Energy at 11am. Hangry by 3pm. Sweet thing in hand by 9pm. If that’s your day on repeat, you’re not lacking willpower, you’re stuck on the sugar rollercoaster.
Foods high in sugar cause rapid blood sugar spikes followed by crashes. When blood sugars drop, the body signals for a ‘fix’, and cravings perpetuate the cycle. As Registered Nutritional Therapists, we see this every week in clinic: people who blame themselves for snacking, when what they’re actually fighting is their own blood sugar and insulin response.
If you already know you want off this ride, you don’t have to puzzle it out alone. You can book a free 20-minute call and we’ll tell you, in plain English, what’s likely driving your cravings and how to settle them.
Why you can’t stop eating the sweet stuff
Cravings are not the problem. They are the symptom. The real story is what your blood sugar and insulin are doing in the background, hour by hour, meal by meal. When that pattern is off, your brain and hormones make perfectly logical demands for the next snack, and willpower stops being the right tool for the job.
Symptoms of blood sugar imbalance we hear about most often in clinic:
- Poor sleep
- Brain fog
- Anxiety
- Irritability
- Increased sugar cravings
- Low energy
- Weight gain around the middle
Hormone imbalances, such as PMS or perimenopause symptoms.
The science, in plain English
Your body only needs about two teaspoons of broken-down carbohydrates circulating in your blood at any one time. That’s it. Two teaspoons. When you eat refined carbohydrates or simple sugars, blood sugar levels shoot well past that threshold, and insulin is released to mop up the excess and stash it as energy.
The crash
High-sugar foods cause rapid blood sugar rises, triggering excess insulin production. This results in excessive sugar storage, then a crash to lower-than-normal blood sugar, which creates the fatigue, irritability, and renewed hunger that send you straight back to the biscuit tin.
The bigger health issue
Do this often enough and blood sugar and insulin stay permanently elevated. Your cells start to ignore insulin’s signals. That is insulin resistance, and it leads to fat storage, weight gain around the middle, and a higher risk of type 2 diabetes and heart disease.
This is the point where most people Google their symptoms and get scared. You don’t need to stay there. If you can already see yourself in this paragraph, the next sensible step is a Wellness Check, which gives us actual numbers (fasting insulin, HbA1c, triglycerides) so we know exactly which lever to pull for you.
How you can get off the rollercoaster
Top tips to prevent weight gain and stabilise blood sugar:
- Eat plenty of protein with every meal. Protein slows sugar release from carbohydrates and promotes dopamine production, which directly reduces sugar cravings.
- Choose whole grains. These break down more slowly than refined carbohydrates, preventing sharp spikes.
- Watch the hidden sugars in drinks: squash, fizzy drinks, fruit juice and alcohol. These are some of the fastest routes onto the rollercoaster.
- Make sleep a priority. Regular sleep patterns help manage blood sugar. Sleep deprivation elevates cortisol and reduces your blood sugar tolerance the very next day.
- Move more, and lift something. Daily movement plus strength work is one of the most powerful levers we have. Building muscle improves insulin sensitivity, lowers type 2 diabetes risk and supports fat loss in a way that cardio alone can’t.
Want a structured starting point? Our blood sugar walking guide is a free download that tells you exactly when and how to walk to flatten the spike after meals, which is one of the highest-impact, lowest-effort changes you can make.
Ready to step off the rollercoaster for good?
The five tips above will quieten the worst of the spikes. But if you’ve been on this ride for years, or you’re already seeing weight around the middle, pre-diabetes flags or perimenopause symptoms tangled up in the picture, you’ll get further, faster, with the right pair of eyes on your numbers.
Here are three ways we can help, depending on where you are right now.
Start small: grab the blood sugar food guide, a no-cost download that shows you exactly what to put on your plate to keep blood sugar flat between meals.
Get clarity on your numbers. Our Wellness Check runs the right blood markers (including fasting insulin and HbA1c) and gives you a clinical reading of where your metabolism actually sits.
Get hands-on support. Our blood sugar and insulin resistance programme is one-to-one, structured and built for people who want to fix this properly, not just blunt the symptoms. See Lou’s story for what that can look like in practice.
