Why Weight Loss Feels Impossible With Prediabetes (And What to Fix First)

Your doctor tells you that losing 15 pounds will help your blood sugar.
That may be true.
But what many people are not told is why weight loss suddenly feels so impossible once insulin resistance enters the picture.
You might be doing everything you have always heard works.
Eating less. Exercising more. Trying to stay disciplined.
And yet the scale barely moves.
If that sounds familiar, you are not imagining it. There is a real physiological reason this happens. The issue is often insulin. I want to show you exactly why.
📖 A Tale of Two Metabolisms
Let me tell you a quick story about two people.
John is 34.
His BMI is 27. His fasting glucose is normal. His A1c is normal. He simply wants to lose about 15 pounds.
So he follows the typical advice.
He cuts about 500 calories per day and starts taking an exercise class three times per week.
Twelve weeks later he is down 15 pounds.
Pretty straightforward.
Now let’s look at Sarah.
Sarah is 54.
Her BMI is also 27. She also wants to lose 15 pounds.
But Sarah’s fasting glucose is 118 and her A1c is 6.0. She has been diagnosed with prediabetes and insulin resistance.
Her waist to hip ratio is elevated, which suggests she has some visceral fat accumulation.
Sarah follows the exact same plan as John.
She cuts 500 calories per day.
She runs five miles three times per week.
But the scale does not move.
So she tries harder. She signs up for a 5am bootcamp class.
Instead of losing weight she becomes more tired, more hungry, and more discouraged.
So what is the difference between these two situations?
Most people assume the answer is age.
They assume Sarah’s metabolism has slowed down.
But that is usually not the real explanation. The difference is insulin.
🧬 The Hormone That Controls Fat Storage
Insulin is one of the most important hormones in your body. It is an anabolic hormone, which simply means it helps build and store things.
Insulin helps your body:
store nutrients
repair tissues
build muscle
create fat stores for energy
This is completely normal and necessary for survival. However, insulin also promotes a process called lipogenesis, which is the creation of fat. When insulin levels are elevated for long periods of time, your body receives a very specific signal.
➡️ Store energy.
➡️ Protect stored fat.
➡️ Avoid releasing energy.
This is why insulin resistance changes the entire weight loss equation. If insulin is chronically elevated, the body is essentially locked in storage mode. And when your body is in storage mode, losing fat becomes much more difficult.
📆 Insulin Often Rises Years Before Blood Sugar
Here is something most people do not realize. Insulin often rises years before blood sugar rises. By the time someone sees fasting glucose numbers like 110, 115, or 118, insulin may have been elevated for a very long time. This early stage is sometimes informally called pre-prediabetes.
Blood sugar may still appear relatively normal for a while because insulin is working overtime to keep glucose controlled. But that comes at a cost. Over time the body becomes less sensitive to insulin. The pancreas produces more and more of it. And that persistent elevation in insulin makes fat loss increasingly difficult.
So when Sarah tries to lose weight, her body is receiving a constant signal:
Store. Protect. Conserve.
That changes everything.
💥 Why Cutting Calories Can Backfire
One of the most common things I hear from clients is this:
"I have cut my calories ridiculously low and I still cannot lose weight."
Here is why that can happen. Calories do matter for weight loss. But calories are not the only thing that influences metabolism. Macronutrients influence insulin far more directly than calories alone.
If insulin is already elevated and someone aggressively cuts calories, the body can interpret that as a stress signal. When that happens several things occur:
➡️ Cortisol rises.
➡️ Hunger hormones increase.
➡️ Metabolic rate may adapt downward.
This process is called adaptive thermogenesis, and it is sometimes referred to as starvation mode.
If someone drops to 1,000 calories per day while insulin is elevated, the body does not think: Great. Let’s burn fat.
Instead it thinks:
We are under threat. Conserve energy.
On top of that, blood sugar dips may trigger rebound hunger later in the day. That can lead to overeating and intense cravings. And then people blame themselves for lacking discipline. But physiologically their body was simply trying to survive.
🍩 Why Cravings Feel So Powerful
Another very common experience involves cravings. You walk past the pantry. You were not even hungry five minutes ago. But suddenly you want chocolate. Not one square. A handful.
This is often a sign of dysregulated hunger signaling. When insulin and blood sugar fluctuate throughout the day, it can disrupt several key hormones that regulate appetite.
These include:
Ghrelin, which signals hunger.
Leptin, which signals fullness.
GLP-1, which helps regulate appetite and insulin response.
When these hormones become dysregulated, hunger signals become confusing and exaggerated. That is why willpower is not a reliable long term solution. You cannot out discipline unstable hormone signals.
🍠 The Healthy Food Trap
Another scenario I hear frequently is this:
"I am eating healthy and exercising regularly but I still cannot lose weight."
The issue here is that healthy food does not always mean metabolically neutral food. For someone with insulin resistance, certain carbohydrate rich foods can still create significant glucose and insulin responses.
Examples include foods like:
Sweet potatoes
Bananas
Oatmeal
These foods are nutritious. But in someone with insulin resistance they may still cause repeated blood sugar spikes throughout the day. That keeps insulin elevated. And elevated insulin keeps the body in storage mode.
Exercise strategy also matters. Exercise is incredibly valuable for overall health. But extremely intense workouts can sometimes increase stress hormones. If someone is doing intense circuit training or high intensity workouts early in the morning, cortisol and blood sugar may temporarily rise. That does not mean exercise is bad. It simply means the strategy needs to match the metabolic situation.
⏭️ Why Weight Loss Should Happen in Two Phases
One of the most helpful ways to think about weight loss with insulin resistance is to recognize that there are two different physiological phases.
Trying to skip the first phase is where many people run into trouble.
Phase 1: Metabolic Stability
The goal of the first phase is to stabilize blood sugar and insulin signaling. During this phase several positive changes typically occur. Fasting glucose begins to normalize. A1c gradually moves below 5.7. Fasting insulin ideally falls below 7. Cravings become less intense. Energy becomes more stable throughout the day.
Some people do lose weight during this phase. But that is not the primary goal. The primary goal is metabolic stability.
Phase 2: Intentional Fat Loss
Once insulin and blood sugar are more stable, the body becomes much more receptive to fat loss. At this stage: Calorie adjustments become more effective. Exercise produces better results. Fat loss becomes easier to maintain.
In other words, once the physiology is working with you instead of against you, the traditional strategies start working again.
💡 The Real Reason Weight Loss Feels So Impossible
If you have been frustrated by stubborn weight loss, it is important to understand something. This is not about willpower. And it is not about something being wrong with you. It is about physiology.
When insulin is elevated and the body is in storage mode, losing weight can feel like pushing uphill. But when insulin signaling improves, the body becomes far more willing to release stored fat. That is why focusing on blood sugar stability first often produces much better long term results.
🏁 Fix the Physiology First
If you suspect insulin resistance may be affecting your metabolism, the most helpful first step is stabilizing blood sugar patterns. Once that foundation is in place, fat loss becomes dramatically easier.
If you would like help getting started, I created a free resource that walks you through the first steps. You can download my Free 7 Day Blood Sugar Balance Plan using the link below. It will help you begin addressing the physiology that makes weight loss possible. Because when your metabolism feels safe, your body is far more willing to let go of excess weight.
