Glucose is a carbohydrate, which Inchauspé defines as molecules that are created when carbon and water join together (as happens, for example, during photosynthesis). Plants bind glucose molecules together in various ways and for different purposes, forming three main types of carbohydrates: starch, fiber, and sugars.
During the day, plants make more glucose than they need, and with the help of enzymes, they join the excess glucose molecules into chains that form starch molecules. When a plant needs glucose again, it uses the enzyme alpha-amylase to break some molecules free from the starch chain. In our diet, we get starch from foods like potatoes, oats, and barley.
Inchauspé notes that like plants, our bodies use alpha-amylase to break down starch into glucose. This process starts with the enzymes in our saliva and ends when glucose molecules are freed in our gut.
Inchauspé states that fiber is also made from chains of glucose molecules, but the molecules are joined together in different ways than those in starches. Fiber is tough, holding plants together and keeping them upright.
When we eat fruit and other sweet foods, our guts absorb their glucose and fructose, which then enter the bloodstream. Sucrose takes a less direct route into the bloodstream: Sucrose from sweet foods breaks down into glucose and fructose with the help of enzymes. Some of the fructose molecules from sucrose break down further into glucose, but the rest remain intact.
According to Inchauspé, once carbohydrates break down into glucose in our digestive system, glucose enters cells throughout the body. Organelles in our cells called mitochondria transform glucose into energy, which powers all body systems.
Inchauspé states that glucose spikes happen when the glucose concentration in our body suddenly increases (and then dips) after we eat. In the short term, glucose spikes can make us feel dizzy, nauseous, and exhausted. In addition, they can cause excess sweating, heart palpitations, stress, food cravings, and brain fog.
Second, as the pancreas releases more and more insulin, our cells become resistant to the hormone. Because of this resistance, larger quantities of insulin are needed to store the same amount of glucose as glycogen.
Inchauspé states that elevated glucose levels and frequent glucose spikes can also lead to heart disease in the long term. This is because glucose spikes contribute to cholesterol accumulation beneath the lining of our blood vessels, which sets off heart disease.
Additionally, when our glucose levels make our insulin levels too high, our liver begins producing a small type of cholesterol called LDL pattern B that gets stuck more easily on the edges of blood vessels than other types of cholesterol. High levels of glucose, fructose, and insulin contribute to the oxidization of LDL pattern B, making it even more likely to stick under the lining of our blood vessels. Finally, we experience heart disease when enough cholesterol accumulates to start hindering our blood flow.
Inchauspé also describes how glucose spikes can contribute to mental health struggles and cognitive decline. First, research suggests that people who eat diets that lead to frequent glucose spikes experience more mood disturbances and instances of depression than people whose diets result in more stable glucose levels.
Inchauspé argues that you can dramatically reduce glucose spikes by simply changing the order in which you eat your food. Start your meal with fiber, then eat proteins and fats, and finish with starchy and sweet carbohydrates.
According to Inchauspé, you should eat fiber first because it prevents glucose from being absorbed into your bloodstream too quickly, thus preventing harmful spikes. Fiber accomplishes this in three ways. First, it slows the activity of the enzyme alpha-amylase. As a result, your body breaks down starch into glucose more slowly.
Finally, Inchauspé states that drinking one tablespoon of vinegar diluted in a glass of water before eating something sweet can reduce a glucose spike significantly. Additionally, consuming one tablespoon daily can decrease your overall glucose levels.

#1 We are the pilots of our bodies, and we need to understand how they work in order to maintain optimal health. We need to understand our glucose levels, as they are the easiest to understand and control. If our glucose levels are out of balance, we will feel tired, our hormones will get out of whack, and we will crave sugar.
#4 The three caveats are that your body is a plane, and you are both the pilot and the passenger. You must understand that flattening your glucose curves is the first step to getting your body back to cruising altitude.

By analysing decades of research and running thousands of original experiments on herself wearing a continuous glucose monitor, she has distilled 10 simple and surprising hacks that can be easily incorporated into everyday life.
The author explains that glucose is crucial because it affects how we feel instantaneously, and many other aspects of our health come under control once we get it under control. When our glucose levels are out of balance, we put on weight, have sugar cravings, experience mood swings, our skin can break out, and our hearts can be impacted, to name just a few health issues associated with excess glucose in circulation.
When you eat veggies first, the fibre in them ensures that all foods consumed afterwards travel slower through the digestive tract than they normally do. Consequently, the glucose enters the blood less in a rush, creating a smaller curve rather than a spike of glucose, which is easier to handle for the body.
Adding vinegar to our diet, either a tablespoon in water or a salad dressing helps flatten our glucose curves. It slows the arrival of glucose in the bloodstream and increases the speed at which our muscles soak it up, taking it out of circulation.
Exercise requires energy which in turn needs glucose. Even a 10-minute walk after a meal can burn glucose and flatten the glucose spike from eating. If you eat something sweet or starchy, all the more reason to move afterwards is to burn up some of that glucose and prevent it from being stored as fat.
We often crave a sweet snack between meals when we are low on energy. The idea that something sweet will energise us is actually false. It might briefly boost us, but soon we will crash and want more of the same. It sends us on a dangerous rollercoaster of peaks and troughs in our glucose levels. Many savoury snacks ( i.e. nuts) will give the energy we crave but in a way that sustains our energy levels much longer and without the highs and lows.
Eating carbs alone spikes our glucose levels and plays havoc with our hunger hormones. Have you ever felt hungry soon after eating a cake or croissant? When choosing carbs, make it a habit to add fibre, protein or fat and if possible, eat those first. For example, add avocado to toast, spread peanut or almond butter on rice cakes, or eat some almonds before your croissant. It will help to flatten the glucose spike caused by the carbs and their starches.
A: J.I. got an unexpected crash course (sorry, bad pun!) in glucose spikes when the startup she worked for asked for volunteers to wear a continuous glucose monitor. She was surprised to discover the extent to which different foods she ate caused her blood sugar levels to spike, then crash.
A: I highly recommend reading her detailed description of the effects. But in a nutshell, because glucose is the most basic fuel on which our bodies operate, any dysregulation in our metabolism affects our health in a wide range of ways. On the short term, glucose spikes contribute to cravings, chronic fatigue, poor sleep, impaired immune function, and migraines. They make it really hard to managing diabetes if you are diabetic.
The whole first section of the book, going in depth about metabolism and the role of glucose in our bodies, was a revelation to me. I had pieces of the puzzle before, but I have a new holistic appreciation of my body, what supports it, and what sends it into a tailspin.
Emily, Thanks so much for bringing this to our attention. Sounds like it can be really helpful in moving toward more balance..without being too disruptive. Double win. . As I looked into it further, i noticed a number of people who have actually tried it out reporting very positive effects, including the mother of a diabetic son who was able to really measure results because her son wears a glucose. monitor, and that the 9 hacks they use were amazingly effective, did just what the author said.
