Nix sweet snacks

It’s time to ditch the office biscuit tin, the vending machine at 3pm and your co-worker’s birthday cake, too. Even that ‘nutritious’ energy bar you stashed in your handbag for emergencies has to go (some contain as much sugar as a chocolate bar). It’s an obvious place to start, plus, you’ll slash unnecessary kilojoules while you’re at it.
