I’m an Endocrinologist Who Reversed My Own Insulin Resistance — Here’s Exactly What I Did in 90 Days

As an endocrinologist, Dr. Thomas spends his days telling patients how to manage their blood sugar. But then his own lab results revealed he was heading straight for type 2 diabetes.

You are likely feeling exhausted. You might be unable to lose weight despite dieting. You feel overwhelmed by conflicting nutritional advice. You just want your health back.

This guide reveals the exact 90 day protocol Dr. Thomas used to reclaim his body. He normalized his fasting glucose. He dropped his HOMA IR score. He regained his energy without starving himself.

Dr. Thomas got his bloodwork back on a Tuesday. He stared at a highly elevated HOMA IR score in total shock. This is a reliable medical calculation using fasting glucose and fasting insulin to determine resistance levels.

He felt hypocritical giving advice he completely failed to follow. His signs of prediabetes were loud and clear. He had terrible afternoon energy crashes. He carried stubborn visceral fat around his waist. Doctors are clearly not immune to modern lifestyle stress.

You might be experiencing these exact same issues right now. You are definitely not alone.

According to the NIDDK, roughly 97.6 million adults in the US have prediabetes. A 2025 cohort study published in JMIR Medical Informatics shows alarming data. Individuals in the high risk insulin resistance group are over 5 times more likely to develop diabetes than those in the low risk group.

But a diagnosis is not a life sentence. It is a pivot point. You can improve your fasting insulin level.

Step 1: Clothing Your Carbohydrates For A Good Insulin Resistance Diet Plan

Dr. Thomas learned to stop eating naked carbs. A naked carb is something like eating a plain bagel by itself.

When you eat a naked carb, your body suffers a rapid glucose spike. This forces a massive insulin surge. Then you experience a hard crash and intense cravings. Clothed carbs fix this entire problem.

You must dress your carbohydrates in healthy fats or protein. This delays gastric emptying. Gastric emptying is simply the medical term for how fast food leaves your stomach.

You need to focus on your glycemic load instead of the outdated glycemic index. Glycemic load measures how much a food will actually raise your blood sugar based on portion size.

An effective insulin resistance diet plan works best when you emphasize 50 grams of daily fiber. This naturally balances your blood sugar.

For example, never eat an apple alone. Pair a green apple with a handful of almonds.

Top materials to clothe your carbs:

Fueling Satiety

Macronutrient Synergy

Cellular Nourishment

Incorporate healthy fats like avocados or nuts to promote long-lasting satiety, delay gastric emptying, and support brain health.

Muscle Preservation

Prioritize lean proteins like eggs or chicken to preserve lean muscle mass, increase thermogenesis, and keep hunger hormones in check.

Digestive Regulation

Add plenty of soluble fiber like black beans or oats to slow down digestion, feed your gut microbiome, and stabilize blood sugar levels.

Step 2: Continuous Glucose Monitor Benefits For Real Time Blood Sugar Tracking

Finger pricks are completely outdated for true metabolic repair. Dr. Thomas started using a CGM as his personal metabolic dashboard.

You get amazing continuous glucose monitor benefits when you can see your data constantly. Real time blood sugar tracking changed his entire relationship with food. One morning he ate a bowl of plain oatmeal.

It spiked his glucose unexpectedly. This proved that nutrition is highly individualized for every single person.

Seeing your spikes within 30 minutes of eating specific foods changes your behavior instantly. You discover hidden triggers. Poor sleep and stress will ruin your numbers just as fast as candy.

Modern tools make this incredibly easy in 2026.

  • The Dexcom G7 features a 15.5 day wear time and a fast 30 minute warmup.
  • The Abbott FreeStyle Libre 3 Plus streams data discreetly for 15 full days.

Ask your doctor for a prescription. You can also look into an over the counter wellness CGM program.

Step 3: Building A Glucose Sink With Resistance Training

Endless treadmill running is not the best way to lose weight. Dr. Thomas realized cardio alone is not enough to reverse insulin resistance.

Skeletal muscle is your body’s largest consumer of glucose. Think of your muscles as a giant sink. When you build muscle, you expand your body’s tank to store glucose. Muscle absorbs glucose from the blood without needing insulin to open the cellular doors.

This means lifting weights increases your muscle cell insulin sensitivity. This biological magic happens completely independent of the hormone itself. Resistance training builds the sink you desperately need.

Start with a simple and achievable regimen:

Strength Baseline

The Foundation Protocol

Consistent Frequency

Commit to 3 days a week to establish a reliable habit while allowing your muscles adequate time to recover between sessions.

Focused Duration

Do 30 minutes of strength training per session to maximize efficiency, keeping your heart rate up without leading to burnout.

Accessible Mechanics

Begin with basic bodyweight squats or simple resistance bands to master foundational movement patterns safely before adding heavy loads.

Step 4: Lower Fasting Blood Sugar By Lowering Cortisol

You absolutely cannot out diet chronic stress. There is a powerful physiological link between cortisol and insulin.

When you are stressed, your body enters a constant fight or flight mode. The stress hormone cortisol acts like an alarm system. It signals your liver to dump emergency sugar directly into your bloodstream. This completely ruins your fasting glucose numbers.

Chronic stress can keep your HOMA IR levels elevated even if you eat a perfect diet. Dr. Thomas had to fix his daily tension to lower fasting blood sugar. He needed metabolic rest.

Use these simple interventions to sleep better and lower stress:

  • Take a gentle 15 minute walk right after dinner.
  • Practice 16 to 8 intermittent fasting to let your digestion rest.
  • Create a digital sunset by turning off screens an hour before bed.

Dr. Thomas noticed a deeply frustrating pattern. His morning blood sugar stayed high even after a perfect day of eating.

Poor sleep makes your cells reject insulin. Just one night of bad sleep creates instant resistance the very next day. Your body releases extra stress hormones to force you to stay awake. These hormones block your insulin from doing its job correctly.

Fixing your sleep schedule fixes those stubborn morning numbers.

  • Keep your bedroom cool and completely dark.
  • Go to bed at the exact same time every single night.
  • Stop drinking coffee by noon so your brain can actually rest.

6. 3 Ways To Fix Hidden Liquid Sugars In Your Diet

Liquid sugar causes the absolute fastest glucose spikes. It hits your liver instantly because there is zero solid food to slow it down.

Dr. Thomas found that supposedly healthy fruit juices were keeping his HOMA IR dangerously high. You must stop drinking your calories to heal your metabolism.

Drinking plenty of plain water actually helps dilute the sugar currently in your blood. Your body flushes out excess glucose through your kidneys when you stay fully hydrated.

Use these three rules to clean up your daily drinks.

Metabolic Hydration

Morning Health Protocols

Whole Food Fiber

Swap your morning juice for a whole orange and a large glass of water. The intact fiber dramatically slows fructose absorption, preventing glucose spikes.

Electrolyte Balance

Add a small pinch of sea salt to your water. The natural trace minerals facilitate better cellular hydration rather than the water just flushing right through you.

Acetic Acid Primer

Drink one tablespoon of apple cider vinegar mixed in water right before your biggest meal to improve insulin sensitivity and support stomach acid production.
