Why am I craving sugar? Here’s the science

Thursday 13th Feb 2025 |

After a meal, many of us can’t resist the temptation of a sweet treat to satisfy our sugar cravings. In fact, over the past 30 days, Google searches for “constantly craving sugar” have surged by more than 5,000% across the UK, highlighting just how widespread these cravings are.

While it’s clear that Brits are seeking answers, health experts suggest these cravings could stem from a variety of factors. Lily Keeling, nutritionist and recipe development manager from recipe box delivery service Green Chef comments,

“It’s perfectly normal to fancy something sweet every now and again, but if it’s happening frequently, or after most meals, it could be a sign that you’ve developed a reliance on sugar and your diet is lacking essential nutrients.

“There are several reasons why you might be craving sugar, and if you’re concerned about your intake, I’d always recommend consulting a doctor or nutritionist. They can check for underlying issues such as insulin resistance or a hormone imbalance.”

A recent survey from Green Chef revealed that 15% of Brits are planning to eat less sugar as part of their health and nutrition related New Year resolutions. With this in mind, Lily has shared her top tips for reducing sugar and curbing those sweet cravings.

Limit artificial sweeteners

While swapping sugar for artificial sweeteners often found in low calorie products may seem like an easy way to cut back on sugar while still satisfying your cravings, Lily says to be cautious of this approach. The World Health Organisation released findings in 2023 that artificial sweeteners may not be effective for weight loss and long-term use could lead to an increased risk of type 2 diabetes, along with other health problems.

Reduce Added Sugar or Opt for Intrinsic Sugars

Lily says that at the start of your journey to reducing sugar intake, opting for ‘intrinsic’ sugars (sugars that are inside plant cells and are slower to digest) is one of the best ways to help curb the inevitable cravings.

She comments,

“Fruits, packed with intrinsic sugars along with other vital nutrients, are a better alternative to ultra processed foods with added sugar that are often used to satisfy cravings. Make sure to take fruit with you as snacks throughout the day and discover new ways to incorporate it into your everyday meals.”

Reconsider your diet 

It’s widely recognised that a diet which is high in processed foods and carbohydrates can often increase sugar cravings. Those who crave sugar may do so because their body is needing to boost energy levels, which sugary foods can do, however, Lily advises that this is a short-term fix. Instead, Lily recommends ensuring your diet is nutrient dense and able to fuel the needs of your body. 

To tackle this, Lily recommends reconsidering your daily meals and prioritising a balanced intake of protein, fats, carbohydrates and fibre. These nutrients work together to keep blood sugar levels stable, reducing the peaks and crashes that often drive sugar cravings.
