See Michelle’s Top 3 Takeaways

Before giving birth in May 2015, I developed gestational hypertension. Despite concerns that it could lead to additional health complications — such as placental abruption, premature birth, or organ damage — I delivered a healthy baby girl.

Over the next year, my blood pressure remained high, and I wasn’t able to lose weight. At a checkup, my doctor noted that Black women tend to be overweight, and he recommended increasing the dose of the hypertension medication I’d started after my daughter was born. He did not suggest lifestyle modifications, like changing my diet or exercising more.

I’m a healthcare researcher, so I knew that his statement concerning Black women was statistically correct. Based on the data, the number of higher-weight Black women is disproportionate compared with other demographic groups for reasons that aren’t entirely understood. A partial explanation is well-established, however: Body mass index overestimates obesity in Black people because it doesn’t account for differences in body composition.

Nevertheless, this didn’t necessarily apply to me — I hadn’t been hypertensive or overweight before I tried to get pregnant. I wanted to find the root cause of my hypertension and weight retention, and I wanted to focus on lifestyle changes before I treated the problem with more medication. I hoped to find another physician to partner with on this wellness journey.

 

Rising Pressure

I got pregnant in 2014, about a year after marrying my college sweetheart. I was a little underweight after my first trimester, so I started drinking protein shakes with breakfast.

Living in Chicago helped too — the city is full of great food. My husband and I ­enjoyed eating at nearby burger joints, taco bars, and pizza places. I made friends with the baker at a local doughnut shop, who always waved me in and gave me one of my favorite glazed long johns.

By the middle of my third trimester, I had gained almost 55 pounds. My blood pressure had also increased — so much so that my physician advised me to come in every other week for checkups. At the time, I didn’t think much about the condition. I felt OK and I’d been reassured that my numbers would normalize after giving birth.

People with hypertension may not experience symptoms, so the condition is not always taken seriously. But it is a genuine threat to health, known as a “silent killer.” Gestational hypertension increases blood-vessel resistance, reducing blood flow to the mother’s essential organs and the placenta. This has the potential to deprive the developing baby of necessary nutrients and oxygen.

We were lucky. Although my blood pressure remained high during the weeks leading to my due date, my baby, Sarai, was born in good health.

The Fourth Trimester

Four months after I gave birth, my healthcare provider advised that I start taking a low-dose medication to manage my blood pressure.

I was having a difficult time ­recovering physically and emotionally from childbirth. The experience had been hard on my body, and adjusting to life with a newborn was a challenge — even with the help of my mother and mother-in-law. Sarai wasn’t feeding well, and she was sleeping all day and awake all night.

At a six-week follow-up visit, I was diagnosed with postpartum depression. I started seeing a therapist on a regular basis, and she helped me learn how to prioritize my own needs while figuring out how to take care of Sarai. I began by simply making sure I was eating, showering, and getting some sleep.

By November 2015, I was starting to adjust to my new life. But my blood pressure remained high. For months I had been living in survival mode. I ate as I had during pregnancy, not thinking about sodium or macronutrients, and I felt more stressed. I lacked the capacity to focus on better nutrition or exercise.

But now that I was finding balance in other areas of my life, I felt ready to address the root causes of my high blood pressure.

I found a new doctor who was willing to focus on nutrition and exercise before increasing my medication. It was the ­motivation I needed to make a change.

Taking Back My Power

I began working with a nutritionist who recommended I reduce sodium and take a month off from eating out. To follow this advice, my husband and I became more intentional about grocery shopping. I focused on produce and meat and was mindful of food labels. On Sundays, I prepped food for the week ahead.

I also made exercise a priority. I’d been athletic as a child and young adult: I played basketball and volleyball in high school and continued with basketball through college. But fitness took a back seat after I graduated. With my health on the line, it was time to tune in to my once-active spirit. I started by attending fitness classes two or three times a week.

Although ­results came slowly and gradually, I never felt like I was sacrificing. I maintained a regular workout routine; chose whole foods over processed ones; modified portion sizes to match my nutritional needs; opted for a salad over a burger when I ate out; and ­requested one pump of syrup instead of two in my ­coffee drink.

It all took about 18 months, but I was committed. Consistency was more important than a quick fix.

By fall 2018, my blood pressure had normalized and I had lost 75 pounds.

My doctor said I could go off the meds — cold turkey. My blood pressure was stable when I saw him again a month later, and it’s remained stable ever since. Today, it’s in the range of 110–120/80, and I only see my doctor once a year for a wellness exam.

I now know what my body needs to be healthy.

Reaching and Keeping the Goal

My goals have changed since my blood pressure stabilized. In 2018, I joined Life Time, motivated by the amenities offered for children. Sarai was an active toddler by then, and I wanted her to learn how to have fun with fitness at a young age.

I started working with a personal trainer who created a routine that I can adjust as needed. I add more yoga classes during stressful times. I’ve also trained for and competed in a variety of races, including obstacle-course events and a half-marathon. I like the opportunity to modify my training and connect with other people in the fitness community.

I love being active with Sarai, who is now 10. We like to throw the football or shoot hoops together, and I’ll run alongside while she bikes.

Nutrition is an important part of our lives, and my husband and I have ­incorporated the phrase “nutrient-dense foods” into the family vocabulary. I hope my journey ­teaches Sarai she has the power to take control of her physical, mental, and spiritual health.

I’m also preparing to return to medical school. I hope to join an emerging field of physician nutrition specialists who work with patients with chronic disease. My dream is to run my own team and conduct research that incorporates nutrition. I want to help more patients learn how to improve their health outcomes through manageable lifestyle adjustments — like I was able to do for myself.

Michelle’s Top 3 Takeaways

1. Take control of your health. “I was waiting on doctors to cure me, until I realized I had to partner with my doctor and help myself,” says Michelle.

2. Take hypertension seriously. “What starts with obesity and hypertension becomes cardiac disease, then kidney disease, [and this can] lead to death. Try to prevent that early on.”

3. Make small changes over time. We often expect a quick snapback after birth, she notes. Huge change is not realistic. Reach the goal, then keep the goal.

Redefining Obesity https://experiencelife.lifetime.life/article/redefining-obesity/ https://experiencelife.lifetime.life/article/redefining-obesity/#view_comments Tue, 20 May 2025 12:56:42 +0000 https://experiencelife.lifetime.life/?post_type=article&p=115294 Rather than looking just at a person’s weight, some progressive healthcare providers are seeking to identify obesity by its metabolic effects.

The post Redefining Obesity appeared first on Experience Life.

In my late 30s, I was in the best shape of my life, cycling 20 to 30 miles daily, pumping iron regularly, and eating a plant-forward Mediterranean diet. Digestive issues I’d been dealing with had dissipated, and I was sleeping well after years of insomnia. I felt healthier than ever.

Imagine my surprise when my doctor told me I was overweight.

Many of us have faced this puzzling experience. Definitions of overweight and obesity often stem from misleading metrics such as the body mass index (BMI) my doctor used. These classifications can lead to a range of misunderstandings about what a higher body weight means for your health — not to mention the significant stress of being told you’re unhealthy solely because of your weight.

Given this confusion, some healthcare providers are turning to other metrics, including measurements of metabolic health, to determine whether a patient’s weight poses a health risk. They may deploy tests that measure stress hormones, glucose regulation, hormonal balance, thyroid and gut health, and inflammation, all of which affect how well your body converts food into energy and offer insight into your metabolic functioning.

The questions that follow examine why a metabolic framework for obesity might be a better starting point for determining the true status of your health.

Why do we gain weight?

While we typically assume weight gain is primarily about dietary choices — and they certainly can play a role — it can be influenced by a variety of factors. These include genetics, hormone dysregulation, sleep, stress, and certain medications.

Researchers are also investigating the role played by exposure to environmental toxins, sometimes called “obesogens.” These chemicals are often found in everyday items and include bisphenol A (BPA), which is employed in making plastics, and phthalates, endocrine disruptors commonly used in personal-care products. They can disrupt the body’s normal metabolic processes and endocrine function, promoting fat accumulation.

Excess weight can contribute to impaired cardiovascular function, joint stress, and breathing challenges, like sleep apnea. These physical impacts can be significant. Still, weight alone doesn’t provide a complete picture of a person’s overall metabolic health.

What’s wrong with relying on BMI as a measure of weight health?

Your body mass index is the measure of your weight in kilograms divided by the square of your height in meters. It’s widely used by healthcare providers to classify people as underweight, normal weight, overweight, or obese. (Learn more at “Beyond BMI: Why True Health Is About More Than What You Weigh.”)

“Physicians typically use BMI to measure a patient’s ‘weight health,’” explains Stewart Lonky, MD, in his book, Outsmarting Obesity: A Doctor Reveals Why We Gain Weight, Why It Matters, and What We Can Do About It.

Yet BMI is a blunt tool with significant limitations. It was first developed in the early 19th century — and updated by physiologist Ancel Keyes in 1972 — strictly as a research tool for measuring weight trends in populations. Neither of its creators were medical professionals, and they never intended BMI for medical use.

It was first developed in the early 19th century — and updated by physiologist Ancel Keyes in 1972 — strictly as a research tool for measuring weight trends in populations. Neither of its creators were medical professionals, and they never intended BMI for medical use.

The original study in which BMI was used didn’t include women and most of its participants were white men. This means its current status as a universal metric misdiagnoses a wide diversity of body types.

Most importantly, BMI reveals nothing about body composition. “The most significant drawback of BMI is its inability to differentiate between fat and muscle,” explains Lonky. “While it’s not accurate to say that muscle weighs more than fat, it is denser. This density is why a cubic inch of muscle weighs more than a cubic inch of fat.”

In a recent paper published in The Lancet Diabetes and Endocrinology, a commission of global experts argue that BMI-based definitions lead to overdiagnosis and underdiagnosis, labeling people as unhealthy when they aren’t and missing those who may be at risk despite a “normal” BMI. This can result in poorer health outcomes for everyone.

For example, a fit, muscular athlete might have a BMI over 30, qualifying them as obese strictly because of their weight-to-height ratio. On the other hand, someone with a “healthy” BMI of less than 25 might have metabolically active visceral fat (more on why that matters later) that puts them at risk for cardiovascular disease.

In neither case does their BMI explain anything about their actual health status.

Does the location of fat matter?

Where fat is stored may be more indicative of its risks than weight alone. “BMI tells you nothing about body composition or where you’re putting on weight,” explains holistic nurse practitioner Monique Class, MS, APRN-BC.

Visceral fat stored around vital organs in the abdomen appears to be particularly risky. Unlike subcutaneous fat, which is stored under the skin, visceral fat is sometimes described as “metabolically active” because it can produce hormones and inflammatory molecules. Fat around the midsection has been associated with systemic inflammation, insulin resistance, and cardiovascular risks.

Visceral fat can also be an indication of metabolic syndrome, a cluster of conditions — including high blood pressure, high blood triglycerides, low levels of HDL cholesterol, and insulin resistance — that occurs together. Metabolic syndrome increases a person’s risk of heart disease, stroke, and type 2 diabetes.  (Listen as Jim LaValle, RPh, CCN, explains the factors that contribute to insulin resistance, how to measure and monitor blood sugar, and the habits we can adopt to manage blood sugar effectively at “Breaking Insulin Resistance: Your Guide to Blood-Sugar Mastery.”)

What is “metabolic obesity”?

The global commission of experts involved in The Lancet Diabetes and Endocrinology report recommend defining obesity through clinical signs — such as tissue and organ alterations — that better capture when excess fat genuinely impacts health. This definition ensures a more precise identification of those in need of intervention and could lead to more effective treatment.

This approach acknowledges that caloric intake or physical-activity level are not the only factors influencing a person’s metabolic health. Chronic stress, sleep quality, thyroid health, hormone regulation, gut health, and genetics all play an important role. Understanding the root causes of disruptions in metabolic health would be the focus of any intervention.

By this definition, a thin person with metabolic syndrome could be classifiably obese while a heavier person may or may not. What matters most are factors like insulin regulation, blood pressure, and cardiovascular function.

By focusing on metabolic health, clinicians can identify and address issues such as hormonal imbalances and the role of visceral fat in driving inflammation and cardiovascular risks.

Are there other ways to classify higher weight and obesity?

Some researchers classify weight metabolically using these phenotypes:

  • Metabolically Unhealthy Normal Weight: People who have a BMI of between 18.5 and 24.9 but exhibit metabolic problems commonly associated with obesity or metabolic syndrome, such as insulin resistance and high blood pressure. Despite their lower weight, these individuals may face health risks due to underlying metabolic dysfunction.
  • Metabolically Unhealthy Obesity (MUO): Individuals with high weight and additional metabolic complications, such as high blood pressure, insulin resistance, and abnormal cholesterol levels. MUO is associated with higher risks for cardiovascular disease and type 2 diabetes.
  • Metabolically Healthy Obesity (MHO): People with a BMI over 30 without metabolic risk factors typically linked to obesity. Even if a person categorized as MHO has healthy metabolic markers, it’s important to manage those markers over time by remaining active and eating a quality diet. While MHO offers a lower immediate risk, studies have shown that up to 50 percent of individuals with MHO develop metabolic complications within a decade or so, driven by aging, weight gain, and declining insulin sensitivity.

Weight is only one aspect of overall metabolic health, so it’s important to recognize that the number on the scale tells the whole story. It makes perfect sense to question an obesity diagnosis, especially if it’s based on BMI, if you know you’re healthy, rested, and strong. The metabolic numbers are the ones that count.

Do I Need a Continuous Glucose Monitor? https://experiencelife.lifetime.life/article/do-i-need-a-continuous-glucose-monitor/ https://experiencelife.lifetime.life/article/do-i-need-a-continuous-glucose-monitor/#view_comments Tue, 04 Feb 2025 13:01:14 +0000 https://experiencelife.lifetime.life/?post_type=article&p=108780 Here are eight things to consider before deciding to track your blood sugar.

The post Do I Need a Continuous Glucose Monitor? appeared first on Experience Life.

]]>

If you’re into biohacking or personalized nutrition — or even if you’re not — you’ve probably heard about continuous glucose monitors (CGMs). These wafer-thin disks stick to the back of your arm, with a tiny wire inserted just below the skin to measure blood-sugar levels. They send minute-by-minute measurements to an app on your phone, which then sounds an alarm if your blood sugar spikes or dips.

CGMs can be useful for anyone who struggles with blood-sugar management — or who wonders whether they do. “We can use CGMs to get a bunch of data about how the body responds not just to how we eat but also to the intervals at which we feed ourselves, and the impact that physical activity and stress have on blood glucose,” says functional nutritionist Jesse Haas, MS, CNS, LN.

When you see and feel how a plate of pasta or a good morning workout affect your blood sugar, she adds, you can start to connect this information to other signals from your body. “That can be really empowering.”

As it happens, Haas is my nutritionist. I sought her out after discovering I had high blood sugar. That was a surprise — but also, it wasn’t.

I grew up in a family that loved food, especially carbs, and toast in particular. At family breakfasts, my grandfather kept a four-slot toaster and a loaf of country white on a bar cart at his elbow. Upon request, he’d send slices of piping hot toast flying down the table. (You want that butter to melt!)

As an adult, my professional life has revolved around writing about food. At home I’ve long maintained a solid Mediterranean diet, and I was a runner for years; for a time these healthy habits were enough to keep the effects of my dining life in check.

Then the day arrived when I got a note from my physician about my recent A1C blood test: It showed my average blood-sugar level in the prediabetic range. I needed to make some lifestyle changes, so I started using a CGM to help me identify which shifts made a helpful impact and which didn’t.

This worked well for me, but metabolic health is complex, and different bodies need different interventions. So, when considering whether to invest time, energy, and money into a CGM, it’s worth pausing to make sure you really need one. These are a few things I learned from using mine.

( 1 )

You may not know you have dysregulated blood sugar.

The Centers for Disease Control and Prevention (CDC) estimates that more than one in three adults have prediabetes — and that more than eight out of 10 don’t know it. According to Rita Rastogi Kalyani, MD, MHS, president-elect of medicine and science for the American Diabetes Association (ADA), there may be many reasons for this, including that most people probably aren’t getting a fasting glucose or A1C test on a regular basis as recommended. Even if they are, physicians don’t always flag a prediabetic number.

The blood-sugar range for prediabetes is 5.7 to 6.4 percent; diabetes is 6.5 percent or above. I had been hovering at 5.9 percent, but my own physician hadn’t mentioned it, possibly because my other health markers were good.

More than one in three adults have prediabetes — and that more than eight out of 10 don’t know it.

Yet prediabetes can be serious. Not only does it increase the likelihood of developing type 2 diabetes but the condition also raises the risk of heart disease, stroke, and nerve damage. Diabetes itself can lead to additional major complications, including kidney failure and blindness.

Among the risk factors for developing type 2 diabetes, according to Kalyani, are being higher weight, having a family history of the disease, and being in a high-risk group — African American, Latino, Native American, Asian American, or Pacific Islander. Hypertension and dyslipidemia (a metabolic disorder involving abnormally high or low levels of lipids in the blood) are other potential risk factors.

Women who have had gestational diabetes or have polycystic ovary syndrome are also at higher risk. The ADA recommends regular diabetes screenings if you’re over 35 whether you have any of these characteristics or not.

Because of my Asian American and Pacific Islander heritage, I’m not only genetically predisposed to develop type 2 diabetes but also at risk of developing it even with a lower body-mass index (BMI). The general rule is that diabetes risk increases at a BMI of 25 — but both the ADA and the CDC acknowledge that Asian Americans should screen at a BMI of 23. (It’s important to note that BMI itself is an unreliable measurement of body composition and health, which may be another reason to simply get screened no matter what.)

The signs of dysregulated blood sugar (also called dysglycemia) can be subtle. I often felt cranky or physically shaky between meals and tired after meals, but I assumed everyone did.

“The symptoms of dysglycemia are sneaky,” says Haas. “We don’t think about difficulty concentrating or making decisions as symptoms of low blood sugar. And we tend to associate the more cognitive, emotional, and mental symptoms — like anxiety, irritability, or depression — with something other than biochemistry, but that’s a part of it too.”

She adds that the restrictive eating patterns lauded by diet culture have also helped normalize the symptoms of low blood sugar. “This sets us up to have a really distorted expectation of what it feels like to be a human doing human life.”

( 2 )

A CGM can help you stay motivated.

A study from the CDC’s National Diabetes Prevention Program shows that lifestyle changes are about twice as successful as medications at lowering the risk of diabetes. Losing a little weight, changing your diet, and exercising regularly can all help the body regulate blood glucose. In fact, the study found that these changes can cut your diabetes risk in half.

My physician advised I get a minimum of 150 minutes of cardio activity a week; lose 5 to 7 percent of my body weight; consume fewer simple carbohydrates; and eat a diet rich in vegetables and fruits, fiber, and healthy fats, like avocado, nuts and seeds, olive oil, and fish.

I was already doing most of that, though I did need to cut back on the cake and toast. When I did, my A1C improved, but soon the desire for sugar crept back. I reverted to old eating habits, and after three months my A1C was back to 5.9 percent.

Lifestyle changes are about twice as successful as medications at lowering the risk of diabetes.

“A1C lab tests can be run at 90-day intervals to monitor blood-glucose averages, but a check-in every 90 days offers little accountability,” says Haas. “For people who are really interested in making a behavioral change, a CGM gives us real-time data.”

This internal feedback can also be a great source of “inspiration, motivation, and accountability,” she adds. The CGM reveals precise information about how specific choices affect your body, which can help you fine-tune the more general advice you might get from your physician or nutritionist.

Fitness and nutrition educator Mike T. Nelson, PhD, MSME, CSCS, CISSN, has given a lot of thought to CGMs and motivation. He says it can be hard to convince the athletes he works with that they have dysregulated blood sugar. They may not be feeling optimal, but when their lifestyle, sleep, and nutrition habits are all pretty good, they’re often convinced there’s no need for change.

“There’s something about looking at actual data, seeing their blood-glucose numbers — then they’re like, ‘Oh, there is something going on,’” he says.

That was true for me. I could not change my habits until I went to see an endocrinologist and got a prescription for a CGM, which provided me with real-time feedback on how my choices were affecting my body.

 

( 3 )

Getting a CGM is becoming easier.

CGMs are still used primarily by people with diabetes, and you need a prescription if you hope to get one covered by insurance (though not all insurance plans cover them). I was able to get two CGM sensors, a month’s worth, for a $75 copay. (If I hadn’t had insurance, the cost would have been double.)

Until recently it was tough to get a CGM without a prescription, but that’s changing. A growing number of digital health companies, like Nutrisense, Levels, and Zoe, are pairing CGMs with phone apps to monitor blood-glucose levels, track nutrients, and offer personalized nutritional feedback. In addition, Dexcom and Abbott, two of the primary CGM manufacturers in the United States, recently gained FDA approval to launch over-the-counter versions of their glucose monitors.

For best results, partner with a professional and set goals.

Nelson suggests setting parameters for your CGM use. The first is to be sure to work with a health professional. This can help you put the feedback you get into a larger context. “You need someone to help you figure it out,” he says. “Even when people are trying to do their best, they can just get hung up on a number — a number that’s not always good or always bad.”

The second parameter: Know your goals. “Figure out what you want to learn from this data ahead of time,” advises Nelson. “You need a hypothesis and some experiments so that you can learn from it.”

Know your goals. “Figure out what you want to learn from this data ahead of time.”

The initial revelations from my own CGM allowed me — with help from my endocrinologist — to understand how to begin lowering my A1C: Cut down on simple carbohydrates; increase the fiber, fat, and protein in my meals; and get more regular exercise.

Then I started working with Haas for nutritional fine-tuning. She helped me address the subtler questions, like, Why am I having low blood sugar in the morning? Can I have some grains in my diet? What should I do if I’m experiencing high blood sugar over a longer term? I would have been pretty lost without this guidance.

The third parameter Nelson suggests: Be ready to change. Once you establish how you need to adjust your diet and lifestyle, be ready to do it. Your partnership with a health professional can provide accountability.

 

( 5 )

CGMs can stoke anxiety.

While some of us find the real-time feedback of a CGM motivating in a healthy way, that’s not true for everyone. “There’s a caution for folks who are inclined to get more anxious when they’re getting a lot of input,” Haas explains.

She suggests anyone with disordered eating may want to steer clear of a CGM, especially those inclined to extreme food restriction. “It’s not all good, right?” she adds. “That’s part of personalized healthcare — reflecting and self-selecting.”

Anxiety around blood-glucose numbers may also provoke people to make sweeping nutrition decisions — even when everything else is fine. Nelson has watched clients adopt a ketogenic protocol after seeing borderline high blood sugar on their CGM, which could easily end up being an overcorrection.

“I get worried when people take data out of context,” he says. “It happens with heart-rate variability, it happens with sleep data, it happens with a CGM. People are so into optimizing that they’re worrying about stuff they just should not be worried about.”

 

( 6 )

Monitoring your blood sugar can teach you a lot about what’s going on in your body.

Metabolic health influences all the body’s systems, so blood-sugar regulation has a broad impact on well-being. These are just a few examples of what blood-sugar measurements can reveal.

• Stress: When we’re worried, triggered, or in a stressful situation, the body releases cortisol, which raises blood glucose, Haas explains.

• Sleep: There are many potential causes for poor sleep, and a CGM can reveal if blood sugar is what’s keeping you awake. Our body’s natural circadian rhythms raise blood-sugar levels at night, a surge called the dawn effect. For people with dysglycemia, this surge tends to affect sleep quality.

The reverse is also true. “It’s not just that dysglycemia disrupts sleep,” says Haas. “Poor sleep can also disrupt your blood sugar.”

• Weight management: A CGM can show how different foods affect our blood sugar. This feedback can help us adjust our diet in favor of greater blood-sugar regulation. “We’re telling our pancreas, ‘Hey, we’re good. We’re going to reduce the glucose burden so that you’re not exhausted pumping out insulin.’ And that’s going to support weight balance,” Haas explains.

• Exercise and athletic performance: CGMs can show us how exercise affects our blood sugar, including how quickly we’re recovering from strenuous workouts. They can also show you the positive impact of a postmeal walk in real time.

Unless you have diabetes, a CGM is a place to visit, not to live.

Experts agree that for most people who don’t have diabetes, a CGM is best used as a short-term intervention. Nelson recommends wearing a CGM for two weeks to establish a baseline. He believes it’s paramount to avoid data overwhelm, and counsels his fitness clients not to look at their data for the first week. He does this to prevent them from making dramatic changes on their own without his input.

After reviewing the data from the first week, Nelson and his clients decide on three or four areas of focus for the next round. “By the end of two weeks, they have some actionable data and a couple things that we’ve found that are really going to move the needle.”

Haas aims for three months with a CGM to establish a baseline. “Ninety days is enough time to focus on virtually anything — and to really create a new habit.”

Beyond that, she suggests using the CGM for short periods a couple of times a year to support habit maintenance. A CGM can also be useful anytime you’re undergoing a notable transition, such as perimenopause, during which the body’s needs are likely to change.

“[It’s good for] any big life change where stress is high and relearning self-care is really critical,” she advises.

A CGM can give you a better understanding of what your body needs.

For me, the CGM was the equivalent of a front-row seat at the carb-tolerance show: I learned that rutabagas don’t work for me but lentils do. That I can eat brown rice if it’s had a night in the fridge developing resistant starches. Not so with sweet potatoes: Even a wee dollop is a problem.

There were other great lessons, too, like everything goes better if I load up on protein and fiber; I need a small snack before bed; and, wow, does public speaking give me a spike — even though I kind of dig talking to a crowd.

Most importantly, the CGM plus some excellent healthcare advice helped me figure out how to keep my blood sugar fairly balanced — and I got my A1C down to 5.4 percent. My endocrinologist tells me that if I keep it down, I’m less likely to develop type 2 diabetes. That’s life-changing medicine.

“That’s the beautiful thing about a CGM,” says Nelson. “You can make huge changes to your data with simple interventions. There aren’t a lot of other measurements in the body that you can push around that much. And you can see a pretty big change, sometimes in short order.”
