Stop counting calories - they don’t tell the whole story. It's the quality of what you eat that matters...

For decades, we’ve been conditioned to see food through the narrow lens of calories. If weight loss is the goal, we’re told to eat less and move more. But when we zoom in on how our bodies actually work, this model falls apart. It’s outdated and misleading.

Of course, total energy intake matters over time, but when it comes to how we feel, how we eat, and whether our bodies are storing or burning that energy, the type of food matters far more in the moment.

Not all foods are created equal.

Different foods contain different molecules: proteins, fats, carbohydrates and fibre, and each of these interacts with our metabolism in unique ways. Calories are only part of the story.

Counting calories doesn't tell us the full story - food quality is what really matters for our health.

Food → Hormones → Metabolic Action

Every time we eat, our body triggers a cascade of hormonal signals. The type of food we eat determines which hormones are released. These hormones then decide what happens next:

·       Will we burn the food for energy?

·       Will we store it (often as fat)?

·       Will we use it for repair and regeneration?

These outcomes don’t hinge on calorie count—they hinge on the composition of the food.

The stock market inside your body

Imagine your metabolism as a busy trading floor. Your internal “traders”—your hormones—shout instructions based on what you eat:

“Burn energy!” “Store fat!” “Hold reserves!” “Build muscle!”

Every bite of food influences this metabolic conversation.

Refined carbs signal: store fat

Refined carbohydrates and added sugars trigger a rapid blood sugar spike, followed by a surge in insulin—our body's primary storage hormone. When insulin is high (especially without physical activity), the message is clear:

“Incoming energy—store it!”

That energy is often stored as fat, particularly around the belly. Here's the critical point: when insulin is elevated, the body can’t efficiently burn fat. It’s stuck in storage mode.

Real foods signal: burn steady

In contrast, protein, fibre-rich vegetables, and healthy fats don’t spike blood sugar. They keep insulin low and stable, allowing the body to access and burn stored energy.

These foods send a quieter, steadier signal to your metabolism:

“We’re fuelled, stable, and ready to keep burning.”

Calories miss the context – we eat food, not numbers

Take two breakfasts:

·       A 500-calorie bowl of sugary cereal

·       A 500-calorie protein-rich meal

In energy terms, they’re identical. In the body, they couldn’t be more different.

Highly refined breakfast cereals vs whole-food, high protein breakfast options

The cereal—being mostly refined carbohydrate—triggers a glucose spike and crash, leading to hunger, cravings, and fat storage.

The protein-rich option supports muscle maintenance, keeps you fuller longer, and stabilises blood sugar.

Calories are just a unit of energy. But the type of molecules in our food is what determines how that energy is used.

If you’re a visual thinker, imagine two roads: one leads to fat storage, the other to fat burning. Both start with what you put on your plate.

These doughnuts are classic examples of blood sugar spiking foods that propagate the craze-graze cycle.

Craving and grazing: the insulin loop

Spikes in insulin don’t just lead to fat storage, they also ramp up cravings. Big swings in blood sugar and insulin throughout the day lead to energy dips, mood crashes, and constant snacking.

It becomes a cycle: eat, spike, crash, crave, repeat. And insulin stays high throughout, keeping the body in fat-storing mode.

This isn’t just a metabolic issue, it’s a mental health one too. Unstable blood sugar has been linked to irritability, anxiety, and brain fog. What we eat shapes how we feel - not just what we weigh.

Focus on food quality, not just quantity

The right foods can switch your body into 'burn mode'. Calorie counting alone doesn’t do that.

What if, instead of asking "How many calories are in this?" We asked:

·       "Will this keep my energy steady?"

·       "Will this help my body stay in fat-burning mode?"

·       "Will this nourish me—or spike and crash me?"

When we prioritise food quality, everything starts to shift: energy, sleep, digestion, cravings, mood—and yes, body composition too.

Eating well doesn't always look like this, but if you can be inspired by the picture and select unprocessed foods where possible, then you're doing a great job!

It’s not about eating less, it’s about eating well

Eating well doesn’t have to mean restriction. It means choosing foods that work with your body, not against it.

We don’t eat calories—we eat molecules. And those molecules provide instructions. The type of food you choose determines whether your body is told to burn or store.

Ready to start?

Tomorrow morning, try swapping your usual cereal or toast for eggs, avocado, and a handful of spinach. Notice how your energy and cravings feel by lunch.
