BBC Reporter Quits Sugar for 6 Weeks, Feels Amazing

When BBC journalist Melissa Hogenboom decided to quit sugar for six weeks, she wasn't prepared for how much better she'd feel. The self-confessed chocolate lover gave up all added sugars in 2026 and discovered that her notorious post-lunch energy crash simply vanished.

Sugar hides in surprising places, and Hogenboom quickly learned just how sneaky it can be. A single deli sandwich contained nearly 6 grams of added sugar, while a bolognese ready meal packed in 9 grams.

The challenge wasn't easy at first. During the initial days, Hogenboom craved sweets intensely, especially at social events where treats tempted her constantly. She found herself staring into her fridge, searching for something interesting to eat.

But something remarkable happened as the weeks progressed. Her energy levels stabilized throughout the day, giving her a consistent feeling of alertness she hadn't experienced before. The brain fog lifted, and she felt genuinely better.

The science backs up what she experienced. Research shows that high-sugar diets spike blood sugar rapidly, which can lead to insulin resistance and increase diabetes risk over time. One study found that people who consumed sugary drinks for several weeks showed double the amount of fat in their liver, even when eating the same total calories.

Sugar affects our brains in powerful ways too. When we eat it, our brain chemistry changes similarly to what happens with opioid addiction, explains Lina Begdache, a registered dietitian at Binghamton University. This explains why those first few days felt so difficult for Hogenboom.

The good news is that most people eat way more sugar than necessary. US adults consume about 17 teaspoons daily, while guidelines recommend fewer than 12. UK guidelines suggest even less at just 7 teaspoons per day.

Hogenboom continued eating natural sugars found in whole fruits, which work differently in our bodies. The sugars in an apple are bound up in cells, meaning our bodies have to work harder to obtain them, creating a slower, steadier energy release.

Why This Inspires

Hogenboom's experiment proves that small changes can create big results. She didn't attempt perfection or cut out every carbohydrate. Instead, she focused on eliminating added refined sugars while still enjoying whole foods and fruits.

Her experience shows that the constant energy crashes so many people accept as normal aren't inevitable. By removing hidden sugars from everyday foods, she found a steadier, more vibrant version of herself.

The best part? Anyone can try this experiment, and the results might surprise you.
