Cut calories without noticing

Try supermarket aerobics

Hate doing the weekly shop? See how quickly you can get it done - and burn extra calories in the process. The rules? ‘Ensure you go up and down every aisle,' says Dean Hodgkin, fitness expert at Ragdale Hall. ‘Pack your own bags and carry them to the car yourself. If you must use a trolley, take it back to the store rather than leaving it at the collection point in the car park.' An hour-long supermarket trip burns around 140 calories - but you could shift another 100 if you really pick up the pace.
