Kelly Osbourne's slimmed down thanks to her plate diet

She's yo-yoed plenty in the past, but now Kelly Osbourne's finally managing to keep the weight off - thanks to the colour of her plates.

Yes, really!

The 27-year-old's following the plate diet, which is based on studies that show people eat up to 20 per cent more when they use a plate that's the same colour as their food, compared to when they use a plate of a contrasting colour.

Kelly was first introduced to the plan by a colleague on her TV show Fashion Police.

It's helped the 5ft 2in star - who was once a size 16 - to slim down to a size 6-8.

A source says: 'Five months after Kelly started the plan the results are there for all to see.

'She thinks it's amazing - she takes her plates everywhere.

'Unlike other fads, Kelly says this diet really does help you lose weight and keep it off.'

It's all to do with the power of illusion.

It's thought a high contrast between the colour of a plate and that of common foods, such as rice or pasta, serves to make you look at the size of your portion and think again.
