Healthy Living Blog: Is Biohacking the New Diet Culture? What Midlife Women Need to Know About Peptides, Hormones, and Body Image with Karen Martel

https://ift.tt/xi2OYIe

Have you ever caught yourself counting calories out of habit, even when you know better? Or scrolled past a before-and-after photo and felt that familiar pull of “maybe I should try that too”? If you grew up in the 1980s or 90s, chances are diet culture didn’t just influence you; it shaped the very way you think about your body, possibly without you even realizing it.

That is the conversation I wanted to have on this episode of Midlife Conversations, and I could not think of a better person to have it with than hormone health expert and podcast host Karen Martel. Karen grew up with a mother who literally ran a weight loss center. Food, restriction, and body scrutiny were not just household topics; they were the family business. And yet today, Karen helps midlife women untangle their relationship with hormones, weight, and the stories they have been carrying since childhood.

What I did not expect walking into this conversation was how much it would shift my own thinking. We started in one place and ended up somewhere I genuinely had not anticipated. That is the kind of episode this is.

You Did Not Escape Diet Culture. You Just Got a New Version of It.

Most of us think we have moved past the fat-free craze, the Tab sodas, the “eat less, move more” lectures. And in some ways, we have. But Karen makes a compelling case that the underlying belief, that there is always something about your body that needs fixing, never actually went away.

It just rebranded.

What was once grapefruit diets and HCG injections is now biohacking stacks, peptide protocols, and 72-hour water fasts reframed as “mental clarity cleanses.” The packaging changed. The obsession did not.

Karen knows this firsthand. Growing up with a mother who monitored every bite she ate and openly expressed distress at any sign of weight gain, Karen developed bulimia as a teenager. The weight gain that triggered it? Largely the result of being put on birth control pills at 13 for acne, something her mother never connected to the sudden physical changes happening in Karen’s body. Instead, the message was: eat less, exercise more.

That message, delivered early and repeatedly, does not just disappear when you grow up. It lives in the background, shaping decisions, fears, and behaviors for decades.

The Mom Effect: What Our Children Are Actually Learning

One of the most honest and relatable threads in this conversation was about raising daughters in the shadow of our own food stories.

Both Karen and I have been acutely aware of not repeating what was done to us. We made deliberate choices not to comment on our daughters’ bodies, not to talk about our own weight struggles in front of them, not to make food a source of anxiety. And yet.

Karen’s daughter still absorbed it. Mine did too. Because children do not just hear what we say. They watch what we do. They see the behaviors, the preoccupations, the subtle tension around mealtimes. Silence around food can communicate just as much as commentary.

What Karen eventually realized, and what resonated deeply with me, is that going completely silent created a different gap. Her daughter grew up wanting to understand nutrition but felt she had no one to ask. The pendulum swung from “constant scrutiny” to “total avoidance,” and neither extreme served her.

The middle ground, educating without shaming, discussing without obsessing, validating curiosity without feeding fear, is genuinely hard to find. And most of us are still figuring it out in real time.

Calorie Counting, Food Guilt, and Why the Old Rules Will Not Die

Ask any group of midlife women how many still feel guilty after eating something “bad” and the hands go up fast. Karen attributes this to deep neural conditioning, years and years of messaging that started in childhood and was reinforced by culture, media, and often our own mothers.

She makes an important point about how calorie counting became accepted as the gold standard of health for decades, even as the science continued to show that it is, at best, an imprecise system and, for many women, a pathway to disordered thinking. And yet the habit persists. Because the belief that drove it persists.

What would it take to actually rewire that? Karen’s own turning point came in her 30s when she discovered that the weight gain she had been fighting for years was actually hormonally driven, not a failure of discipline. When she finally understood the root cause, she made a decision: no more calorie counting, no more obsessing. She focused on eating to support her body, not to shrink it, and maintained her weight for nearly a decade doing exactly that.

Then perimenopause hit and changed everything again. Which is exactly the kind of plot twist midlife women know all too well.

GLP-1 Peptides: The Tool Nobody Is Being Completely Honest About

This is where the conversation gets genuinely nuanced, and where Karen’s perspective challenged some of my own assumptions.

GLP-1 receptor agonists, including medications like tirzepatide, have become enormously popular among midlife women for a range of reasons: weight loss, inflammation reduction, blood sugar regulation, and thyroid support. Karen works with a telehealth clinic and has seen these medications produce genuinely life-changing results, including for herself.

But she is also unflinching about the risks and the way these medications are being misused on a large scale.

What the responsible use actually looks like

Karen describes a model where women use the lowest effective dose possible, support the medication with adequate protein intake, strength training, and appropriate supplementation, and treat any reduction in appetite as a signal to adjust the dose, not an invitation to eat less. The goal is not to eliminate hunger. It is to quiet the relentless mental noise around food so that women can make nourishing choices without white-knuckling every meal.

She has seen this work beautifully. Women who spent their entire lives thinking about food, planning around it, dreading it, or bingeing on it, describe a kind of mental freedom they have never experienced before. For someone with a long history of disordered eating, that relief is not trivial. It can be genuinely therapeutic.

What the irresponsible use looks like, and why it is spreading

At the same time, Karen is clear: these medications can enable and accelerate disordered eating in women who are already vulnerable. The TikTok trend she describes, women filming themselves “cooking” a syringe as a joke about not needing to eat, is not funny. It is alarming. It is the new face of an old problem.

The body positivity movement that gained real traction in the early 2020s has, in her view, largely been dismantled by the widespread visibility of dramatic weight loss through GLP-1s. The “heroin chic” aesthetic that many thought was buried in the 90s is visibly making a comeback in Hollywood and on social media. The cultural messaging is shifting back toward: smaller is better, and now there is an easier way to get there.

The commitment most people are not talking about

Perhaps the most important thing Karen wants women to understand is that for most people, these medications are a lifelong commitment. Stop taking them, and for the majority of users, the weight returns. This is not a character flaw or a failure of willpower; it reflects underlying physiology. But it means that the decision to start should be made with full awareness of what you are signing up for.

She uses a direct analogy: we do not expect someone with Type 1 diabetes to take insulin “just for a while.” The medication addresses an ongoing physiological reality. For women whose bodies have a strong homeostatic pull toward a higher weight set point, especially in the context of menopause-related hormonal shifts, GLP-1s may function similarly.

The Risks Nobody Is Discussing Loudly Enough

Karen does not shy away from the complications, and she names them directly.

Sarcopenia and bone loss

This is the one that concerns me most. When women severely restrict caloric intake while on GLP-1s, whether intentionally or because appetite suppression is so profound, they lose muscle and bone alongside fat. Muscle loss in midlife is not just cosmetic. It is directly tied to metabolic health, mobility, fall risk, and longevity. Bone loss is equally serious: fracture risk after 65 is staggering, and a hip fracture in that age group carries a genuinely frightening mortality rate. These are not abstract risks. They are real, sometimes irreversible consequences of malnourishment that no one at a prescription clinic is necessarily following up to prevent.

Digestive changes

GLP-1s slow gastric emptying, which is why surgical teams require patients to stop taking them weeks before any procedure. For everyday users, this can manifest as constipation, bloating, and changes in digestive rhythm that need to be actively managed, not just accepted as a side effect.

The research peptide access question

Many women are sourcing compounded or research-grade versions of these medications, and that landscape is shifting. Karen acknowledges that supply and regulatory access could change rapidly, and a sudden loss of access for women who have been on these medications long term could trigger significant physical and psychological rebound. This is not a hypothetical concern.

The prescriber problem

The majority of clinics offering these medications, in Karen’s estimation, are not providing meaningful follow-up education or support. A patient fills out an intake form, receives a prescription, and is largely on their own. The coaching, the nutritional guidance, the conversation about what to do when the food noise starts to come back, that piece is almost entirely missing from most prescription pipelines.

Hormones First: The Step Most Women Are Skipping

One of Karen’s most practical takeaways from this conversation is something she wishes more people would hear before they start a GLP-1 protocol.

Optimize your hormones first.

Many women entering perimenopause or early menopause are experiencing weight gain, inflammation, and metabolic disruption that is directly tied to declining estrogen and testosterone. Estrogen plays a meaningful role in insulin sensitivity, fat distribution, and metabolism. When it drops, the metabolic chaos that follows is real, documented, and not a personal failure.

Starting hormone replacement therapy before or alongside peptide use, and timing it appropriately rather than waiting until menopause is fully established, can make a significant difference in outcomes. Karen has worked with women whose weight began to shift simply by getting their hormones properly optimized, without any peptide intervention at all.

The point is not that one approach is right for everyone. It is that individualizing the care, understanding what is actually driving your symptoms, and addressing root causes alongside symptom management, produces better and more sustainable results.

Empathy Over Judgment: The Framing That Changes Everything

By the end of this conversation, Karen offered a reframe that genuinely landed for me.

We do not judge people for taking antidepressants. We do not scrutinize someone’s decision to manage their cholesterol with medication. We do not ask people with chronic pain to prove they hurt enough to deserve relief.

But the moment weight loss becomes pharmaceutical rather than purely behavioral, a wave of judgment appears that does not exist in any other health context. Karen is not arguing that GLP-1s are without risk or that their misuse is not a real problem. She is arguing that shaming the women who use them, especially women who have spent decades suffering with disordered eating, failed diets, and metabolic disruption, does not help anyone. Empathy and education do.

The woman who is using these medications to finally quiet a food obsession that has consumed her since adolescence deserves the same compassion as anyone else managing a chronic condition. And she deserves practitioners who will actually help her do it in a way that protects her muscle, her bones, her hormones, and her relationship with her body for the long term.

What to Take Away From This Conversation

If you are considering GLP-1 medications, Karen’s guidance is clear:

Work with someone who will individualize your protocol and will not just hand you a prescription and send you on your way. Optimize your hormones first if you have not already. Use the lowest effective dose. Eat enough, prioritize protein, and lift weights. Understand that for most women, this is a long-term commitment, not a short-term fix. And continue doing the inner work around body image, because the medication will not do that part for you.

If you are not considering these medications, but you recognized yourself in the diet culture conversation, in the calorie counting guilt, in the food rules that still run in the background of your thinking, that is worth sitting with too. The beliefs formed in childhood have a long shelf life. And recognizing them is the first step to finally setting them down.
