Teri Hatcher
Height: 5ft 6in
Weight: 7 stone 6lbs
BMI: 16.5 - underweight
Some sources claim she is battling an eating disorder, but Teri claims she's just careful about what she eats, adding: 'The only thing I'm guilty of is being too athletic and refusing to eat garbage. I eat a lot of fruit'
Victoria Beckham
Height: 5ft 6in
Weight: 7 stone 10lbs
BMI: 17 - underweight
Since her days in the Spice Girls Victoria has shrunk alarmingly, despite having three children. The recommended weight for a woman of Victoria's height is at least 8 stone 3lbs - an increase of 7lbs
Kelly Brook
Height: 5ft 8in
Weight: 8 stone 4lbs
BMI: 17 - underweight
Kelly is famed for her curves, but they aren't enough to stop her from slipping into the underweight category. A woman of Kelly's height should be at least 8 stone 10lbs. Kelly could easily afford an increase of 6lbs
Donna Air
Height: 5ft 9in
Weight: 8 stone
BMI: 16 - underweight
The former Byker Grove actress tries to eat as much organic produce as possible and insists that she eats loads, but the speed with which she regained her figure after the birth of her daughter in 2003 has led to anorexia accusations
Lindsay Lohan
Height: 5ft 6in
Weight: 8 stone
BMI: 18 - underweight
The Mean Girls actress has put her dramatic weight loss down to illness, but one website - www.feedlindsay.com - has already seen 200 of her fans sign a petition begging the star to eat
Nicole Kidman
Height: 5ft 11in
Weight: 8 stone 8lbs
BMI: 16 - underweight
As Nicole's career has soared, her weight has continued to plummet. She is painfully thin, almost to the point of wasting away. The recommended weight for statuesque Nicole is at least 9 stone 7lbs, an increase of almost a stone
Charlize Theron
Height: 5ft 9in
Weight: 8 stone 4lbs
BMI: 17 - underweight
Charlize is proof that appearance is not always reality. She doesn't look underweight, yet her BMI shows her to be too thin by a considerable margin - proof, surely, that it isn't safe to model yourself on any Hollywood star without checking their BMI first
Halle Berry
Height: 5ft 7in
Weight: 8 stone
BMI: 17 - underweight
Like Charlize, Halle has never looked particularly underweight and her weight has never attracted negative publicity, yet her BMI begs to differ. The recommended weight for Halle is at least 8 stone 6lbs
Lara Flynn Boyle
Height: 5ft 4in
Weight: 6 stone 8lbs
BMI: 15 - seriously underweight
She claims she doesn't diet and insists she has porridge for breakfast and eats 'roast beef, peas in mashed potatoes, escargots, caviar, peanut butter and jelly, Pop-Tarts' - but it's difficult to believe her...
Nicole Richie
Height: 5ft 1in
Weight: 6 stone 9lbs
BMI: 17.5 - underweight
The Simple Life star is a shadow of her former self. She claims it is down to a healthy, balanced diet and increased physical activity
I'm not sure if I entirely agree with the theory of BMI's. For me, a few of the celebrities mentioned above, and others that I haven't included in this post, may be below their BMI, however, they look healthy - and that's most probably what matters the most: they look healthy and happy.
At the end of the day, it shouldn't be down to a few numbers that rule your life.
