How Much Coke Zero Can I Drink on Slimming World?

Since Coke Zero is syn free, you can technically drink as much as you like without affecting your syn count.

However, drinking too much can cause bloating and discomfort due to carbonation. It’s also worth remembering that while Coke Zero has no sugar and no calories, it provides no real nutritional benefits either.

• Coke Zero Sugar Vanilla – Syn free.
• Diet Coke Sublime Lime – 0.5 syns per can.
• Diet Coke (regular) – Syn free.
• Diet Coke Strawberry – 0.5 syns per 500ml.

As you can see, most Zero and Diet versions are syn free or very low in syns, while standard Coca-Cola is high in sugar and syns.

Is Coke Zero Good For Your Weight Loss?

Switching from sugary colas to Coke Zero can support weight loss by cutting calories and reducing sugar intake.
