“It looks like magic: yet it is science.” This is the tantalizing promise of Jessie Inchauspé’s bestseller, Make your glucose revolution: The fantastic and scientific method to lose weight and regain your energy. “You will be able to eat what you like without gaining weight, without deepening your wrinkles, without damaging your arteries, without suffering any of the other short or long term consequences of a blood glucose level that is too high”, she summarizes. . No wonder the whole world is snapping up the book.

Indeed, her publishing house is out of stock (108,225 copies have been sold in France and more than 500,000 worldwide) and the thirty-year-old, a French woman living in the United States, is cleverly promoting her book and her principles on Instagram, where under the nickname @glucosegoddess, she supports her thesis in 3 languages ​​(English, French and Spanish), followed by 1 million fans. So, should we succumb to this new regime or look at it with suspicion?

What are the ingredients of this “miracle method”?

The researcher describes in detail her food itinerary and her discoveries before concluding that it’s not calories, but glucose in all its forms that is the problem, especially blood sugar spikes. Not just for diabetic patients, but for everyone and for everything: from cardiovascular disease to wrinkles to Alzheimer’s. “In this book, I advise you to smooth the curve of your blood sugar so that the peaks are fewer and fewer and fewer and fewer high,” writes the influencer. For this, she lists a dozen tips.

The main thing: the important thing is not to eat lessbut to eat in a specific order, fibers first, proteins and fats then, starches and sugars last. “According to the researchers, the impact of this sequence is comparable to the effects of drugs prescribed to diabetics to limit glucose spikes.” She therefore advises pback up your meal systematically with a glass of water with a spoonful of vinegarstart with vegetables (fibers), prefer a dessert to a sweet snack, choose dark and dense breads, rich in fibre… Another Commandment: Switch to a Salty Breakfast. Swap cereals with milk for bread, avocado, eggs, cheese… “If our breakfast has triggered a spike in glucose, our blood sugar levels will play a roller coaster until the evening. In addition, it’s in the morning when we wake up, when we are fasting, that our body is most sensitive to glucose.” This is likely to cause some changes in your races…

What do nutritionists say?

Walking after meals, limiting sugar in your diet, adding vegetables to every meal… These common sense tips have a good chance of helping you lose weight, gain energy and age well. “We have known for a long time the interest of having foods with a low or moderate glycemic index: basically, eating vegetables, summarizes Professor Boris Hansel, endocrinologist and nutritionist at Bichat Hospital (Paris). We also know that being permanently in a post-prandial situation (note of digestion) is unfavorable. So it’s been a long time sincewe advise not to snack, to have meals rich in fiber to limit illnesses and we did not wait to say that physical activity was good for your health!”

However, impossible not to recognize in the French woman a certain talent for making certain scientific principles understandable. “The fact that it makes certain notions of biology available to the general public, talking about insulin for example, I find that interesting”, greets Nina Cohen Koubi, nutritionist. Especially since she has a knack for popularizing with humor, based on her youthful mistakes, but also the transformations of members of her community. “It’s true that foods with a high glycemic index cause an insulin spike, which can be followed by a sudden fatigue and cravings, continues the nutritionist. Too sudden a spike in insulin inhibits leptin, the hormone of satiety, which destroys fat cells. But humans are not just about biology, that would be too easy!”

“The interest, like any method, is to tell people to pay attention to themselves, adds Boris Hansel. Whether by looking at your glycemic profile, your number of steps, by tracking calories on a smartphone … The method itself, on the other hand, has no foundation.”

“Scientific”, really?

This miracle method is sold as “fantastic and scientific”. If the author cites a lot of studies, which she also relays on social networks, “she is based on scientific studies on diabetics that she extrapolates for healthy people”, notes Boris Hansel. We cannot therefore compare the dose of glucose, the regularity of the efforts… “There are plenty of experimental methods to limit the increase in blood sugar: cinnamon, peptin, garlic. It’s true in theory, but the real clinical impact, in real life, it doesn’t always work! It’s a classic method of building a story and only looking for work that goes your way.”criticizes the one who is also coordinator of the health awareness channel Pums College*

Worse, it surfs on a well-known recipe: frighten to sell. “To say that the peaks after the meal are in themselves dangerous, that attenuating them makes it possible to live in better health, it is a speculation, continues the doctor. Saying that 80% of the world’s population is in danger is scary, it’s unfounded. So it’s not justified to base yourself on that to change your way of life.”

Why we must keep a distance from what the book recommends

For Nina Cohen Koubi, saying “eat chocolate for dessert and not for snacking” or creating an obsession around a food means imposing new injunctions. “The ban creates envy, it’s counterproductive. And you can fall into eating disorders.“However, nutritionists’ offices are full of people who have chained diets without success. “The danger of such a book is to focus attention on pixie powder and miss the essential”, adds Boris Hansel. For him, concentrating on the order of food is of no interest. “It is necessary to work in a global way, on the quantity of the contributions, on the food behavior, the feeling of satiety, the impulsivity. If you can’t lose weight, it can be a psychological or genetic difficulty…”

Hence the importance of consulting a doctor. “We can’t save money. psycho-emotional care of the person, warns Nina Cohen Koubi. Because it has an impact on weight and health, via cortisol [hormone essentielle à l’équilibre du glucose sanguin] and gut microbiota [réservoir de bactéries].”

“The fact of focusing everything on dietary techniques, this adds to the cacophony in nutrition, continues the nutritionist. I have patients who will focus on an ingredient supposedly good for diabetes, for example cinnamon, but they will forget that they have an impulsiveness on pasta and bread.” The risk is to believe that drinking vinegar would allow you to say goodbye to extra pounds and all pathologies. Not to mention that this advice is not very suitable for people who suffer from acid reflux for example…

Last complaint: Jessie Inchauspé advises to monitor yourself with a blood glucose sensor. A wearable device under the skin that regularly sends data about your glucose levels. “It is a very important device for diabetics, especially when they take insulin, but which has not been proven outside diabetics,” insists Boris Hansel. Diverting this essential companion from its medical function, when access to this device can be complicated, shocked some patients.
