Alright, let’s dive into a topic that's both hefty and deeply personal: insulin resistance and obesity. I’ll keep it conversational, but be prepared for some scientific terms, with links to studies for those interested in diving deeper. This is a significant reason why I started Fitness Beast, and it ties into the type 1 diabetes angle I explored in my previous blog.
Insulin Resistance and Obesity: Key Insights
Let’s start with a crucial quote:
“The two main factors that seem to contribute to insulin resistance are excess body fat, especially around your belly, and a lack of physical activity.” [Read more]
When I was diagnosed with type 1 diabetes at age 11, my weight was already a significant concern. At that time, my diabetes management was complicated by the higher insulin requirements due to my elevated body weight. I was prescribed 80 units of long-acting insulin—Humulin N, if my memory serves me right. My rapid insulin dosage was adjusted according to a sliding scale, reflecting the necessity for precise control. This experience highlights a common issue: excess body weight can lead to increased insulin needs and more intensive monitoring, making diabetes management more complex.
The Cleveland Clinic and the American Diabetes Association emphasize that “being sedentary, overweight, or obese increases the risk for insulin resistance.” [Source] This well-documented link shows that excess body fat and a lack of physical activity are significant contributors to insulin resistance. Studies consistently show that higher body fat and lower activity levels impair insulin function, leading to greater insulin resistance. Reflecting on my situation nearly three decades ago, my higher BMI resulted in significantly elevated insulin needs. Now, at 39, I've seen a marked improvement: my long-acting insulin dosage has decreased from 80 units to 24 units, and my rapid insulin needs have dropped from approximately 3 or 4 units per 30 grams of carbohydrates to about 2 units per 45 grams. This improvement underscores the benefits of weight management and lifestyle changes in enhancing insulin sensitivity and achieving better diabetes control.
This reduction in insulin requirements reflects a broader trend observed in many individuals as they manage their body weight and lifestyle more effectively. Maintaining a healthy weight and staying active are crucial for reducing insulin resistance and managing diabetes. As noted by The Cleveland Clinic and the American Diabetes Association, "excess body weight and a sedentary lifestyle increase the risk of insulin resistance."
Now, the one thing you need to remember is that insulin resistance is not limited to diabetics, regardless of whether you're a type 1 like me (having been born with it), or you're suffering from type 2, which is generally late-onset diabetes that is reversible, or you could be a non-diabetic, on your way to becoming one.
The Vicious Cycle of Insulin Resistance and Weight Gain
This is where things get a little tricky: the vicious cycle of insulin resistance and weight gain. Unlike most hormones, insulin has a limit. Your pancreas can only produce so much insulin before it reaches its capacity, contributing to the development of type 2 diabetes.
When your body accumulates excess fat or adipose tissue, it not only hinders effective insulin use but also leads your pancreas to produce more insulin to handle the higher demand. However, figuring out the exact balance of what you should eat versus how much insulin your body needs is complex. This balance can vary greatly depending on your body type, metabolic rate, and the types of foods you consume. And as far as I know, there is no exact formula that is available to determine that, as I'm pretty sure, as mentioned just before, it can be affected by many, many things.
As insulin resistance worsens, your body struggles to produce enough insulin to perform its primary role—transporting glucose to your liver and muscle cells. Consequently, glucose ends up being stored as fat. This leads to further weight gain, which exacerbates insulin resistance, creating a relentless cycle of gaining weight and worsening insulin resistance. It’s a challenging situation that creates that vicious cycle mentioned in the header, and that many people struggle with daily.
The Impact of Unstable Blood Sugars on Hunger and Eating Habits
The situation worsens when considering how unstable blood sugar levels can affect your hunger and food choices. Foods that disrupt blood sugar stability are often not very satisfying. High-sugar, low-fiber foods can leave you feeling hungrier sooner, prompting you to eat more. This not only exacerbates your insulin resistance but also keeps you trapped in a cycle of poor eating habits and unstable blood sugar levels.
The result? You end up eating more, which can further destabilize your blood sugar, making your insulin resistance worse and fueling an ever-increasing appetite. This cycle of hunger and poor food choices can be incredibly frustrating and difficult to break.
Final Thoughts on Managing Insulin Resistance and Obesity
In the end, managing your food intake and lifestyle choices is crucial for combating insulin resistance and its effects. While insulin resistance can contribute to type 2 diabetes, it can also complicate type 1 diabetes. To prevent or manage insulin resistance, here are some key strategies:
Stay Active: Regular exercise is vital. It doesn’t have to be intense; even a daily walk can make a significant difference.
Eat a Balanced Diet: Focus on consuming nutrient-dense foods that help stabilize blood sugar levels.
Indulge Wisely: Enjoy your favorite treats in moderation. Life is meant to be enjoyed, but balance is key.
Be Conscious of Your Food Choices: Make informed decisions about what you eat to support your health goals.

Remember, staying active and eating well doesn’t mean you have to make drastic changes. Small, consistent actions can lead to significant improvements in your health and well-being.
