Drew Barrymore isn’t your typical "Hollywood diet" poster child. She’s the first to tell you she has the genetic makeup of the Pillsbury Doughboy. Honestly, that’s why people love her. When we ask how did drew barrymore lose weight, we aren't looking for a magic pill or a secret surgery. We want to know how a self-proclaimed foodie who "cries for pizza" managed to drop 25 pounds and actually keep it off while hosting a talk show and raising kids.
It wasn't easy.
She calls it "hard AF." She describes herself as "fighting like a lion" to see results. There were no shortcuts, just a very specific, somewhat grueling combination of metabolic science, barre classes, and a "guru" who changed the way she looks at fiber.
The "Santa Clarita" Catalyst
The real shift started with a zombie. Well, a high-functioning real estate agent zombie. When Drew signed on for the Netflix series Santa Clarita Diet, she decided her character, Sheila, needed a physical transformation to match her undead awakening. At the time, Drew was around 145 pounds and felt, in her own words, "naïve and unhappy."
She went to her executive producer, Victor Fresco, with a plan. She wanted to lose 20 pounds over the course of the first season. She wanted to change her eyebrows, her shoes, and her body language. She wanted to look "alive."
Why the "Glowing Green Smoothie" Actually Works
If you follow Drew, you know about Kimberly Snyder. Snyder is the nutritionist behind the "Beauty Detox" movement and the person Drew calls her "guru." The backbone of Drew’s nutritional overhaul was Snyder's Glowing Green Smoothie (GGS).

This isn't just a trendy juice.
It’s a thick, fiber-rich blend of spinach, romaine, celery, apple, pear, and banana. Most celebrities do juice cleanses that strip away the fiber, leaving only sugar. Snyder’s approach is the opposite. By keeping the fiber, Drew was able to stay full while flooding her system with micronutrients.
During filming, Drew’s diet looks roughly like this:
- Morning: Hot water with lemon, followed by 16-25 ounces of the GGS.
- Lunch: A massive "Beauty Detox" salad or a quinoa bowl with sprouted hummus.
- Dinner: Cooked vegetables, lentil soup, and occasionally a small portion of fish or chicken.
Wait, isn't she vegan? Sorta. When she's in "transformation mode," she leans heavily into a plant-based, vegan lifestyle. But she’s realistic. She told Us Weekly that she added protein like fish and chicken back in because she needed the energy. She follows an "80/20" rule—staying disciplined 80% of the time so she can have the fettuccine alfredo she actually craves the other 20%.
The Trainer Who Changed Her Mindset
You can’t talk about how did drew barrymore lose weight without mentioning Marnie Alton. Alton is the founder of M/Body and the woman Drew credits with "healing" her.

They’ve known each other for over 15 years.
Alton’s method isn't about mindlessly lifting heavy weights. It’s a mix of barre, yoga, and dance that focuses on "sculpting, sweating, and stretching." For Drew, the movement had to be about more than just a number on the scale. She struggled with body image her whole life. Alton helped her shift the focus from "how do I look?" to "how strong do I feel?"
During her 25-pound weight loss stint, Drew was working out with Marnie almost every day. It was intense. It was consistent. It was the kind of work that makes your face look thinner and your muscles actually show up for the first time.
Genetics and the "Lion" Mentality
Drew is incredibly vocal about the fact that her body wants to be "heavy." She doesn't have the metabolism of a teenager. After having her two daughters, Olive and Frankie, she noticed her body changed in ways that didn't just "snap back."
"Damn you genetics!" she once posted on Instagram.

She uses this phrase to remind her fans that the "before and after" photos we see on social media are often the result of professional help and immense discipline. She even admitted to using EmSculpt, a non-invasive treatment that uses electromagnetic energy to strengthen core muscles. It’s that level of honesty—admitting she used a "tech boost" alongside her salads—that makes her journey feel human.
The Seven Habits List
Recently, as she approached 50, Drew shared that she relies on a list of seven healthy habits developed with her therapist, Dr. Barry Michels. She keeps this list on a piece of paper that has become so worn she has to retrace the words with a black pen.
When she feels "puffy" or "off-center," she goes back to these basics:
- Prioritizing sleep over late-night scrolling.
- Drinking massive amounts of water.
- Returning to the Glowing Green Smoothie.
- Moving her body for at least 30 minutes.
- Focusing on "happy hormones" by managing stress.
- Eating for blood sugar stability (pairing carbs with fats/proteins).
- Practicing "progress, not perfection."
Actionable Takeaways from Drew's Journey
If you're trying to replicate Drew's results, don't just stop eating. That's not what she did. She changed her internal chemistry.
- Start with Fiber: Stop juicing and start blending. Keep the pulp. The fiber in greens helps stabilize your insulin, which is the "fat-storage" hormone.
- Find Your "Marnie": You don't need a celebrity trainer, but you do need a workout that feels like "therapy for your soul." If you hate the gym, try a dance class or a barre video at home.
- The 80/20 Rule: Don't ban pizza. If you ban your favorite foods, you'll end up crying over a slice like Drew did. Eat clean most of the time so you can enjoy the "emergency" meal when you need it.
- Focus on Blood Sugar: Look at your plate. Is it half vegetables? A quarter protein? A quarter complex carbs? This "Plate Method" is what Drew uses in 2026 to maintain her energy and keep her hormones balanced.
Basically, Drew Barrymore lost weight by stop trying to be "perfect" and starting to be "consistent." It took three months to lose those 25 pounds, but it’s taken years to build the mindset that keeps her healthy today.
