Well, think again. "I don't feel pressure," she tells PEOPLE. "It took nine months to build it, it will take nine months to unbuild it."
But the actress and new mom to 6-month-old daughter Olive is serious about slimming down in a healthy way, so she's been following nutritionist Kimberly Snyder's food plan.
"I designed a diet for Drew that is extremely nutrient dense, but also filling so she doesn't have to feel hungry," says Snyder. "We don't count calories but rather center her diet around whole, alkaline plant foods up until dinner. For lunch and dinner, I make different types of salads for her, followed by an entrée like the ones in my new book Beauty Detox Foods.
"I love Kim's plan because it's so easily applied to real life. I love food and food adventures and when you're on a diet, it's like all the fun ends!" notes Barrymore. "I can't live like that. With Kim's program, I can still enjoy the foods I love but in a healthier way."

One dish Barrymore absolutely loves is Snyder's taco wraps. "They're a great way for Drew to get raw greens into her diet, which are full of minerals such as iron and calcium, omega three fatty acids, and Vitamins A, C, E and K," explains Snyder.
