It’s 3 PM and you’re fighting through another tired spell. No doubt, your eyelids feel heavy, your brain is foggy, and you just want something sweet. You ate what you thought was a healthy lunch, yet here you are, craving something in the second meal – classic symptoms that your body may be exhibiting insulin resistance. And it’s time to start an insulin resistance diet
If you are nodding your head, you are not alone in these frustrating symptoms – feelings of constant tiredness, constant sugar cravings, gaining weight around your middle, and that fogginess in your mind that makes thinking heavy and even making simple decisions too hard work? These are often body signals that indicate you are experiencing insulin resistance, which lies at the root of these complaints.
Insulin resistance – the precursor to type 2 diabetes – is a disorder experienced by millions of people throughout the world. The good news I want to instil in you is that insulin resistance is, for the most part, reversible through an insulin resistance diet and lifestyle strategies.
In this guide, you will learn to follow a simple, step-by-step insulin resistance diet strategy, supported by extensive scientific rationale. The aim is to help you understand not just what to eat, but also why the choices you make with food are essential for your body. More importantly, it helps you regain your energy, dissolve the fog in your mind, and get back to being yourself.
What is Insulin Resistance? Let’s break it down
Let me give you an analogy so that this whole process can make a little more sense to you. Think of insulin as a key that unlocks your cells to allow the glucose (sugar) from your food to enter the cells and be used as energy. In a normal person, this process works flawlessly – insulin knocks on the door of the cell, the cell opens up, glucose enters the cell and you feel energized! This is if everything is working properly.
However, with insulin resistance, something has changed. The “locks” of the cell have become rusty. They are now resistant to opening for the insulin’s gentle knock. What does the pancreas do? It panics (think of the story of Humpty Dumpty falling off the wall) and begins to produce more and more insulin. Essentially, it creates more keys and knocks harder, trying to force the cell door open!
This leads to a cascade of events. Your blood is flooded with high insulin and always high glucose levels, making this a toxic cocktail. This combination of high insulin and high glucose levels leads to weight gain (especially around your belly), chronic inflammation, and finally leads to the exhaustion of your pancreas. Eventually, your pancreas just can’t keep producing more insulin and this is when type 2 diabetes develops.
Research shows us that understanding the mechanics of insulin resistance is important for treatment options – and the good news is that once you understand this phenomenon, there are certainly things you can do to reverse it!
Insulin Resistance Diet – Core Strategies
Here is where many people make the mistake – they believe that an insulin resistance diet is about restricting or cutting out sugar completely – yes reducing sugar is the focus but the ultimate goal is much more sophisticated – we want to promote stable blood glucose levels while decreasing insulin demand in the body.
1- Concentrate on Low Glycemic Load (GL) Foods
You may have heard of the Glycemic Index (GI), but I’m going to tell you about something much more practical – Glycemic Load (GL). While GI tells you how fast a food raises blood sugar, GL takes into consideration not only the speed but also the amount of carbohydrates you are actually consuming.
This means you don’t have to give up foods that nourish your body for those that may keep your blood sugars stable. It’s all about choosing foods that create a slow and gradual increase in blood sugar, instead of the rollercoaster rise and falls that leave you feeling drained and wanting to eat again.
2- Eat your Foods High in fiber
Are you amazed yet? Fiber is like having a best friend for your blood sugar. Soluble fiber is found in foods like oats, legumes, apples, and others. When they enter your digestive tract, they form a gel-like consistency and swell up. That gel slows down digestion and helps to slow down absorption of sugar, giving your body the time it needs to digest the glucose, without overwhelming your body with too much at once.
The scientific evidence has demonstrated time and time again that dietary fiber is crucial in our body’s ability to improve insulin sensitivity. In other words, fiber is nature’s way of putting the brakes on blood sugar spikes.
3- Eat Quality Proteins and Healthy (Fat) Foods
This is the beautiful thing about proteins and healthy fats; they can stabilize your blood sugar. When they are eaten with carbohydrates, they tend to slow the digestion down, and with it the digestion of sugar. This means rather than your blood sugar taking off like a rocket, it rises gently like the sunrise.
Plus, protein and healthy fats will keep you feeling full for hours. This is not just willpower – it is the biology of your body creating conditions to naturally reduce your total caloric intake.
Insulin Resistance Diet: What To Eat and Avoid
What to Eat
Let’s get practical. Here is what your plate should look like when you are on an insulin resistance diet:
Non-starchy vegetables (half your plate)
These are your stars: leafy greens, broccoli, cauliflower, colorful bell peppers, zucchini, mushrooms. They are nutrient-dense, high in fiber, and have virtually no impact on your blood sugar. Try to make sure these foods are at the forefront of every meal!
Lean proteins (each meal)
Think chicken breast, fish (especially fatty fish such as salmon that provide omega-3s), tofu, lentils, and Greek yogurt. These foods not only stabilize blood sugar – they aid in building and maintaining the muscle tissue that essentially serves as the glucose storage system for your body.
Healthy fats (don’t avoid!)
You will notice avocados, nuts, seeds, and olive oil are not only allowed on an insulin resistance diet, but encouraged! Research shows monounsaturated and polyunsaturated fats are beneficial in improving insulin sensitivity.
High-fiber complex carbs (with some moderation)
You do not have to give up carbs forever! Berries, quinoa, beans, and a modest quantity of sweet potato could absolutely fall into your insulin resistance diet. Just be mindful of choosing and ideally making, different carbs that are packaged with fiber and nutrients. according to PubMed Central studies Fiber Intake Predicts Weight Loss and Dietary Adherence in Adults Consuming Calorie-Restricted Diets.
What to Avoid
I know this is kind of a bummer, but knowing what doesn’t work with your healing is as important as knowing what does.
Sweetened Beverages and Juices
Liquid sources of refined sugar are extremely problematic, and frankly they hit your bloodstream shorter and harder than any other form of sugar. Even “healthy” fruit juice can create a significant spike in blood sugar levels, while a whole fruit would include fiber to assist in controlling blood sugar responses.
Refined Grains and White Carbohydrates
White breads, white pasta, white rice, pastries, and crackers act similarly to sugar for your body. They are eaten and digested quickly; they are turned into sugar and that creates those dramatic spikes in blood sugar we want to avoid.
Highly Processed Foods and Trans fats
Do not be fooled by what highly processed foods are packed with! Most are filled with unhealthy fats, hidden sugars, and too much sodium. These foods create inflammation in the body and contribute to worsening insulin resistance.
More than Diet: Strong Lifestyle Options
Your insulin resistance diet is powerful, but it can be significantly enhanced with these lifestyle options:
The Role of Exercise
Think of your muscles as your body’s biggest warehouse for glucose. When you do strength training, you are creating more “warehouses” for glucose. When you do aerobic exercise, you are getting your muscles to use glucose more efficiently just like an upgrade to a high-speed computer.
Research has shown that exercise training substantially enhances insulin sensitivity – a few modifications to your lifestyle and you can achieve remarkable improvements! You don’t have to become a gym rat – even 30 minutes of walking after meals can make a tremendous difference!
Importance of Sleep and Stress Management
Poor sleep and chronic stress are like pouring gasoline on the fire of insulin resistance. Sleep deprivation and chronic stress really are an equal opportunity effect. When you are sleep deprived or stressed, your body’s output of cortisol increases significantly, and it is well established that this, in turn, significantly increases your insulin resistance.
You should be aiming for 7-9 hours of quality sleep each night. Practising stress reduction strategies such as deep breathing, mindfulness, meditation, or simply walking peacefully in nature is essential. Your blood glucose will thank you.
Example One-Day Meal Plan:
What might a day of the Insulin Resistance Diet consist of?
Breakfast: Two scrambled eggs with spinach and mushrooms, slathered with half an avocado. Perfect combination of protein (eggs), healthy fat (avocado), and fiber (avocado) gives you stable blood sugar from the get go.
Lunch: A large salad of mixed greens (lettuce, spinach, kale, etc.), grilled chicken, chickpeas, cucumbers and vinaigrette (we recommend an olive oil vinaigrette). It’s nutrient dense and perfectly balanced.
Snack: Full-fat Greek yogurt topped with a small handful of berries (i.e., blueberries, strawberries) and walnuts. The protein and fat found in the yogurt and the nuts help balance the natural sugars in the berries.
For dinner, I made baked salmon with quinoa, roasted asparagus and broccoli. This meal provides omega-3 fatty acids, a complete protein, complex carbs, as well as a good amount of vegetables.
This is simply an example. Your individual needs will differ, depending on your health, activity level, and personal preferences.
Two Essential Products for Insulin Resistance Management
1- Continuous Glucose Monitor (CGM)
Continuous Glucose Monitor (CGM) can support insulin resistance by supplying real-time, personalized information that allows for early detection, monitoring, and management of insulin resistance – in some cases, this can be as early as the first stage, preexisting insulin resistance, prior to having even been formally diagnosed with diabetes.
How CGM Supports Insulin Resistance
CGM allows us to continuously view day-to-day blood sugar changes, which supports uncovering specific patterns related to insulin resistance – frequent glucose spikes, elevated mean glucose and delayed returns to baseline mean glucose levels following meals. Traditional finger-stick glucose tests only allow for a single moment in time, whereas the CGM allows for a much larger and actionable dataset to assess how food, stress, sleep and exercise shape glucose levels in real time.
2- A Set of Resistance Bands
resistance band exercises can help improve insulin resistance by increasing muscle strength, increasing ability to be sensitive to insulin, and positively influencing metabolic health.
Resistance band training provides resistance exercise that promotes increased muscle mass and strength, both of which impact the body’s ability to effectively use insulin. Research indicates that consistent use of resistance bands can reduce the parameters of insulin resistance (such as HOMA-IR) and hemoglobin A1c levels in both healthy individuals and those tangentially related to diabetes and prediabetes.
How fast can I improve my insulin resistance by changing my eating habits?
This is very individualised, but many people will see improvement in a couple of weeks to months with sustained diet and lifestyle changes. Consistency is everything!
Is intermittent fasting a good strategy for a person with insulin resistance?
Some studies have shown that timing when you eat and eating less often can improve insulin resistance by allowing your pancreas to have prolonged rest from producing insulin. Most importantly, intermittent fasting is not right for everyone – check with your doctor first!
Should I be seeing a physician or a dietitian?
Yes! It is beneficial and recommended to see a physician or dietitian for a formal diagnosis and to develop a plan for your individual health challenge. If you have been diagnosed in the past with insulin resistance, this is highly recommended.
