Physician-Led Pediatric Obesity and Metabolic Care for Families Throughout the Austin Metro
Author: Dr. Natalie Hernandez, Pediatric Endocrinologist & Metabolic and Obesity Medicine Specialist.
If You're Worried About Your Child's Weight, Start Here
Most parents who come to us have already tried everything they know to try.
Their child eats better than most adults.
They've cut back on screens, signed up for a sport, cooked more meals at home.
And the weight still isn't moving the way they'd hoped.
If that's you, we want to say this clearly: you haven't missed something obvious, and your child hasn't failed at willpower.
Childhood obesity is rarely about effort. Genetics, hormones, insulin resistance, puberty, sleep, and metabolism all shape how a child's body stores and uses energy. Real answers start with understanding why, not with another round of "eat less, move more."
Looking for the Top Pediatric Endocrinologist for Weight Loss in Austin?
Dr. Natalie Hernandez is a board-certified pediatrician and fellowship-trained pediatric endocrinologist specializing in pediatric obesity medicine, metabolism, diabetes, and hormone health. She leads metabolic and obesity medicine for LIFE Pediatric Endocrinology, a national concierge practice, and Austin families choose her for physician-led, evidence-based care that looks past the scale to the underlying cause of a child's weight gain.
Why Austin Children Gain Weight
Every child's story is different.
- Some have insulin resistance, which can drive hunger and fat storage even with a healthy diet.
- Some develop PMOS (formerly PCOS), which makes weight management measurably harder — and is often missed until the teen years.
- Some are moving through puberty, which naturally shifts appetite, body composition, and metabolism.
- A smaller number have a specific genetic or hormonal cause that a standard nutrition plan was never going to fix.
Dr. Hernandez evaluates the whole child, not just the number on the scale, because two kids who look the same on a growth chart can have completely different underlying causes, and completely different paths forward.
A Comprehensive Medical Evaluation
Before recommending any treatment, Dr. Hernandez performs a thorough evaluation that may include:
- Growth chart and weight chart review
- Medical and family history
- Physical examination
- Nutrition and sleep assessment
- Physical activity review
- Laboratory testing
- Screening for insulin resistance
- Evaluation for PMOS (formerly PCOS)
- Screening for prediabetes and other metabolic conditions
- When appropriate, genetic testing for early-onset or severe obesity
This is what lets us build a plan around your child's actual biology, not a generic protocol.
You Don't Have to Enroll in a Program to Get Answers
Many Austin families hold off reaching out because they assume the only option is committing to a full weight-loss program.
That's not the case.
Some families come to LIFE for the Confident Body Program, our structured, physician-led approach to pediatric metabolic health that pairs medical care with ongoing coaching. Others come for a single, focused evaluation: bloodwork, a PMOS (PCOS) workup, an insulin resistance screening, or genetic testing for a child whose weight gain doesn't fit the usual pattern, without joining a formal program at all.
Dr. Hernandez will tell you honestly what she thinks your child needs. Sometimes that's the full program. Often, it's far less than families expect.
When Genetic Testing Makes Sense
Most childhood weight gain is multifactorial, genetics, environment, hormones, and habits, all interacting. Genetic testing isn't something every child needs.
But for a smaller group of children, it matters enormously. It's worth discussing when a child has:
- Severe obesity that began very early, often before age 5
- Hyperphagia, an insatiable, hard-to-satisfy hunger not explained by typical eating patterns
- Obesity alongside developmental delay or other unusual features
- A strong family history of severe, early-onset obesity
- Little to no response to standard lifestyle treatment
Rare, single-gene causes of obesity, including POMC, PCSK1, and LEPR deficiency, and Bardet-Biedl syndrome, are uncommon, but they're no longer untreatable mysteries. The FDA has approved a targeted medication for children as young as 2 with these specific, genetically confirmed diagnoses. Identifying the cause can change the entire treatment plan.
Dr. Hernandez can help you understand whether this kind of workup makes sense for your child. Most don't need it, but for the ones who do, it's often the missing piece.
GLP-1s and Other Medications: What Austin Parents Are Asking
Almost every family asks about this eventually, so let's address it directly.
Two GLP-1 medications currently have FDA approval for adolescent obesity: semaglutide (Wegovy), approved for ages 12 and up, and liraglutide (Saxenda), approved for ages 12–17. Both were studied alongside lifestyle treatment, not as a replacement for it, and neither is a first-line default at LIFE.
We don't start with medication. We start with an evaluation. When labs, growth history, and clinical context support it, GLP-1 therapy or metformin may become part of a comprehensive plan, always monitored, always paired with coaching, and always explained clearly before anything is prescribed.
If your child doesn't need medication, we'll tell you that too. Learn more about how we approach GLP-1 medications for kids →
Could It Be PMOS (Formerly PCOS)?
For teenage girls, unexplained weight gain sometimes has a name families haven't heard yet: PMOS, formerly known as PCOS.
Irregular periods, acne, excess hair growth, and weight that resists diet and exercise can all be signs. PMOS is frequently missed in the teen years because its symptoms get dismissed as "normal puberty."
Dr. Hernandez screens for PMOS as part of a comprehensive weight evaluation. Read more about recognizing PMOS symptoms in teens →
How Fast Should a Child Safely Lose Weight?
This is one of the questions we hear most, and one of the most important to get right.
For growing children, the goal is rarely rapid weight loss. In many cases, the real goal is slowing the rate of weight gain while a child continues growing taller, which naturally improves their growth trajectory over time. For adolescents closer to adult height, a more direct, gradual weight-loss goal may be appropriate.
The right pace depends on your child's age, growth stage, health status, and the underlying cause, which is exactly why this should be a physician-supervised decision, not a number pulled from a website. Rapid, unsupervised weight loss in a still-growing child can do real harm.

Frequently Asked Questions (FAQ)
Does my child need a referral? No. Families are welcome to schedule a consultation directly with our Austin office.
Do we have to enroll in the Confident Body Program? No. Some families join the full Confident Body Program; others come for a single evaluation, PMOS workup, or genetic testing without enrolling in a formal program. Dr. Hernandez will recommend what actually fits your child.
Will my child need a GLP-1 medication? Not necessarily. Lifestyle treatment remains the foundation of care. When medically appropriate, FDA-approved GLP-1 medications like semaglutide (Wegovy) or liraglutide (Saxenda) may be recommended as one part of a comprehensive plan — never as a first step, and never without monitoring.
Is genetic testing right for my child? For most children, no — most childhood weight gain has several ordinary, overlapping causes. Genetic testing is most useful for children with very early, severe, or unexplained weight gain, especially alongside intense, hard-to-satisfy hunger. Dr. Hernandez can help you decide if it's worth pursuing.
Could my daughter's weight be related to PMOS (PCOS)? It's possible. Irregular periods, acne, excess hair growth, and treatment-resistant weight gain can all be signs of PMOS, and it's commonly missed in adolescence. A comprehensive evaluation includes screening for it.
Does insurance cover care at LIFE? LIFE Pediatric Endocrinology operates on a concierge model. Our team will walk you through program details, pricing, and options during your consultation.
How is LIFE different from other pediatric weight-loss programs in Austin? We're led by pediatric endocrinologists, not a generalized weight-loss clinic. We look for the underlying medical and metabolic causes of weight gain, insulin resistance, PMOS, prediabetes, hormonal conditions, and in rare cases, single-gene causes, rather than starting and stopping with calories.
