Few things are more refreshing on a summer's day than a cold drink on a hot patio. But alcohol is normally a no-no for dieters. Simply put, they're full of empty calories, particularly if you fancy sweet cocktails.

eDiets recently put together a list of sweet-but-not-sinful summer cocktails that you can enjoy without packing on too many calories. On their list of healthy drinks:

• Strawberry Lemonade Martini
• Berry Blast Spritzer
• Less Guilt Margarita
• Summer Breeze Punch
  

What's your favorite summertime drink? Mine is a low-cal Mojito, made with one part white rum, two parts club soda, flavoured with lime, mint and just a touch of sweetener.
