The Hidden Impact of Sugar: How It Affects Energy, Mood, Hormones, Sleep, and Inflammation
The Surprising Link Between Sugar, Hormones, and Everyday Symptoms
Many women I work with are surprised to learn just how much sugar is affecting their health. From constant sugar cravings and afternoon energy dips to PMS and peri-menopause struggles, the link between sugar and hormones is stronger than you think.
And it’s not just the obvious treats like chocolate or cake, hidden sugars in everyday foods play a big role too. Over time, these can lead to inflammation, weight gain, insulin resistance, and food noise that leaves you feeling out of control around food.
Once you understand what’s really happening with your blood sugar, you can take back control.
The Ripple Effect of Sugar on Your Body
When we rely on quick carbs and sugary foods to get through the day, it affects far more than our waistline. Here’s how sugar impacts your body:
Energy → A sugar high always leads to the dreaded crash. That’s why so many women hit the wall around 3pm, reaching for another coffee or snack just to keep going.
Mood → Low blood sugar can show up as irritability, anxiety, brain fog, or low motivation. If you’ve ever been “hangry,” you know the feeling!
Hormones → Blood sugar swings can make PMS worse, intensify peri-menopause symptoms, and contribute to hormone imbalance.
Sleep → Waking up at 3am or tossing and turning can often be linked back to blood sugar dips caused by hidden sugars earlier in the day.
What Is Food Noise?
If you’ve ever felt like your mind is constantly thinking about food, when your next meal is, whether you should have a snack, or battling with “should I/shouldn’t I” thoughts about sugar, that’s called food noise.
Food noise isn’t about a lack of willpower. It’s a sign your blood sugar and hunger hormones are out of sync. When your body is on a sugar rollercoaster, your brain stays hyper-focused on finding more food for energy, creating mental chatter that’s hard to switch off.
The result? Constant thoughts about food, cravings that feel impossible to resist, and feeling like you’re fighting yourself all day long.
Balancing your blood sugar is one of the most effective ways to calm food noise, because when your body feels fuelled and safe, your brain can finally switch off from obsessing about food.
Why Sugar Cravings Happen (and How They Lead to Fat Storage)
Sugar cravings and food noise are not about willpower. Your body is designed to keep you alive and energised. When blood sugar crashes, your brain will push you towards the fastest fuel it knows: sugar and refined carbs.
And when we consume more sugar than the body can use right away, it gets stored as fat. This doesn’t just come from cakes or chocolate, even white bread, pasta, and rice break down into sugar in the body and can contribute to the same rollercoaster of highs, crashes, cravings, and fat storage.
Over time, this cycle can increase the risk of insulin resistance, one of the key drivers of stubborn weight gain, low energy, and metabolic issues.

The Food Industry & Ultra-Processed Foods (UPFs)
The food industry has a lot to answer for.
Many ultra-processed packaged foods (UPFs) — even the ones marketed as “healthy,” “low-fat,” or “high-protein” — are loaded with hidden sugars and refined carbs. These products are engineered to be addictive, keeping you coming back for more and feeding both sugar cravings and food noise.
Think flavoured yoghurts, cereal bars, “protein” snacks, ready meals, and sauces. The labels can be misleading, making it hard to know what’s really in your food.
This isn’t your fault. The system is designed to make over-consuming sugar easy and spotting hidden sugars difficult.
What About Artificial Sweeteners?
When people start cutting back on sugar, it’s tempting to reach for “sugar-free” drinks or foods with artificial sweeteners. While they don’t contain the same calories as sugar, they can still have an impact on your health.
Cravings → Sweeteners keep your taste buds trained to expect high levels of sweetness, so food noise and sugar cravings often stick around.
Gut health → Some artificial sweeteners can disrupt the gut microbiome, which plays a key role in digestion, metabolism, and even hormone balance.
Hormones → Early research suggests sweeteners may still affect insulin response and appetite regulation in some people.
The bottom line: while an occasional diet drink isn’t the end of the world, relying on sweeteners isn’t the solution. Your body thrives best on real, whole foods with naturally balanced flavours, not a constant stream of hyper-sweetened products.
Sugar, Inflammation & Long-Term Health Risks
The impact of sugar isn’t just about today’s cravings or energy crashes. Over time, regularly consuming too much sugar drives inflammation in the body.
Chronic inflammation is like a slow burn that puts stress on your system. It has been linked to:
Insulin resistance and type 2 diabetes
Hormone imbalances that worsen PMS, peri-menopause, or menopause symptoms
Weight gain around the middle
Increased risk of heart disease
Fatigue, brain fog, and even joint pain
The good news? Lowering sugar intake and focusing on blood sugar balance can reduce inflammation, calm food noise, and support hormone health.
🔎 Hidden Sugars Watch List
Sugar isn’t just in sweets and desserts; it’s hidden in everyday “healthy” or packaged foods. Here are some of the biggest culprits:
Breakfast foods → flavoured yoghurts, granola, cereal, instant porridge sachets
Snack bars → protein bars, “healthy” flapjacks, fruit bars
Drinks → smoothies, fruit juice, flavoured waters, energy drinks
Condiments & sauces → ketchup, sweet chilli sauce, salad dressings, stir-fry sauces
Breads & wraps → especially white breads, bagels, and tortillas
Low-fat or “diet” products → often sugar is added back once fat is removed
Convenience meals → ready-made curries, soups, pasta sauces
Alcohol → cocktails, wine, tonic water
💡 Tip: Always check labels. Sugar hides under names like glucose, fructose, maltose, dextrose, syrup, nectar, honey, molasses. If it ends in -ose, it’s probably sugar.
Simple Steps to Balance Blood Sugar & Calm Food Noise
When you start eating in a way that balances your blood sugar, everything changes. Here’s what your body really needs:
Protein: keeps you fuller for longer and helps stabilise cravings.
Fibre: slows down sugar release, supporting digestion and energy.
Healthy fats: balance hormones and keep hunger steady.
Smart carbs: whole, slow-release sources like quinoa and sweet potato that fuel you without the crash.
When blood sugar is steady, you’ll notice:
✨ Calmer cravings

FAQ: Sugar, Food Noise & Hormone Health
1. What is food noise?
Food noise is the constant mental chatter about food — cravings, “should I/shouldn’t I” thoughts, or always thinking about your next meal. It happens when blood sugar isn’t stable and hunger hormones are out of balance, making your brain focus on food for quick energy.
2. Does sugar really cause inflammation?
Yes. Eating too much sugar, especially from hidden sugars and ultra-processed foods, can trigger chronic low-grade inflammation in the body. Over time, this can contribute to hormone imbalances, joint pain, fatigue, and increased risk of conditions like diabetes and heart disease.
3. Why do I crave sugar in the afternoon?
That 3pm crash usually happens when your blood sugar spikes earlier in the day (from things like cereal, toast, or sweet coffee drinks) and then drops quickly. The brain then pushes you to seek sugar or caffeine to get energy back up fast.
4. Are carbs bad for you?
Not at all — your body needs carbs for energy. The key is choosing smart carbs like oats, quinoa, brown rice, or sweet potatoes. These release energy slowly and keep blood sugar steady, unlike refined carbs such as white bread, pasta, or pastries.
5. How can I calm sugar cravings and food noise quickly?
Start by balancing meals with protein, fibre, and healthy fats. These nutrients keep you fuller for longer and reduce sugar crashes. Simple habits like walking after meals, staying hydrated, and getting enough sleep also make a big difference.
6. What’s the best way to start reducing sugar?
The easiest way is to spot hidden sugars and make swaps one step at a time. You don’t need to cut everything at once — focus on building balanced meals that support blood sugar. That’s exactly what we do inside the 7-Day Sugar Reset.
