Hilary Duff recently admitted she's a fan and follower of Gwyneth Paltrow's "starvation diet." Paltrow, 50, made headlines earlier this year when she revealed controversial wellness tips, which included intermittent fasting followed by bone broth meals.  "I know Gwyneth is in trouble for saying this, but sometimes I try to just drink coffee in the morning and starve off my hunger," Duff said during an interview on Molly Sims' "Lipstick on the Rim" podcast.

The "How I Met Your Father" actress isn't the only Hollywood star to go to extremes and maintain a strict routine. Ashton Kutcher once ate nothing but fruit to get into character for a role, while Tom Brady is known to stay away from nightshades – flowering plants (think tomatoes and strawberries) which may cause inflammatory issues.

Jenn Zerling, nutrition counselor, author and CEO of JZ Fitness, told Fox News Digital that trendy diets could have a negative impact on both mental and physical health.  "Fad diets are very short-lived and provide for an emotional rollercoaster," she said. "For some, it causes eating disorders and poor body image.

In the thousands of cases I've managed, people have tried every diet under the sun and everyone wants something that will allow them to eat the foods they enjoy, while losing weight and feeling great.This is possible when people open up to learn about their body " Hilary Duff revealed that food is on her mind from the moment her feet hit the floor in the morning.  "I wake up really hungry," the mother-of-three said.
