"I'm pretty solid, actually. I'm not, like, 110 pounds," she told Elle. "But I'm probably heading towards that."
Liz Hurley: Eliminate Wine and Coffee, Add Vodka
Model-actress Liz Hurley, 44, also subscribes to the belief that alcohol can add unwanted pounds -- just not all alcohol. To keep her famously slender figure since having son Damian, now 7, she has eliminated wine from her diet but added vodka.
"No, I don't miss having a glass of wine because I've switched to vodka," she was quoted as saying in Britain's Daily Mail. "I don't really like vodka that much, but if I'm at a party, I have a small one with a lot of fizzy water and a huge squeeze of lime. Initially, it's like medicine, but I've got used to it now."
"I'm skeptical," Ayoob said. "Swapping out one alcohol for another is not likely to lead to weight loss."
Hurley has also cut coffee. "I used to drink an awful lot of coffee, but I was told after the age of 40, you have to be careful with coffee and wine. Apparently, that can be one of the reasons older women get bloated around their stomach."
Ayoob said coffee is virtually calorie-free and if anything, it acts more as a diuretic than to cause bloating. Alcohol, on the other hand, can cause bloating in the long run. Regardless, cutting both out will only result in a loss of water weight.
So what does Hurley eat? Soon after the birth of Damian, she revealed to the media that she only ate one meal a day and often went to bed hungry. And last year it was reported that she allows herself just one square of organic chocolate or one tablespoonful of ice cream when she wants a treat.
"Too many times celebrities want to drop weight fast and they don't care how they do it," Ayoob said. "But you want to spread out your calories. Otherwise, you're going to slow your metabolism."
Gwyneth Paltrow: Cleansing
"I need to lose a few pounds of holiday excess," she wrote. "Anyone else? I like to do fasts and detoxes a couple of times during the year, the most hardcore one being the Master Cleanse I did last spring. It was not what you would characterize as pretty. Or easy. It did work, however."
The master cleanse, which Beyoncé claimed helped her lose 20 pounds for her "Dream Girls" role, is a trendy liquid diet, also known as the maple syrup diet. Dieters drink a concoction of syrup, lemon juice, water and cayenne pepper.
Paltrow offered on her site a more moderate seven-day detox diet designed by Dr. Alejandro Junger, author of "Clean." It includes chicken, smoothies, fruit and soups and eliminates gluten, dairy, sugar and processed food.
She also offered advice on maintaining regularity.
"If your bowel movements get sluggish, you can accelerate things by drinking half a cup of castor oil or using a mild herbal laxative. Bowel elimination is paramount for correct detoxification," she wrote.
Ayoob is not a big fan of fasts or cleanses. "The calorie deficiency might not be harmful but it's not likely to be all that beneficial either," he said.
He'd prefer to see people eat whole fruits and vegetables rather than turn them into juice and leave behind the pulp and other nutrients. "Your gut is a juicer," he said.
