Wellington: Rumour has it that Renee Zellweger maintains her slim and trim figure by eating seaweed.
The Hollywood star is known for having a thin physique and is said to have recently started munching on the salty snack in a bid to prevent weight gain.
Not just that. Evidently, the star has cut out all dairy products from her diet.
"She just munches on seaweed all the time. And she is convinced that dairy in even the tiniest amount will cause her to gain weight, so she avoids it," a news website quoted a source as telling Closer magazine.
Renée reportedly follows a macrobiotic diet, which includes fish, vegetables and rice. The 41-year-old is so strict about what she eats that her boyfriend Bradley Cooper finds it difficult to buy food when they are together.
"When they go food shopping Renée reads every ingredient on anything they buy. She doesn`t even like toothpaste that contains dairy," added the source.
"Brad understands actresses need to diet for the job. She spends two hours a day working out with her trainer."
