A Dietitian’s review of the Glucose Goddess Method

Blog, Written by Sophie Corbett

iWhat is the Glucose Goddess method?

The ‘Glucose Goddess method’ is a diet created by biochemist Jessie Inchauspe. The aim is to control blood glucose levels. The book shares a 4-week programme, that involves different hacks for managing blood glucose. The hacks include: having a savoury breakfast, drinking vinegar before eating and eating food in a certain order.

Inchauspe states that her method can support those with and without diabetes to improve – “cravings, constant hunger, fatigue, brain fog, hormonal and fertility issues, skin conditions, wrinkles, poor sleep, menopause symptoms, mental health symptoms, immune system”.

This method has gained popularity online and the book is a bestseller. In this blog we are going to look into the methods and identify if the health claims are valid.

The facts about blood glucose

In healthy people, blood glucose is tightly controlled by hormones and stays within a healthy range.

Currently, there is no conclusive evidence that the small fluctuations of blood glucose before and after eating can be detrimental to health. The Glucose Goddess suggests everyone needs to worry about these small fluctations.

Those with diabetes and other conditions impacting glucose control will need to modify their diet to manage their blood glucose. This is typically done by a multidisciplinary team of health professionals. Not by influencers…

I run a clinic supporting people to improve their relationship with food and overcome eating disorders. I have noticed an increase in anxiety around blood glucose spikes and an increased use of continuous glucose monitors in people who do not have diabetes.  If you don’t have a health condition impacting blood glucose control then using these devices is unnecessary.

Are the claims supported by evidence?

There are a large number of claims made about this method on their website. For example: “it can improve, wrinkles, mental health symptoms, brain function, our immune system, fatigue, fertility issues”.

The evidence used does not test the specific Glucose Goddess method, but instead looks at separate individual factors. Many studies cited on the website are misrepresented. This means that the result is exaggerated, or that it only applies to a certain group of people. In nutrition, to be conclusive we need to test the specific intervention on many different populations over a long period of time. This simply has not been done here.

An example of misrepresented data: The evidence used to support the claim that the Glucose Goddess method can improve brain function is a singular study with a sample size of 49 people, that found that consumption of pure glucose in a fasted state can slightly impact cognitive function (Ginies et al 2018). This is reaching, it does not test the Glucose Godess method and does not indicate that the Glucose Goddess method can improve brain function.

Other concerning messages from the Glucose Goddess

Statements on the Glucose Goddess social media state “coke zero/ diet coke are much better for us than the regular version”. This is despite the fact that the WHO has announced that sweeteners are not better for us than sugar.

In the blood glucose graphs Inchauspe shares on Instagram, she uses her own blood glucose data. This means that the evidence is anecdotal as we all have individual glucose responses to different food.

On the Glucose Goddess website there are many repeated references, that makes it look like there are a large number of studies in cases where there are 1 or 2. As you can see in the picture, this is the same reference, only written to appear different.

On Instagram Inchauspe recommends people to avoid oats, even going as far to share messages that “oats are bad”. Despite the overwhelming evidence of their benefit in blood glucose control for those with type 2 diabetes.

A Dietitian’s take:

  • One size fits all approaches to diet are never appropriate, as we all have individual needs and requirements.
  • Many of the Glucose Goddess’ claims are not supported by evidence and the language being used is very alarmist. Carbohydrates do not need to be feared, oats are certainly not bad.
  • The glycaemic index of a food does not equate to how healthy or unhealthy it is.
  • Some of the ‘hacks’ may be helpful for those with type 2 diabetes. However the programme needs to be studied independently before it can be considered as an evidence-based intervention.
  • If you do not have a health condition that impacts blood glucose control, then you do not need to monitor, or worry about your blood glucose. Instead it is best to focus on an overall balanced diet. Eating in a way that supports your individual health needs and how you like to eat.

Update for 2024: The Anti-Spike formula.

In January 2024 Inchauspe released a supplement claiming it could reduce blood glucose spikes. The formula itself, just like the Glucose Goddess method, is untested. This is another case of a high profile individual profiting from the ‘worried well’. Pathologising a normal bodily function and then profiting from the solution to this ‘problem’.

Health professionals are additionally concerned that the Diabetes community may mistakenly see this as an alternative to tested methods of diabetes management.
