For years, most people have believed diabetes is simply about eating too much sugar or not exercising enough. But according to Australian health educator Barbara O’Neill, the real story might go deeper—right down to your gut. While mainstream medicine continues to focus on insulin and blood glucose levels, Barbara suggests that poor digestion, chronic inflammation, and hidden lifestyle patterns could be underlying contributors.
This perspective doesn’t replace medical advice, but it opens the door to simple, natural steps that may support better blood sugar balance. If you or someone you love is concerned about prediabetes or managing blood sugar, these insights offer hope—and practical tips you can try right from home.
Let’s take a closer look at what Barbara O’Neill believes is missing from the diabetes conversation.
Could the Problem Start in the Gut?
Barbara O’Neill emphasizes that digestion affects almost everything in the body—including how we regulate sugar. And she’s not alone. Research from institutions like Harvard Health and the Cleveland Clinic has shown that poor gut health can influence metabolic disorders and inflammation.
When your digestive system isn’t working properly, it can lead to:
- Slower breakdown of carbohydrates
- Higher post-meal blood sugar spikes
- Less absorption of key nutrients like magnesium, zinc, and chromium (important for blood sugar regulation)
- Increased gut permeability, which may contribute to inflammation
Barbara recommends starting with digestive wellness as a foundation. This means not just what you eat—but how your body processes it.
Simple digestive health tips include:
- Chew your food slowly and thoroughly
- Drink a small glass of warm water before meals
- Include fermented foods like sauerkraut or kefir
- Avoid eating heavy meals late at night
The Hidden Role of Inflammation
Inflammation is the body’s natural response to injury or infection. But when it becomes chronic—due to stress, poor diet, or environmental toxins—it can interfere with insulin sensitivity.
Barbara explains that inflammation in the gut or liver may create an environment where the body becomes less responsive to insulin, making it harder to manage blood sugar. According to WebMD and Johns Hopkins Medicine, this process may be involved in the development of type 2 diabetes.
You might not feel inflamed, but common signs include:
- Fatigue
- Bloating
- Brain fog
- Joint stiffness
- Cravings for sugar or carbs
Natural ways to support a less inflammatory lifestyle:
- Add anti-inflammatory herbs like turmeric and ginger to your meals
- Use olive oil or avocado oil instead of processed vegetable oils
- Reduce ultra-processed snacks and sugar-sweetened beverages
- Get regular, gentle movement—like walking or stretching
Barbara’s Focus on the Liver
Another angle Barbara O’Neill emphasizes is liver health. The liver plays a critical role in regulating glucose levels by storing and releasing sugar as needed. When the liver is burdened with toxins, processed foods, or excess fat, it may struggle to keep blood sugar steady.
This is often referred to as fatty liver, which is closely associated with insulin resistance—even in people who aren’t overweight.
Barbara encourages natural liver support through:
- Lemon water in the morning
- Bitter greens like dandelion, arugula, and mustard greens
- Fiber-rich foods like flaxseed or chia seeds
- Avoiding alcohol and processed meats
Even small daily habits can ease the load on your liver and support more stable energy and mood throughout the day.
Simple Foods That Support Healthy Blood Sugar
Barbara doesn’t recommend strict diets or deprivation. Instead, she encourages people to return to whole, unprocessed foods that support natural balance in the body.
Some of her favorite blood sugar-friendly choices include:
- Leafy greens – packed with magnesium and antioxidants
- Lentils and beans – slow-digesting carbs with fiber and protein
- Nuts and seeds – healthy fats to slow glucose absorption
- Berries – rich in polyphenols with minimal sugar
- Cinnamon – may help support insulin sensitivity
A simple blood sugar-friendly breakfast idea:
- Warm oatmeal with chia seeds, cinnamon, and a few crushed walnuts
- Add a boiled egg or half an avocado for healthy fat and protein
Don’t Forget the Role of Stress
Barbara O’Neill often reminds audiences that emotional stress can impact physical health more than we realize. When we feel anxious, overwhelmed, or sleep-deprived, the body produces cortisol—a stress hormone that can raise blood sugar levels.
This means even if you’re eating well, unmanaged stress may still be working against your goals.
Ways to support a calm, stable nervous system include:
- Going to bed by 10 PM to support natural hormone cycles
- Taking 5–10 minutes each day for deep breathing or gratitude
- Spending time in nature or natural sunlight
- Limiting screen time before bed
Sometimes, the most powerful changes are the simplest.
Small Daily Habits That Add Up
Instead of quick fixes, Barbara encourages sustainable routines that become part of your daily rhythm. You don’t have to overhaul everything overnight. Just one or two small changes—done consistently—can make a noticeable difference over time.
Try this gentle daily routine for blood sugar support:
Morning
- Drink warm water with lemon
- 15 minutes of walking or stretching
- Protein-rich breakfast with healthy fats
Afternoon
- Stay hydrated with herbal tea or water
- Choose a fiber-rich lunch (e.g., lentils + greens)
- Step outside for sunshine or fresh air
Evening
- Light, early dinner (avoid eating after 7 PM)
- Reflect or journal to unwind from the day
- Aim for 7–8 hours of quality sleep
These habits may not feel dramatic—but they add up.
