I Got a Prediabetes Diagnosis Last Year—Here’s What No One Told Me About What Prediabetes Actually Is

I still remember sitting in my doctor’s office last March, staring at my annual lab results like they were written in a foreign language. I was 37 at the time, worked a 9-to-5 marketing job that kept me glued to my desk, grabbed takeout 4 nights a week, and hadn’t stepped foot in a gym in 2 years. I’d gone to the checkup because I was constantly exhausted, had to get up 2 or 3 times a night to pee, and was dealing with weird sugar cravings that hit so hard I’d eat a whole candy bar at my desk at 3pm. I thought it was just burnout from our busy launch season. Then my doctor said the word that stopped me cold: prediabetes.

I had no idea what prediabetes even was, back then. I thought diabetes was something only people twice my age got, or people who ate nothing but sugar all day. I had no clue I was already on the path to it—until I wasn’t. Over the last year, I’ve learned more about prediabetes than I ever thought I would, reversed my diagnosis, and picked up a ton of hard-earned lessons along the way. Today I’m sharing everything I wish someone had told me when I first got that diagnosis.

What Is Prediabetes, Exactly? The Science Broken Down Simply

To put it plainly, when you eat, your body breaks down food into glucose (sugar) that circulates in your blood. Insulin, a hormone made by your pancreas, helps move that glucose into your cells to use for energy. When you have prediabetes, your body starts to become resistant to insulin, so glucose builds up in your blood instead of going into your cells. It’s not high enough to be diagnosed as type 2 diabetes yet, but it’s a clear warning sign that your body is struggling to process sugar the way it should.

The official diagnostic numbers from the American Diabetes Association (ADA) are:

My results? Fasting glucose of 112 mg/dL, A1c of 5.9%. I was squarely in the prediabetes range, and my doctor told me if I didn’t make changes, I’d likely be diagnosed with type 2 diabetes within 5 years. That scared me enough to start taking it seriously—but I messed up a lot before I figured out what actually worked.

My Biggest Prediabetes Missteps (The Mistakes That Almost Pushed Me to Full Diabetes)

I made almost every common mistake in the book in my first 3 months after diagnosis, and I want to save you from making the same ones:

  1. I ignored symptoms for 6 months before getting tested. The fatigue, frequent nighttime bathroom trips, and intense sugar cravings I was dealing with are all early signs of prediabetes, but I wrote them off as work stress, even when my mom (who has type 2 diabetes) urged me to get tested. In those 6 months, my A1c went up 0.3% without me even noticing.
  2. I cut all carbs cold turkey, then binged badly. The day after my diagnosis, I threw out all bread, pasta, and fruit in my house and ate only chicken and salad for 2 days. By day 3, I was so irritable and craving sugar so badly that I ate an entire box of donuts on my way home from work. My blood sugar an hour later was 182 mg/dL—way higher than it had ever been before. I felt like a failure and almost gave up entirely.
  3. I thought 10 minutes of walking a week was enough. I’d walk around the block on Sunday afternoons and pat myself on the back, but I was still sitting at my desk for 8 hours straight every other day of the week. When I finally got my 3-month follow-up test, my A1c hadn’t dropped at all.
  4. I avoided follow-up tests out of fear. I ignored my doctor’s calls for 2 weeks because I was convinced my numbers had gotten worse and I’d have to start taking medication. I only went in when my doctor sent me a message saying we could work through whatever the results were, no judgment.

The 5-Step Routine That Brought My Blood Sugar Back to Normal in 8 Months

After my failed first 3 months, I worked with a dietitian to build a sustainable routine that didn’t feel like punishment. 8 months later, my A1c dropped to 5.3% (well within the normal range) and I’m no longer classified as having prediabetes. These are the steps that worked for me, backed by peer-reviewed research:

  1. Track your numbers consistently first. I bought a $25 over-the-counter A1c test kit and a $15 basic glucose meter so I could check my levels at home instead of waiting for doctor’s appointments. I logged my fasting glucose twice a week and post-meal glucose once a week in a free app, which helped me see exactly what foods spiked my blood sugar (for me, white rice and regular soda were the worst offenders) and what kept it stable.
  2. Swap 50% of refined carbs for whole grains and non-starchy veggies, don’t cut carbs entirely. I stopped eating white bread, white rice, and regular pasta, and swapped half those servings for quinoa, brown rice, whole wheat pasta, or veggies like broccoli, spinach, and bell peppers. I still eat carbs—last night I had a whole wheat taco with black beans and corn, plus a small bowl of ice cream for dessert. A 2022 JAMA study found that people with prediabetes who made this swap reduced their risk of progressing to type 2 diabetes by 34% over 2 years.
  3. Add 10 minutes of light movement right after every meal. This was the single most effective change I made. A 2023 ADA study found that 10-minute walks after breakfast, lunch, and dinner reduce post-meal blood sugar spikes by up to 22% for people with prediabetes, more effectively than a single 30-minute walk once a day. I walk around the block after breakfast, walk up and down the office stairs 5 times after lunch, and walk my golden retriever after dinner. It adds up to 30 minutes of movement a day with no gym membership required.
  4. Cut added sugars by 90%, don’t eliminate them entirely. I used to drink 2 regular sodas a day plus a sweetened iced coffee, which added up to almost 80 grams of added sugar a day—way more than the ADA’s recommendation of 36 grams a day for men, 25 for women. Now I drink sparkling water with lemon instead of soda and unsweetened iced coffee with a splash of oat milk. I still have soda or cake at birthday parties, I just don’t have those things every day.
  5. Work with a registered dietitian, not TikTok hacks. I saw dozens of TikTok videos claiming apple cider vinegar shots or expensive supplements could reverse prediabetes, almost none of which have scientific backing. My health insurance covered 3 free sessions with a dietitian, who even gave me a recipe for healthy enchiladas (my favorite food) that fit my new eating pattern.

Common Questions (FAQ) About Prediabetes

Q: Is prediabetes reversible?

A: Absolutely. The CDC estimates that up to 70% of people with prediabetes can avoid progressing to type 2 diabetes entirely if they make consistent lifestyle changes, and many can bring their blood sugar levels back to the normal range, like I did. The key is catching it early and making sustainable changes, not crash diets or extreme workouts you can’t keep up with long term.

Q: Do I need to take medication if I have prediabetes?

A: Most people don’t. The ADA recommends lifestyle changes as the first line of treatment for prediabetes. Medication like metformin is only prescribed for people at very high risk of progressing to type 2 diabetes—for example, people with an A1c over 6%, or people with other risk factors like high blood pressure or a family history of type 2 diabetes. Always talk to your doctor about what treatment plan is right for you.

Q: Can I still eat sugar and carbs if I have prediabetes?

A: Yes! You don’t have to cut out all sugar or carbs entirely. The key is to limit added sugars (like the sugar in soda, candy, and pastries) to less than 10% of your daily calories, and choose whole, unrefined carbs (like whole grains, fruit, and starchy veggies) over refined carbs (like white bread, white rice, and pastries) most of the time. I still eat a chocolate chip cookie once a week, and my blood sugar stays perfectly stable.

Q: How do I know if I have prediabetes?

A: The only way to know for sure is to get a blood test, because most people with prediabetes have no obvious symptoms. The CDC recommends all adults over 45 get tested for prediabetes at least once every 3 years, and adults over 18 who are overweight or obese and have at least one other risk factor (like a family history of diabetes, high blood pressure, high cholesterol, or a history of gestational diabetes) get tested regularly, even if you feel fine.
