Lifestyle and Weight Loss For Teens

Your teenager is suddenly eating more, gaining weight, dealing with acne, and asking for another snack an hour after dinner.

Is this just normal puberty?

Or could insulin resistance be playing a role?

The answer isn't always obvious because puberty itself naturally causes temporary changes in insulin sensitivity. Growth hormone rises, appetite increases, teens gain weight, and their bodies need more energy to grow.

But there are certain signs that make me look more closely for insulin resistance.

In this episode, I explain the difference between normal puberty changes and warning signs that may point toward insulin resistance or prediabetes. Puberty changes a teenager's metabolism. But we shouldn't automatically assume that every change is "just puberty."

Knowing what to watch for can help you recognize when your teen may need more support.

I’m Dr. Jenny Gourgari—pediatric endocrinologist, certified in obesity medicine and a health coach. 
After helping hundreds of teens struggling with insulin resistance, prediabetes and their hormones, I’ve created a whole new path by doing what most programs miss: balance puberty hormones naturally and create healthy habits that actually last.

Here's what makes this different:
✅ No dieting. No calorie counting. No shame.
✅ No more food fights between parents and teens.
✅ No weight obsession—just healthy habits
✅ Real science behind how puberty hormones affect weight
✅ A safe, supportive approach that prevents eating disorders

Because when teens understand their hormones and get the right support, they don’t just lose weight—they gain strength, energy, confidence, and freedom!

20 High -Protein Snack Ideas for Teens with Insulin Resistance and Prediabetes

If you've ever told your teen with insulin resistance/ prediabetes "don't eat that"... and watched them eat it anyway, this episode is for you.
 
 Teenagers are wired to push back on rules, and food is no exception. In this episode, I share why strict diets and banned foods backfire with teens who have prediabetes, and what works better.
 
 In this episode:
 • Why I personally can never follow a diet (and why your teen can't either)
 • What the research says about dieting in adolescence
 • Why the locked snack cabinet doesn't work
 • How protein helps your teen feel full and crave less
 • Simple fiber swaps: brown rice, whole wheat pasta
 • Pizza night, pasta night and taco night, upgraded (yes, you keep them)

Do you ever say, “I’m too lazy to exercise,” or wonder why you cannot make yourself go to the gym?

You are not lazy. Starting is simply harder when exercise is not yet part of your routine.

After returning from my summer vacation in Greece, I struggled to get back to the gym too. I made excuses, missed workouts, and felt guilty. Then one phone call from a friend changed everything.

In this episode of The Lifestyle and Weight Loss for Teens Podcast, I share what helped me start moving again—and how the same ideas can help teenagers build an exercise routine without guilt, shame, or pressure.

Your teen does not need to begin with a hard workout or spend an hour at the gym. Walking the dog, swimming, dancing, playing basketball, or taking a short walk with a friend all count.

The goal is not to be perfect. The goal is to make starting easier.

If your teen needs help building healthier habits, join the 7-Day “Healthy Weight Starts With Healthy Habits” Mini Course for $25. Small actions can become habits that support better energy, confidence, and health.

A friend of mine, who's also a doctor, called me about a patient: a patient she's trying to help reach a healthier weight. Her question was simple. "Should I put them on a glucose monitor? They do not have diabetes, they just want to lose weight".

If you've seen these little sensors all over your feed, you've probably wondered the same thing. So in this episode I give you the honest answer.

Here's what we cover:

1. What a continuous glucose monitor actually measures, and why it's lifesaving for teens with diabetes
2. Why "a screening tool, not a treatment" is the clearest way to think about it for everyone else
3. What the research really says about teens without diabetes
4. The quiet risk of number-watching, and how it can push a teen toward fearing food
5. What actually helps a teen improve insulin sensitivity, without dieting

All the best,

"Just eat less and move more." If I had a dollar for every time a teenager or parent told me they received this advice, I could fund a research study.

It sounds logical. It works for some adults in some situations. But for teenagers dealing with insulin resistance, prediabetes, PCOS, or weight struggles during puberty, this advice is not just unhelpful. It misses the point entirely.

In this episode, I am sharing three specific reasons why the eat less, move more approach fails teenagers, and what actually works instead. And I am being personal about it too, because I was that teenager. I tried the tomato diet at 11 years old. I hated PE. I was always last in line when the teacher asked us to run. So I know this from the inside, not just from the clinic.

"He will grow out of it." "Let's just keep an eye on it." "He is a teenager, this is normal."

I hear these phrases from families all the time. And I completely understand why. Waiting feels reasonable. But when it comes to prediabetes in teenagers, the wait and see approach is not always the right one. And today I want to explain exactly why, using data from a major NIH research study that changed how I think about this.

Because here is the thing most parents and even many doctors do not realise. Prediabetes in a teenager is not the same condition as prediabetes in an adult. The biology is different. The progression is different. And the window to reverse it is real, but it is not unlimited.

A normal A1C result feels like good news. And I completely understand why parents feel relieved when they hear it. But as a pediatric endocrinologist, this is one of the biggest misunderstandings I see in families, and I want to clear it up today.

In this episode I explain what A1C actually measures, why it misses early insulin resistance in teenagers, and the other lab values and physical signs that pediatric endocrinologists look for when they want to catch metabolic problems before they become prediabetes or diabetes.

Do you worry your teen is gaining weight quickly or seems hungry all the time?
Are you afraid this could lead to prediabetes or diabetes later in life?

That’s why I created the “Healthy Weight Starts with Healthy Habits": A 7-Day Hormone Reset Program for Teens.

20 High -Protein Snack Ideas for Teens with Insulin Resistance and Prediabetes

Everyone is talking about Ozempic, Wegovy, and GLP-1 weight loss medications for teenagers. But there is one critical piece of information that almost nobody is discussing. And as a pediatric endocrinologist who prescribes these medications regularly, I think every parent and teenager considering them needs to hear it.

In this episode, I am breaking down what the clinical trials actually showed, what the numbers really mean, and what happened to the teenagers in those studies who did not take the medication at all. Because the answer might genuinely surprise you.

What you will learn in this episode:

How GLP-1 clinical trials actually work, and why the results are more nuanced than headlines suggest

What percentage of teenagers achieved meaningful weight loss with Wegovy and semaglutide 

What percentage achieved the same meaningful weight loss without any medication at all (and this number is important)

Why all GLP-1 trials were conducted alongside intensive lifestyle modification programs, and what that means for real-world results

The minimum contact support that research shows is needed for lifestyle modification to be effective

Why teenagers who had previously failed lifestyle modification achieved results when placed in a structured, supervised program for a full year

The muscle mass side effect of GLP-1 medications and what reduces it significantly

What happens to weight when GLP-1 medications are stopped, and why lifestyle change cannot be taken away.

Do you worry your teen is gaining weight quickly or seems hungry all the time?
Are you afraid this could lead to prediabetes or diabetes later in life?

Are the foods your teen eats every day actually helping their metabolism… or keeping insulin high all day long?

I go over 7 foods that are commonly marketed as “healthy” for teens — but may contain hidden sugars that contribute to cravings, fatigue, increased hunger, and weight gain over time.

You’ll learn:

•  Which foods may not be as healthy as you thought
•  Simple swaps that support healthier hormones and metabolism
