What Is Glycaemic Index (GI)?

Glycaemic index is how fast (and high) 50g of food can raise our blood glucose (sugar) levels.

Glycaemic index is a number give to a food from 0-100 and is typically classed into low-moderate-high categories. The scale goes to 100 as 50g of straight glucose syrup will have a GI of 100 and we compare all other foods to this.

We disagree with this 3 class system. A 4th class of “very low” is required for optimal blood sugar management.

The following page has some common foods split into the 4 different categories. The lower the number is, generally the better it is for diabetes.

Best for: Very high blood glucose levels (BGL’s), keto/Low-Carb diets,  optimal blood sugar control or type 1 Diabetics, late-stage type 2 diabetes. Contains meats, healthy fats, leafy greens, and legumes. Glycaemic index ranges from 0-40

    It depends on what you pair bread/ sugar with and how much protein, fats and fibre the meal contains.

    Carbohydrates are an important energy source. We teach you which types to choose (very low – low GI), the best portion sizes for your body, and what to pair them with to ensure your blood sugars remain stable.

    While we cannot prescribe or recommend reductions in medications, we work closely with your GP and Endocrinologist.

    Many of our clients find that as their nutrition and lifestyle improve, their doctors are able to reduce their medication dosage over time.

    Repairing insulin resistance is possible, but it can be difficult without guidance. 

    People with PCOS or prediabetes often experience more mild levels of insulin resistance which can make it more difficult to manage hunger cues, regulate hormones and monthly cycles and have optimal health. 

    Pairing exercise and very low glycaemic index foods with moderate foods paired with body composition optimisation with a focus on growing muscle can improve insulin sensitivity and our overall health. 

    Yes. As much as we try to fight the stereotype, Dietitians absolutely help with weight loss. Weight loss makes up ~20% of our clientele at the time of writing, and we commonly support people with this goal.

    A REAL Dietitian can help with identifying what has and has not worked for you in the past and tailor a specific strategy to fit into your life (without flipping it upside down). We focus on the highest return on health outcomes with the smallest mental load investment choices first.

    We don’t promise miracles. What we focus on is making the hard parts of health easy

    Not necessarily. While constant high GI foods can spike our blood sugar, there is not enough current evidence to say that normal spikes in our blood sugar on a daily basis can lead to long term negative health outcomes. 

    However, there is a growing amount of evidence suggesting that spiking your blood glucose above 7.8mmol/L (e.eg eating 2 slices of white bread) may lead to increased short term systemic inflammation. 

    The odd spike here and there is not likely to cause long term harm. 

    If every meal is a large spike, there is a higher risk of long term damage and overconsumption of food as many high GI foods are low in satiety and easy to overeat. 

    We recommend speaking with a medical professional for tailored advice based on your unique circumstances.
