ENJOYING A SMOOCH 

Maybe you haven't spent significant amounts of time kissing since you were a teenager, and these days you'd rather sleep than smooch. But if passion for your partner isn't enough motivation, consider the fact that kissing and hugging can take inches off your waistline. 

If it's really passionate, according to health expert Professor Bryant Stamford of Hanover College, Indiana, a good snog can burn up to two calories a minute. 

So it might be worth greeting your partner with more than the usual brief, peck on the cheek. 

Calories burned per hour: Up to 120

Equivalent exercise: A 20 minute run 

TRYING ON CLOTHES 

Carting armfuls of clothes in and out of the changing room, struggling into tight polo necks and out of pencil skirts, marching determinedly from one shop to the next and back again - it's just as exhausting as a trip to the gym and, hurrah, just as good for you. 

According to a recent survey by Debenhams, the average woman burns 385 calories looking for the perfect outfit, taking an average of 7,305 steps. 

Calories burned per hour: Up to 130 

Equivalent exercise: 20 push-ups 

COOKING DINNER 

You probably do it every night without thinking about it. 

And while shoving a ready meal in the microwave won't burn much off, an hour's chopping, lifting, stirring and blending will give you a decent mini-workout, plus the satisfaction that you've earned the meal you're about to eat. 

Calories burned per hour: 150 to 240 

Equivalent exercise: A half-hour jog 

A SUPERMARKET DASH 

Just doing the weekly shop can burn calories faster than Jessica Ennis-Hill can say ‘heptathlon'. 

As your trolley fills up, you're effectively doing resistance training, firming up arms, legs and torso. Piling your trolley with heavy items first - tins, bottles and potatoes - intensifies the workout. 

Calories burned per hour: Up to 200 with a heavy shop 

Equivalent exercise: 40 minutes of badminton 

A LONG, HOT BATH 

Sinking gently into a hot bath is all about relaxing and singing along to Radio 2, not dieting, surely? 

Not so: a Loughborough University study revealed that a steamy bath of 40c can melt away 140 calories (that's a significant 7 percent of a daily allowance of 2,000), and that sitting in one for an hour causes an 80 percent increase in energy expenditure, lowering blood glucose levels as a result. 

Calories burned per hour: Up to 140 

Equivalent exercise: 15 minutes' vigorous swimming 

HAVING A GOOD LAUGH 

It's hard to believe that sitting in the cinema watching the Ab Fab movie could do you as much good as a post-work circuit of the gym, but laughter is a full-body experience that can leave you as exhausted as a treadmill session. 

Research from Vanderbilt University, Nashville, published in the International Journal of Obesity, found that just 15 minutes of good, hard laughing a day will burn up to 40 calories - enough to drop 4 lb of excess weight a year.

Try laughing little and often, whether it's during a phone call with your best friend, or watching a DVD of your favourite comedian.
