I recently read the book, The Glucose Revolution: The Life-Changing Power of Balancing Your Blood Sugar”, by Jessie Inchauspé. This is a book, but Inchauspe also has a huge instagram following under the name, The Glucose Goddess. Inchauspe has gained significant attention for promoting her “hacks” to flatten glucose spikes and improve health”. While the book draws connections between blood sugar regulation and well-being, many of its claims oversimplify or misrepresent complex nutrition science. This blog aims to break down the book’s core arguments, separate evidence from hype, and provide a more balanced perspective on blood sugar management.
Non diabetics seem to be the majority of Inchauspe’s target market. However, it is completely natural to have a rise in glucose after eating foods containing carbohydrates. And guess what? Nothing bad is going to happen to you. Eating an ‘undressed apple’ , this is OK! In fact, this is fabulous. Apples have been shown to decrease CVD risk. You don’t have to have nut butter with it. How much nut butter does she want us to eat anyway? Dear goodness. I’m all for eating nuts, but come on.
May I also add… when I began talking to my book and telling it how wrong it was… I knew I had to write this blog. Clearly, I had something to share with the community. And seriously, how many hacks do we need in this world…
1. Misleading Cause-and-Effect Relationships
The Glucose Revolution argues that blood sugar spikes are the primary cause of many health issues, from weight gain to fatigue, inflammation to mental health. While glucose regulation is essential, it’s inaccurate to claim that fluctuations in blood sugar alone are responsible for such a wide range of problems. This theory is FAR too simplistic and paints a black and white picture of our overall health. Health is influenced by numerous interconnected factors like genetics, physical activity, overall diet, and sleep, not just blood sugar. Rises and falls in blood sugars are a normal part of our day to day life. We do not need to wear a continuous glucose monitor (CGM) to keep track of our levels. This feels obsessive and fearful to me, potentially contributing to disordered eating patterns.
Reality Check:
Small glucose fluctuations after meals are normal and healthy for most people. In healthy individuals, the body manages these spikes through insulin. Making blood sugar management the “be-all, end-all” of wellness ignores other crucial pillars like nutrient adequacy, mental health, and stress management.
2. Demonizing Carbohydrates and Food Timing
Inchauspé suggests various hacks—like eating vegetables before carbohydrates—to blunt glucose responses, implying that this is necessary for everyone. While this may slightly reduce postprandial glucose levels, it creates the impression that everyone needs to eat in this way to stay healthy.
Reality Check:
The glycemic response varies between individuals based on genetics, activity level, and insulin sensitivity. Healthy individuals do not need to avoid glucose spikes at all costs. More importantly, focusing obsessively on food sequencing can create a negative relationship with eating.
Carbohydrates are essential for energy, particularly for active individuals. Timing carbs strategically might be helpful for people with diabetes or insulin resistance, but for the general population, this approach is unnecessary and restrictive.
3. Overstating the Impact of Glucose Monitoring for Everyone
The book encourages the use of continuous glucose monitors (CGMs), implying that tracking blood sugar is useful for non-diabetic individuals. This advice fuels the notion that constant vigilance over glucose levels will unlock better health.
Reality Check:
While CGMs are vital tools for people with diabetes, they are not clinically recommended for the general population. Daily glucose monitoring for healthy people can lead to unnecessary anxiety and hyper-focus on minor fluctuations that don’t indicate any real health problem. The human body is resilient, and it’s normal for glucose levels to rise and fall throughout the day.
Additionally, research does not support CGM use as an effective tool for weight loss or improved metabolic health in healthy individuals. The variability in glucose readings between people means the data is often difficult to interpret meaningfully without context.
4. Lack of Strong Evidence for “Hacks”
Inchauspé’s recommendations—like adding vinegar to meals or exercising immediately after eating—are presented as science-backed methods to “flatten the glucose curve.” While some research shows these practices can have minor benefits, the evidence is not conclusive, and the impact on long-term health is unclear.
Reality Check:
For most healthy people, the body already manages post-meal glucose effectively. Minor changes like vinegar consumption or post-meal walks may offer some benefits, but they aren’t revolutionary. Importantly, they should not be treated as magic solutions or substitutes for broader lifestyle improvements like eating a balanced diet, engaging in regular exercise, and sleeping well.
5. Ignoring the Bigger Picture in Nutrition
Focusing narrowly on blood sugar as the key to health is problematic because it overshadows the importance of other aspects of nutrition. A well-rounded diet that includes all food groups—proteins, fats, and carbohydrates—offers more sustainable health benefits than obsessing over glucose levels.
Reality Check:
By concentrating too much on specific glucose-related hacks, the book risks promoting an unhealthy relationship with food. True health comes from balance and sustainability, not micro-managing blood sugar levels. A balanced diet rich in fiber, whole foods, and healthy fats supports metabolic health without needing complex food rules.
Conclusion: Glucose Spikes Aren’t the Villain
While The Glucose Revolution taps into the growing interest in blood sugar management, it often stretches the science beyond what is reasonable for the general public. For healthy individuals, occasional glucose spikes are not harmful. The body is equipped to handle them as part of normal metabolism.
If you’re concerned about blood sugar, simple habits like eating balanced meals, staying active, and managing stress are far more effective (and sustainable) than obsessing over food sequencing or wearing a glucose monitor. Rather than chasing the latest wellness trend, focus on building healthy, enjoyable eating patterns that promote long-term well-being.
A Final Word of Caution
It’s essential to approach popular nutrition books with a critical eye. While catchy hacks can seem appealing, sustainable health changes require balance and individualized approaches—not rigid rules. If you’re dealing with blood sugar concerns or conditions like diabetes, work with a registered dietitian or healthcare professional for evidence-based advice tailored to your needs.
