As a scientific study suggests sleeping in your parents' bed as a child makes you slimmer when you grow up, we look at some of the more weird and wonderful ways to battle the bulge.
Paint your walls blue
Bizarre as it may sound, the colour blue is an appetite suppressant. A study by Dr Val Jones and the Parsons School of Design in New York showed just how colour can affect food consumption. The research team set up three rooms bathed in different colours - red, yellow and blue, in which participants were served identical plates of food. Around 33% fewer snacks were consumed in the blue room, perhaps because we associate blue with mouldy food. You don't have to repaint your walls, of course, but you could try eating off blue plates, or cover your table with a blue tablecloth.
