# Jessie Inchauspé

Jessie Inchauspé (born 1992), also known as Glucose Goddess, is a French biochemist and New York Times bestselling author. She is the founder of Glucose Goddess. She posts content on an Instagram account, glucosegoddess and on a Youtube channel, Glucose Revolution. She is the author of two books on managing glucose levels for wellness: Glucose Revolution and The Glucose Goddess Method. She is a contributor to the French radio station RTL, and presents the 2025 UK Channel 4 show, The Glucose Goddess.
Inchauspé's work rests on what she calls novel "glucose hacks" to reduce one's sugar intake, avoid blood sugar spikes, increase protein, vegetables, and physical activity, and to reduce the side effects of sugar when eaten. The "hacks" that Inchauspé promotes have been described as already "widely accepted" by some critics.

## Early life and education

Inchauspé was born in 1992 in Biarritz, France. An accident in which she broke her back at age 19 led her to being interested in health.
In 2012, she graduated with a bachelor's degree in mathematics from King's College London. She then worked at the University of Pennsylvania as a researcher in statistics. During her time there in 2014, she published A Behaviorally Informed Survey-Powered Market Agent in The Journal of Prediction Markets. In 2015, she completed a master's degree in biochemistry at Georgetown University. While at Georgetown she worked on research linking diet with cancer, and co-authored Paternal programming of breast cancer risk in daughters in a rat model: opposing effects of animal- and plant-based high-fat diets in Breast Cancer Research.

## Career

Inchauspé started her career in 2015 working at the genetics start-up 23andMe as product manager.
While working at 23andMe, Inchauspé got the opportunity to test a continuous glucose monitor as part of an internal pilot study. While she does not have diabetes, she describes the experience as "life-changing", and states that her interest in glucose levels arose from linking glucose spikes to mental health episodes of depersonalization-derealization disorder which she says she had suffered from since her accident at 19. The link between glucose and the disorder has never been corroborated in the scientific literature.
Inchauspé then started the @glucosegoddess Instagram account on which she shared graphs made from her own continuous glucose monitor data to illustrate nutritional science. As of 2024, the account holds 5 million followers.
She describes herself as a "science communicator trying to help people understand how food impacts their body", and that is she is trying to "impact public health on a global scale".
Inchauspé has made a number of television appearances, on Good Morning America in the United States, and the French television show Quotidien.
In 2024, Inchauspé launched a supplement to reduce blood sugar spikes, Anti-Spike Formula.
In early 2025, she presented a Channel 4 television series, The Glucose Goddess.

### Glucose Revolution

In April 2022, Inchauspé released her debut book, "Glucose Revolution: the life-changing power of balancing your blood sugar." Over 1 million copies have been sold worldwide. It is a number 1 bestseller in France, the United Kingdom, Australia, Spain, and Germany. In the US, is a Wall Street Journal bestseller. It is translated into 40+ languages.
In it, Inchauspé shares the importance of glucose regulation for all aspects of our health, and defines her "glucose hacks". She claims that glucose management matters for people with and without diabetes alike, and that you can eat everything as long as you understand when, how, and in which combination.
Inchauspé's work centers around ten "glucose hacks" that she claims are groundbreaking, and reduce blood sugar spikes: Eat foods in the right order, Add a green starter to all your meals, Stop counting calories, Have a savoury breakfast, Have any type of sugar you like – they’re all the same, Pick dessert over a sweet snack, Reach for vinegar before you eat, After you eat, move, If you have to snack, go savoury, and Put some clothes on your carbs. She claims that these hacks can help improve energy levels, reduce cravings, and that blood sugar balance is the key to physical and mental health.

### The Glucose Goddess Method

In May 2023, Inchauspé's released her second book, "The Glucose Goddess Method: The 4-Week Guide to Cutting Cravings, Getting Your Energy Back, and Feeling Amazing", which focuses on four of her "glucose hacks": have a savoury breakfast, drink vinegar before you eat, add a green starter to all your meals, and after you eat, move.
In it, Inchauspé describes an experiment she ran on 2,500 people who improved all aspects of their health as they added the four hacks to their routines for 4 weeks. The book comes with one hundred recipes to implement the method.
The Glucose Goddess was featured on The New York Times Best Seller List and is an international bestseller.

### Anti-Spike Formula

In 2024, Inchauspé announced the launch of her nutritional supplement, Anti-Spike Formula. She describes the supplement as "the best supplement to support your glucose levels." The supplement is marketed as reducing blood sugar spikes by up to 40%, and as having long-term effects on fasting glucose levels and GLP-1.
A 2-capsule serving includes 250 mg of white mulberry leaf extract as Reducose, 250 mg of Eriomin (a citrus flavonoid lemon extract), 85 mg of cinnamon bark extract at a 12 to 1 extraction ratio, equivalent to 1g of cinnamon, as well as lemon extract and an "antioxidant" vegetable blend.
Critics have noted the lack of rigorous clinical trials to substantiate the efficacy of the supplements, despite clinical studies showing that the main ingredient, white mulberry leaf extract, does have a positive effect on glycemic traits.

## Reception

Publisher's weekly comments that "Inchauspé shines in her desire to ensure readers have a good grasp on the facts behind diets, and in her ability to communicate it well."
Most of Inchauspé's "glucose hacks" have been described as being nothing new. Laura Bellows, associate professor of Nutritional Science at Cornell University, said some of the "glucose hacks" are "widely accepted by nutritionists, such as having protein and fat with carbs". While some critics state that her principles are nothing new, others believe that they do not work. Professor François Jornayvaz, department head at Geneva University Hospitals, states: "She hides behind a pseudoscientific appearance to advocate a method which, in my opinion, doesn't work and is based on very little evidence. The scientific studies she cites are highly anecdotal, if not outright false, or not applicable to what she proposes."
Nicola Guess, a dietitian at the University of Oxford, says that "people like the Glucose Goddess look at glucose as though it's the root cause, and if you fix your glucose, you fix whatever problem you have."
Some have commented that Inchauspé is above all, good at marketing. Critics say she has used the medical topic of blood sugar to create a business with a "cult-like following." In The Washington Post, Camille Campbell, the lead designer and founder of Nutrition.DesignLab, comments: "Her messaging is on point. The way she's sharing things is on point. She really makes very smart use of all the aspects of branding and marketing her business."
In 2024, France Info, a French national public broadcasting service, published a report scrutinizing Inchauspé's methodology and claims. While acknowledging that reducing sugar intake and avoiding ultra-processed foods are generally accepted dietary recommendations, the experts criticized her use of a small-scale study involving only 11 patients with type 2 diabetes to support her claim that altering the sequence of food consumption can lead to a 75% reduction in blood sugar spikes. The specialists argued that extrapolating such significant conclusions from a limited study population was scientifically unsound.
Critics also warn of the potential obsession with glucose levels: "glucose has become the new gluten—a medical sensitivity turned nutritional obsession for the masses," writes the Wall Street Journal. Many nutritionists have also warned of the eating disorders that the "glucose hacks" could create.
