Lifestyle and Weight Loss For Teens
Is your teen showing early signs of insulin resistance and prediabetes, gaining weight too quickly and is always hungry?
Before you try another diet or cut another food group — you need to hear this.
Teen weight gain is rarely about willpower. During puberty, hormones like insulin, cortisol, and estrogen directly drive how your teen stores fat, feels hungry, and burns energy. If no one has explained that to you yet, this podcast is where that changes.
Lifestyle for Teens with Dr. Jenny is built on one belief: No Diets. No Shame. Just Hormones That Work.
Dr. Jenny Gourgari is a board-certified pediatric endocrinologist and obesity medicine specialist — and she knows this journey personally. She spent her own teenage years struggling with weight and chronic dieting before understanding that hormones, not habits, were driving the cycle. Now she helps parents and teens do what she wished someone had helped her do sooner.
Each week, Dr. Jenny breaks down the real science behind teen metabolic health — no shame, no restriction talk, no oversimplified advice — answering the questions parents are actually googling at midnight:
Insulin Resistance — Can we actually reverse prediabetes during puberty, before it becomes Type 2 diabetes?
Blood Sugar & Carbs — How do different foods affect teen energy, mood, and weight gain?
Hunger Cycles — Why does my teen feel hungry an hour after eating a full meal?
Sleep & Stress — How do poor sleep and chronic stress trigger hormonal weight gain?
Puberty Hormones — What’s actually happening in a teen’s body — and what can we do about it?
Whether your teen has been told they’re “borderline” for prediabetes, or you’re simply watching the weight climb and feeling helpless, this podcast gives you a science-backed path forward — without diets, without shame, and without waiting for a diagnosis to take action.
Hit follow. Your teen’s hormones are workable. Let’s start there.

Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
This podcast episode explores the relationship between sleep duration and insulin resistance in teenagers, building on previous discussions about insulin resistance during puberty.
It highlights the importance of teenagers getting the recommended 8 to 10 hours of sleep each night and presents statistics showing that 70-80% of U.S. teenagers fail to meet this requirement.
Two key studies are discussed: one showing that advanced puberty stages are linked to reduced sleep duration, and another indicating that teenagers sleeping less than six hours have higher levels of insulin resistance.
Practical tips are provided to help teens gradually increase their sleep duration, which can improve insulin resistance and balance puberty hormones.

Hello, welcome to another episode of this podcast. I decided today to talk to you all about the relationship of sleep duration and how that affects insulin resistance in teenagers. In the previous episodes, I talked a lot about insulin resistance in puberty and how that affects It's the journey of teenagers that want to get into a healthier episode.
So you can go back and listen to episode 55 if you 56, if you have not listened to it. And this is a continuation of that episode. And I'm going to focus on one aspect that makes insulin resistance 📍 worse teenagers. And that is sleep duration. So I will be talking also Some basic facts about sleep, they could sleep in teenagers and a couple of studies that showed how big of the problem is and how that affects insulin resistance.
So in general, the recommendation. for teenagers is to get 8 to 10 hours of sleep every night. That is because when teenagers go through all those physical changes, that's a big stress for their body. So they need to have a lot of, at least 8 to 10 hours to give their body enough rest. They also have a lot of homework, a lot of activities and all those things that increases the need for teenagers to get at least 8 to 10 hours.
Now, I know from experience that this is not happening, and it's not only my experience, but in fact, there are statistics, official statistics, that they have been done in United States and show that 70 to 80 percent of teenagers in this country do not get the recommended amount of sleep, do not get 8 to 10 hours of sleep.
And that is very unfortunate because not getting enough sleep can have implications about their, how that regulates their puberty hormones. And today I will be focusing on the effect of lack of sleep on insulin resistance. So there was this great study that was done a few years ago. It was published in the American Journal of Human Biology.
The title of the article is the association between pubertal status and sleep duration and quality among a nationally representative sample of U. S. adolescents. And it's a great study because it was done in more than 2, 000 teenagers. In schools in the United States, where they went, they asked them about their puberty, they asked them about how many hours they sleep, and what they found is that the more advanced their puberty development was, the less they slept.
As teenagers, progress through puberty, instead of sleeping more time, because their body needs more time to rest from all those changes of hormonal, of hormones that happen, they actually sleep less. And another study that I want to mention that looked even more into insulin resistance and sleep duration in teenagers.
Again this was a great, excellent study that was done in 2012. The topic of the title of the manuscript is Sleep Duration and Insulin Resistance in Healthy Black and White Adolescents was published in the Journal of Sleep in October 2012. And what these researchers did, they examined 245 high school students.
Again, they asked them about how many hours they sleep, and then they actually measured their insulin. Scientists have certain ways to calculate the insulin resistance. They measure the sugar, they measure the insulin, and then they measure the body mass index. If you don't know what body mass index is, you can go and listen back to episode one of this series.
And basically they, what they found is that the teenagers that did not sleep enough. And in particular, the teenagers that slept less than six hours, they had higher levels of insulin resistance. And what that means is, if the teenagers that slept less than six hours When they ate carbohydrates and they ate dessert, pasta anything, pizza, and things like that, they have a lot of carbohydrates, their pancreas had to produce lots and lots of insulin in order to prevent them from getting diabetes.
So they were in a state of insulin resistance that leads to prediabetes that has a higher risk to lead to diabetes. And taking all this data into consideration, I want to stress one more time the importance of sleep to regulate the pubertal insulin resistance. It's a simple maybe not so simple, but, a natural way, let me say, that teenagers can implement to improve the insulin resistance of puberty.
By sleeping better by sleeping more time, and it doesn't have to be like, two hours more even if you can sleep every day, half an hour more or an hour more than what you did last month, that is improvement, like even prolongation of sleep by one hour, even by 30 minutes, every little bit of that counts.
And it may be helpful to if you have any tracking device that can monitor your sleep, see if that may motivate you, but you really do not need that. You can just also simply keep a calendar with your bedtime routine, what time you go to bed, what time you wake up, and see whether you can improve that.
And I will be talking more about sleep hygiene and how we can improve sleep in future episodes, but I wanted to Pass out the main message which is not lack of enough sleep in teenagers is a reason that is associated with insulin resistance and any effort that targets a better sleep, more sleep can lead to healthier insulin, can lead to pubertal hormone balance.
I hope this was helpful and I will talk to you next week. Take care.
