Understanding ACT: A Science-Backed Approach to Overcoming Sugar Addiction

When it comes to sugar addiction, most people focus on cutting down on sugar, managing cravings, or finding sugar-free snacks. But here’s something that often gets overlooked: your mindset.

If you don’t learn how to handle your thoughts and emotions differently, you’ll keep falling back into the same sugar dependency cycle. That’s where Acceptance and Commitment Therapy (ACT) comes in; a powerful, science-backed method used worldwide to treat everything from stress and anxiety to emotional eating and addiction.

Why We Keep Craving Sugar

Many sugar cravings aren’t about physical hunger; they’re emotional. Stress, boredom, or loneliness can trigger a sudden urge to eat something sweet. It’s not because your body needs energy, but because your mind is searching for comfort or escape.

You then can eat something sugary, feel better for a few minutes, and then the guilt creeps in. This leads to more stress, more cravings, and more sugar. This is what Dr Russ Harris, in his book The Happiness Trap, calls the happiness trap: the endless cycle of chasing good feelings and avoiding bad ones.

In the real world, you can’t avoid uncomfortable feelings. But you can learn to respond to them differently.

Thoughts Aren’t Facts

ACT teaches something incredibly freeing:

Thoughts aren’t facts; they’re just stories your mind tells you.

When a sugar craving appears, you might think: “I really need something sweet right now.” Instead of obeying that thought or fighting it, ACT encourages you to accept it.

Try saying: “I notice I’m having the thought that I need sugar.”

That simple phrase helps you step back and see the craving for what it is: just a passing thought, not a command. You can even add a touch of humour: “I notice I’m having the thought that I need sugar. Nice story. Thanks, mind!”

It might sound silly, but it works. This slight mental shift helps defuse the power of the craving and puts you back in control.

Defusion: The Secret to Breaking the Cycle

In ACT, this process is called defusion: learning to separate yourself from your thoughts rather than getting caught up in them. You don’t need to fight your cravings or pretend they’re not there. You simply watch them come and go like clouds passing in the sky.

Think of your mind like a radio constantly broadcasting worries, doubts, and sugar craving triggers. You can’t switch the radio off, but you can stop tuning in to it.

Over time, as you practise this, sugar cravings begin to lose their grip.

Building New Habits

The best part? You won’t have to do this forever. Defusion is like training wheels on a bicycle. It helps you stay balanced until your new, healthier habits form. Research shows it takes around 66 days to create a new habit. Once you’ve adjusted, your cravings naturally fade, and managing your sugar intake becomes effortless.

Dr Harris uses another great metaphor: imagine a chessboard where your positive thoughts are white pieces and your negative thoughts are black ones. They’re locked in an endless battle. But you don’t have to play the game; you can step back and observe.

That’s the essence of ACT. You don’t have to fight your cravings or thoughts. Just notice them, accept them, and keep moving toward a life that feels good in the long term.

The Takeaway

Beating sugar addiction isn’t just about changing what you eat. It’s about changing how you think. When you stop letting your cravings and emotions run the show, you gain absolute freedom.
