Why Eating Too Little Can Make Insulin Resistance Worse-And how nourishing your body properly can help heal your metabolism
If you’ve been struggling with insulin resistance, PCOS, stubborn weight gain, energy crashes, or migraines, chances are you’ve been told some version of this advice:
“Just eat less.”
For years, I thought that was the answer too.
I worked out consistently. I ate what most people would consider “healthy.” I tried to be disciplined. But despite all of that, my body still felt off. I was exhausted, inflamed, constantly hungry, struggling with weight gain that didn’t make sense, and dealing with migraines that affected my daily life.
Eventually, I discovered I was dealing with insulin resistance and low-grade PCOS — and it completely changed the way I viewed nutrition.
One of the biggest things I learned?
Undereating can actually make insulin resistance worse.
Your Body Needs Fuel to Function Properly
A lot of women with insulin resistance fall into a cycle of:
Restricting calories
Skipping meals
Under-eating protein
Overdoing cardio
Constantly trying to “burn off” food
But when we chronically underfuel ourselves, our bodies begin to perceive stress and scarcity.
That can lead to:
Increased cortisol (stress hormone)
Muscle loss
Slower metabolism
More blood sugar instability
Increased cravings and binge cycles
Poor energy production
Greater insulin resistance over time
Our cells become less efficient, not more.
Insulin Resistance Is About More Than Sugar
Insulin is a hormone that helps move glucose (sugar) from your bloodstream into your cells where it can be used for energy.
When your cells become resistant to insulin, your body has to produce more and more insulin to get the same job done.
Over time, this can contribute to:
Fatigue
Weight gain
Brain fog
Hormonal imbalance
PCOS symptoms
Inflammation
Cravings
Headaches and migraines
One of the best ways to improve insulin sensitivity is by supporting the body properly — not starving it.
Why Protein and Muscle Matter So Much
Muscle is incredibly important for insulin sensitivity.
The more lean muscle mass we have, the better our bodies are at utilizing glucose efficiently. Muscle essentially acts like a sponge for glucose, helping improve blood sugar regulation and metabolic health.
This is one reason why strength training and adequate protein intake can be so powerful for women with insulin resistance.
Instead of focusing only on eating less, we should also focus on:
Eating enough protein
Building muscle
Balancing meals
Supporting blood sugar stability
Nourishing our bodies consistently
Protein also helps:
Keep us fuller longer
Stabilize energy
Reduce cravings
Support hormone production
Improve recovery and metabolism
Don’t Forget Micronutrients
Macronutrients (protein, fats, and carbohydrates) matter — but micronutrients matter too.
When we overly restrict food, we often miss out on important vitamins and minerals that support:
Hormone health
Blood sugar regulation
Nervous system function
Energy production
Recovery and inflammation
Foods rich in nutrients like magnesium, potassium, omega-3s, B vitamins, and antioxidants can make a huge difference in how we feel day to day.
My Experience with Lower Carb Eating
One thing that has personally helped me tremendously has been lowering my carbohydrate intake — not in an extreme, fear-based way, but in a balanced and intentional way.
I noticed improvements in:
My A1C levels
My fasting insulin levels
Energy stability
Hunger cues
Migraine frequency
For me, lowering carbs while prioritizing protein, healthy fats, fiber, and nutrient-dense foods helped my body feel calmer and more regulated.
And importantly:
I still eat enough.
That part matters.
Low carb does not have to mean starving yourself. It can simply mean being more intentional about choosing foods that help your blood sugar stay stable and your body feel nourished.
Focus on Supporting Your Body — Not Punishing It
Healing insulin resistance isn’t about perfection.
It’s about learning how to work with your body instead of constantly fighting against it.
Sometimes that means:
Eating more consistently
Prioritizing protein
Strength training
Managing stress
Sleeping better
Choosing lower glycemic foods
Nourishing your body instead of depriving it
Your body is not broken. It’s asking for support.
Low Carb Cauliflower Cheddar “Buns” or Taco Shells
These are one of my favorite low carb alternatives for buns, wraps, or taco shells. They’re cheesy, crispy, filling, and surprisingly versatile!
Ingredients
2 cups cauliflower florets
1 egg or 2 egg whites
1/2 tsp garlic powder
1/4 tsp salt
2 1/4 cups cheddar cheese
Instructions
Preheat oven to 400°F.
Line two baking sheets with parchment paper.
Add cauliflower florets to a food processor and pulse until finely grated with no large pieces remaining.
Add the remaining ingredients and pulse until fully combined.
Scoop about 3 tablespoons of mixture onto the baking sheet.
Flatten into thin, round circles (about 1/8–1/4 inch thick depending on preference).
Repeat with remaining mixture.
Bake for 15–20 minutes until golden brown, flipping halfway through.
These work great for:
Burgers
Sandwiches
Taco shells
Breakfast wraps
Pizza-style flatbreads

Final Thoughts
If you’re struggling with insulin resistance, please know this:
You do not need to earn your food.
You do not need to starve yourself to heal your metabolism.
And you are not failing if extreme restriction isn’t working.
Sometimes the answer is actually learning how to nourish your body better — with enough protein, enough nutrients, enough support, and enough consistency to allow your body to finally feel safe again.
