Quentin Crisp says, “Repeat yourself loudly and often” and so I’m repeating myself on blood sugar regulation.
I guess if I had to leave a legacy in the world of natural health and lifestyle medicine, if I could sum everyone’s problems down to one key major concept and one key take-home action plan it would be: blood sugar regulation and: eat protein.
Last week was pretty busy in my little homegrown virtual naturopathic practice and I found myself repeating myself loudly (well, in a normal volume voice) and definitely often, the importance of eating protein at every meal and the connection between their symptoms and blood sugar with virtually every patient I saw.
All of my patients last week seemed to be suffering from some combination of the following symptoms:
Fatigue, anxiety, overwhelm, disrupted, restless, and non-restorative sleep, sugar cravings, emotional eating, binge-eating/stress-eating, nausea and bloating, PMS, migraines, low focus and concentration, low libido, low motivation, poor exercise recovery, and weight gain/puffiness/body image issues.
Of course, many of these symptoms were presented as being unrelated to the other. Perhaps stress and stress-eating were related, but sugar cravings and low motivation weren’t necessarily related in my patients’ minds. Neither were their sugar cravings, overwhelm and low libido.
And yet, the common thread that connects all of these symptoms is, you guessed it: blood sugar.
I explained to one patient: even if I gave you a magic wand, that you could wave to make all of your life’s problems disappear, you would probably still be feeling that deep, disconcerting, restless, anxious, “all-is-not-well” feeling in your gut. The reason for this? Blood sugar dys-regulation.
Our body has certain physiological mechanisms that it likes to keep tightly regulated. Among them are blood levels of our sugar (which controls the amount of fuel our brain has for its minute-to-minute functioning), carbon dioxide, salt, and water. When these levels drop in the body we start to feel off. Our stress response is triggered.
Imagine the feeling of holding your breath, as carbon dioxide starts to build up in your blood, you’d pay someone a million dollars to be able to take a breath. Similarly, if you’re seriously thirsty it’s likely all you can think about.
When our blood sugar drops, we feel terrible. The symptoms are anxiety, shakiness, fatigue, low mental energy, burnout, decision fatigue, waking up in the middle of the night, irritability, dizziness and weakness, and an unsettled, doom and gloom feeling. Most of all, however, we crave sugar.
Despite all of the symptoms my patients were expressing last week, one of the main issues they were contending with were sugar cravings. “I just don’t have the motivation to cook a meal”, one patient expressed, “and so I end up eating a bag of chips for dinner, even though I’m not really hungry.”
“You are hungry,” I explained, “the hunger is just not manifesting in the way that you’re used to.
Let me repeat this loudly, ala Quentin Crisp: if you ever find yourself at the end of a bag of chips, or a plate of cookies, or a pile of donuts–you were hungry.
Eating disorder expert Tabitha Ferrar highlights a phenomenon in people recovering from anorexia as “mental hunger”. Physical hunger, the grumbling, gurgling, empty feeling in your stomach is the result of ghrelin and gastric motility, which builds up when leptin levels fall and our stomach is physically empty and creates what many of us assume are the sensations of “true hunger”.

However, these symptoms require energy form our body to produce. This is the reason why people with hypothryoidism are constipated–gastric motility takes metabolic energy.
If your body is malnourished, such as the case of anorexia, or even chronic stress and under-eating throughout the day, we often don’t get these signals of “true” hunger.
Our bodies simply don’t have the battery power to create these symptoms. And yet, we need nourishment, particularly we need to elevate our blood sugar to supply our brains with energy.
And so our body sends our signals of “mental hunger”, that feeling of “I can’t stop thinking about the chips in the cupboard”, that often leads to mindless binging as our body tries to replenish its reserves.
If you’re craving sugar, emotionally eating, devouring chips in the afternoons or evenings, or feeling decision fatigue/ or “lack of willpower”, you might need to start focussing on your blood sugar.
Blood sugar dysregulation is also tightly connected to our moods. Think of our body’s homeostatic mechanism as a tightly regulated machine, a fuel gauge on our body’s resources, which are needed in times of stress. When our blood salt, sugar or water levels dip, and our blood CO2 levels rise, we start to feel uncomfortable. This can be remedied by drinking water, sighing, deep breathing, or eating something. When these levels fluctuate and we fail to notice, our body releases stress hormone.
Cortisol is our stress hormone, but it’s also the hormone that plays a role in blood sugar regulation. When blood sugar dips beyond homeostatic levels, cortisol steps in to save the day. Low blood sugar is a stressor on the body. This might look like morning anxiety, feeling tired and wired, waking in the middle of the night unable to fall back asleep.
Again, you might not feel hungry during these moments–just overwhelmed, anxious, irritable, unsettled, weak, dizzy, and fatigued.
You’re in a fight with your partner. You’ve been cleaning out the garage and it’s hot out. You’re annoyed at the way he breathes, at the slow methodical way he goes through your stuff. The mess feels overwhelming, the heat feels stifling. You leave in a huff, ready to set fire to the entire operation.
Grumbling and fuming, you go inside. You take a breather, you eat something, you exhale deeply, you drink some water.
Gradually, as your body starts to shift into physiological neutral, your perception starts to change. The garage feels slightly more tolerable. It’s really just above moving one box at a time, going through it and then starting on the next one. You can do it.
Before you know it, you’re done.
When blood sugar is low our prefrontal cortex, the “ego”, “decision-maker”, executive functioning, planning and cognitive part of the brain, becomes depleted. We might call this “decision fatigue”, “willpower fatigue” or “ego depletion”.
A New York Times article states,
“Administering glucose completely reversed the brain changes wrought by depletion…
“When glucose is low, [your brain] stops doing some things and starts doing others. It responds more strongly to immediate rewards and pays less attention to long-term prospects.”
In essence, you stop being able to make calm and effective decisions.
Brain sugar levels (the brain uses up 60% of available blood sugar) directly contribute to the feeling of being “solid”–able to make rational decisions, to respond to fears and anxieties, to emotionally regulate, to make competent and calm decisions.
When our blood sugar levels dip we start to spiral: we might think erratically, gloomily, catastrophically, and irrationally.
I had a patient who crashed at 3pm everday after school, when his major depression would “come back”. I asked him what he had for lunch, to which he replied he often worked through lunch. Breakfast was a croissant or piece of toast.
His first real (and only) meal was at dinner. The rest of the day was a sea of grazing on ultra-processed foods, sugar and white flour. No real food in sight.
Scarfing down an emergency granola bar every time blood sugar drops is one solution, however whenever we eat carbohydrates on their own, particularly the quick-release carbs like white sugar, or refined grains, our blood sugar spikes. Soon after, insulin is released, causing it to drop again.
Many of us start the day without food, or with a measly breakfast of toast or cereal, or some other carb-only meal. As I tell patients, though, a serving of carbohydrates is not a real meal.
You know what I mean: a bagel for breakfast, a sandwich and pb for lunch, a plate of pasta for dinner. Carbs, while an important part of a complete meal, are completely inadequate at keeping you fuelled for the hours of mental, emotional and physical labour you engage in between meals.
Does this mean you should eat low-carb? No, not necessarily.
What it means is that a meal contains fats, carbs, and protein. Therefore all meals, especially breakfast, and even snacks, should combine those three macronutrients to assure proper fuelling and blood sugar regulation.
When you eat a proper meal in the morning, your blood sugar rises slowly. It requires less insulin to get the fuel into your cells. Your blood sugar is metered out slowly throughout the next few hours instead of being rapidly absorbed.
This means no more spikes and crashes–in blood sugar, energy, mood or cravings. A proper meal provides hours of calm focus, more willpower, and more ability to concentrate and emotionally regulate.
Instead of just toast in the morning, add about 20g of protein to your meal: a scoop of protein powder, 3-4 eggs, a piece of chicken, 3 tbs of collagen powder– in essence, have a proper meal.
Then, for lunch do it again–have a chicken breast on your salad, or a piece of salmon or beef.
Make yourself a smoothie with protein powder. Have a cold soak oats with collagen powder. Make yourself an omelette. Have a bean soup with 1 cup of beans.
Substitute your wheat or rice pasta (which is just carbohydrate) for a legume pasta made of mung bean or lentils, or black beans, which contain fibre and protein and are easier to make into a fast, complete meal.
When patients start having complete meals, starting with breakfast, their change in mood is often dramatic. They feel more mentally and emotionally stable. They have more energy.
Often we feel we get our second wind in the evening: (“I’m more of a night owl”). But so many of us work through our morning meals and only sit down to a complete meal at dinnertime. Maybe your “second wind” is actually just your first wind, purchased from the proper meal you had when you finally sat down and nourished your body.
What about intermittent fasting? Whenever I speak about breakfast there’s at least one DM or question, or “but I thought that…” and the topic of intermittent fasting almost always comes up.
Giving the body a break from eating is a good idea. For about 12 hours, if possible, stop eating.
This usually means stopping eating 3 hours before bedtime and creating an eating window from something like 7am to 7pm.
12:12 (12 hours of fasting and 12 hours of eating) can be great for resting the digestive system and supporting sleep. However, many of my patients use more extreme version of “intermittent fasting”, such as the 16:8 (16 hours fasting and 8 hours feeding) as a go-ahead to skip breakfast.
They wake up and get through the morning on coffee (with cream and sugar, which isn’t actually a real “fast”), and then eventually binge on sugar and chips after dinner, when they finally give their bodies permission to eat. It’s rare that they see the connection.
Most of us attribute the feelings of lack of control around food an issue with emotional eating and willpower. I find that in 99% of cases, “emotional eating” us usually just a result of blood sugar dys-regulation, protein deficiency and under-nourishing earlier on in the day.
A morning without food is a stressor on the body. Female bodies in particular respond to stress by becoming more insulin resistant, which further affects blood sugar dys-regulation and affects metabolic health–this is not what you want.
If you’d like to restrict your eating window, research shows that removing any after-dinner snacking (when our bodies are naturally more insulin resistant) is the way to go.
It’s also important to take a Protein Inventory. Sometimes I just have patients track their protein intake on a website or app like cronometer.com
The exercise is often enlightening, as patients are able to see how the protein density of their diet connects to their mood and energy.
I often get them to track their food for a few days to a week and then ask them: How do you feel on a higher protein day, where you meet your nutritional needs vs. a low protein day? What is your energy like? Your sugar cravings? Your mood? Your mental focus and clarity?
Conditions like OCD, ADHD, depression, anxiety, PMS, PMDD, cognitive issues, dementia, diabetes, pre-diabetes, weight gain, and bipolar all have roots in blood sugar regulation.
Blood sugar dys-regulation, over time can start to result in insulin resistance (often detected far before any changes to lab blood glucose start to show up).
Insulin resistance is the process in which the cells stop responding to insulin, requiring more insulin to be released. This causes inflammation and weight gain and, over time, elevated blood sugar. Insulin resistance can contribute to mood and hormonal issues, cognitive issues, like dementia, and metabolic conditions over time. This is definitely something you don’t want.
If you think you might have insulin resistance (characterized by sugar cravings, fatigue, abdominal weight gain, difficulty losing weight, hormonal issues, mood issues, low energy, and cognitive issues) consider getting your fasting insulin and fasting glucose tested. These two numbers can give you a HOMA-IR score, used to gauge insulin resistance, so you can work to reverse it before it progresses to pre-diabetes and type II diabetes.
Often insulin resistance, inflammation and stress are a never-ending cycle and all need to be addressed, with blood sugar regulation as a key strategy to getting your body’s insulin signal working again.
Signs that your metabolic health is healing are more energy, less cravings, better mood, better sleep, and some weight loss (which usually starts occurring about 6 weeks into a lifestyle change program).
Low calorie diets can also be a significant stressor on the body affecting blood sugar. Making sure that your fat and protein intake are sufficient (aiming for about 1 g of protein per lb of body weight for an active person) is essential to regulating blood sugar, cravings, mood and energy.

So, how do you take control of your sugar cravings today?
Here are some places to start:
- Start your day with a complete breakfast that includes fat, carbs and 20 g of protein
- Eat full meals regularly throughout the day
- “front-load” your calories, eating 60% or more of your food before 1pm
- Aim for 1 g of protein per lb of body weight, or 90g of protein as a minimum
- Track your protein intake along with your mood, energy levels and cravings so that you can have more agency over your food choices, dietary patterns and symptoms.
- Have ready-to-grab protein sources like pumpkin seeds, eggs, protein powder, legume pasta, precooked chicken breasts, canned salmon, and so on.
- If you’re going to try Intermittent Fasting start slowly, begin by avoiding late-night snacking or snacking before dinner.
Finally, book an appointment if you feel ready to support your metabolic health and get your nutrition right to support your hormones and mood!
