Wherever you are, don’t be without these weight-loss weapons

Journal – Plan your workouts and meals and write down every bite you eat. This will keep you honest, and can help you recognise things that trip you up.

Water – Fluids can do wonders for your waistline. A recent study found that after people drank 500ml of water, their metabolic rates increased by 30 per cent within 10 minutes, peaking 40 minutes later.

Cash - (Bear with us here…) In a recent study by Visa, people who pay for food by credit card were found to spend 30 per cent more than those who paid with cash.
