But the reality star appears to have acted upon their advice, showing off her slimmed down body as she posed in a bikini today.
Holly, who was celebrating Memorial Day in Las Vegas, wore a multi-coloured string bikini as she posed for the cameras.

Her hand confidently on her hip, she looked perfectly at ease.
Earlier this year Holly was dealt a blow when producers of her burlesque review Peep Show, ordered her to lose weight.
Holly, who then weighed 115 pounds, was told by producers to lose the 15 pounds she gained when she moved from the Playboy Mansion to Sin City.
The indefatigable blonde said at the time: 'I always thought I looked fine. It was a shock to me when they told me to lose weight. I'm still up in the air over what to do.
'I feel like I changed my eating habits to really healthy; I've lost a few pounds. I'm still getting there and deciding if I even want to lose weight.'

Happily Holly, who has always been proud of her realistic curves, resisted the urge to become a stick insect.
Career-wise it seems it was the right move - the Holly's World reality star has seen her life-after-the Playboy Mansion show do well on E!.
But the impending marriage of her 85-year-old ex-boyfriend has not proved as welcome.

Hugh Hefner is marrying Crystal Harris, 24, despite him repeatedly telling Holly he would never marry again, before she left him in 2008.
His insistence led to her ending their long relationship.
Then last month she split from All Time Low guitarist Jack Barakat, the latest in a line of failed romances.
