Cut calories without noticing

Drink ice-cold water

The prospect of dropping ice cubes into your drinking water isn't particularly enticing in winter-time - but it could be worth a go. The reason? ‘Drinking ice-cold water gives your body a little extra calorie-burn because the water needs to be heated up in your tummy,' says personal trainer and sports therapist Joslyn Thompson. ‘It's only 17.5 calories per 16 fl oz - but every little helps!' What's more, ensuring you drink plenty of water can help you feel full-up so you'll be less likely to reach for sugary snacks.
