Are you struggling to shed those extra kgs despite your best efforts? Don’t lose hope just yet! Let’s delve into a key player in the weight loss game that often flies under the radar: insulin. Understanding how insulin impacts your body could be the breakthrough you’ve been searching for on your journey to a healthier you.
What Is Insulin?
Insulin is a powerful hormone that plays a vital role in regulating your body’s blood sugar levels. It acts as a transport system, ferrying glucose from your bloodstream into your cells. When you consume carbs, they’re broken down into glucose. Any excess glucose is stored in the liver, and when insulin levels dip, the liver releases stored glucose to maintain a stable blood sugar level.
Signs of High Insulin Levels
Identifying high insulin levels can be tricky, but there are some common signs to watch out for. Do you find yourself constantly hungry, battling sugar cravings, or feeling fatigued and unmotivated? These could be red flags signalling elevated insulin levels. Weight gain, especially around the waistline, is also a telltale sign.
The Impact of Elevated Insulin Levels
High insulin levels, medically termed hyperinsulinemia, are closely linked to obesity — though the relationship runs both ways: excess weight can drive insulin resistance, and insulin resistance can make weight gain harder to avoid. It’s a cycle, not a one-way street. Source: a recent review on insulin resistance and metabolic health. By understanding how insulin affects your body, you can take proactive steps to manage it and support your weight loss goals.
What I’ve Seen With Clients — And the Tech That’s Actually Helping
Over the years I’ve watched a lot of clients really struggle with this — especially the ones in high-pressure jobs, working long hours, or pushing hard up the career ladder, often at their own health’s expense. When you’re stretched that thin, insulin control (and everything else about your diet) is usually the first thing to slide.
What’s changed recently is the tech. Continuous glucose monitors — small wearable sensors that pair with an app on your phone — now give people real-time insulin and blood sugar readings throughout the day, instead of just one number from an occasional blood test. They were built for people managing diabetes, but I’ve had clients use them just to actually see, in real time, how their food, stress and sleep are affecting their insulin levels. Having that kind of instant feedback on your phone has made a real difference for some of them — it turns “cut back on sugar” from vague advice into something you can actually watch happen.
Strategies to Lower Insulin Levels and Support Weight Loss
Honestly, most of this isn’t complicated. Eat more protein, eat less carbs, and stop ordering Uber Eats three nights a week because you’re too tired to cook — that alone will do more for your insulin levels than any supplement or hack. Beyond that:
- Embrace a Low-Carb Lifestyle: Opt for a diet that’s low in carbohydrates, as they have the most significant impact on blood sugar and insulin levels. Swap out refined carbs like white bread and pasta for nutrient-rich alternatives like vegetables.
- Practice Portion Control: Avoid overloading your system with large meals that can cause spikes in glucose and insulin levels. Instead, opt for smaller, balanced portions spread throughout the day to help regulate blood sugar.
- Ditch the Sugar: Minimise your consumption of sugary treats and highly processed foods, as they can wreak havoc on insulin levels. Choose natural sweeteners like stevia or indulge in healthier alternatives like dark chocolate or fruit to satisfy your cravings.
- Prioritise Regular Exercise: Physical activity is key to reducing insulin levels and improving insulin sensitivity. Incorporate a mix of aerobic exercises and strength training into your routine to maximise the benefits.
- Stay Active Throughout the Day: Break up long periods of sitting by incorporating movement into your daily life. Take short walks, use the stairs instead of the elevator, and find ways to stay active and engaged throughout the day.

Insulin Sensitivity and Ageing: Why This Matters More As You Get Older
Insulin sensitivity naturally declines with age, which is part of why weight tends to creep on more easily in your 40s and beyond even without major changes to diet or activity. It’s not a reason to give up on the strategies above — if anything, it’s the opposite. Managing insulin through diet, strength training, and staying active becomes more valuable, not less, the older you get.
