, and 92 pounds, for females.
For a start, the average weight for 12 is only around 40--42 kg. However, we can say that at 12 years many American kids are already overweight. So while it is NOT uncommon to be a bit overweight, or in your case, maybe obese, it's not healthy.
According to the CDC, most 13-year-old females weigh between 76 and 158 lb . The 50th percentile for weight in this group is around 101 lb. This means that about 50% of girls this age weigh less than 101 lb. If a 13-year-old girl weighs under the fifth percentile, a doctor may classify them as being underweight.
Key Takeaways. A healthy weight range for a 12-year-old girl is approximately 68 to 125 pounds (31-57 kg). The median weight for a 12-year-old girl is approximately 90 pounds (41 kg).

To help figure out if your child is too skinny, here's what to know. Children are considered underweight when their body mass index (BMI) is below the 5th percentile for their age and gender on growth charts, according to the CDC study.
What exactly counts as being "skinny?" Some healthcare experts believe a BMI in the 15-18 range to be clinically underweight. This seems to fall pretty close to what many everyday people consider to be "skinny" with a BMI of 18 or lower frequently listed as the indicator of someone considered to be slim.
Noticeable weight gain may occur prior to a growth spurt as excess fat helps promote growth. As a child goes through puberty, their stores of body fat may change. For example, girls tend to gain more fatty tissue in the hips, thighs and buttocks, while boys may have an increase in fat on their stomachs.
A good measure of whether you are a healthy weight is the body mass index (BMI). This is calculated using your weight (in kilograms) and your height (in meters squared). For most adults, a healthy weight range is a BMI of 18.5kg/m2 to 24.9kg/m2. If your BMI is under 18.5kg/m2 then you would be considered underweight.
More significant weight gain is normal during the preadolescent ages of roughly 9 to 12 and adolescence – as a child matures into a young adult. It's not unusual for the body to store fat during this time as it prepares for the rapid growth and changes associated with puberty.
Problems with the digestive system can prevent a child from gaining weight. Conditions like gastroesophageal reflux (GER), chronic diarrhea, cystic fibrosis, chronic liver disease, and celiac disease can make it harder for kids to absorb enough nutrients and calories to gain weight. Food intolerance.
BMI is used mainly to define different weight groups in adults age 20 years or older.
Your body may lack the nutrition it needs to maintain its tissues and functions. If your BMI is below 18.5, you should see a healthcare provider for testing. Having underweight can cause serious health risks or be a sign of a serious underlying condition.

Understanding the 3-3-3 Rule
Specifically, the rule suggests: Three balanced meals per day. Three hours between each meal. Three hours of movement per week.
“It's normal for a child to slim down between ages 2 and 5,” says pediatrician Roy Kim, MD. “Your child will look their thinnest about the time they start kindergarten.”
This sensory focus helps interrupt escalating anxiety and supports calming responses. The rule is easy to apply in everyday situations. Children are guided to name three things they see, three things they hear, and move three body parts.
Too Skinny: What BMI is Considered Underweight? From a clinical perspective, an individual is considered “too skinny” if they are deemed underweight. According to the Centers for Disease Control, an individual is underweight if their Body Mass Index (BMI) is below 18.5 [1].
Underweight: BMI is below the 5th percentile age, gender, and height. Healthy weight: BMI is equal to or greater than the 5th percentile and less than the 85th percentile for age, gender, and height. Overweight: BMI is at or above the 85th percentile but less than the 95th percentile for age, gender, and height.
