14 Hollywood Celebrities Who Swear by Intermittent Fasting (Their Exact Schedules, Diets & Quotes)

Signature Role: Wolverine in Marvel’s X-Men & Deadpool 3 | Window: 10:00 AM – 6:00 PM

“I feel so much better on it… I haven’t put on nearly the amount of body fat I usually do when bulking, and I have much more energy. It gives your body a rest from digesting food all the time.”

How His Regimen Works:

• The 5,000-Calorie Challenge: To achieve Wolverine’s vascular, heavily muscled frame, Jackman consumed between 4,500 and 5,500 clean calories purely within an 8-hour window (originating from David Zinczenko’s The 8-Hour Diet).
• Fasted Morning Lifting: He performs brutal compound strength workouts (deadlifts, bench presses, weighted pull-ups) early in the morning in a completely fasted state with black coffee.
• Breaking the Fast: His first meal at 10:00 AM consists of 6 poached eggs, smoked salmon, and avocado toast, followed by chicken breast, sweet potatoes, and steamed broccoli at 2:00 PM and 5:45 PM.

“I do intermittent fasting, so there’s no food in the morning. I noticed a big difference in going without solid food for 16 hours. Today, I woke up and had celery juice, followed by black coffee and a workout.”

How Her Regimen Works:

• Zero Solid Breakfast: Aniston avoids traditional high-glycemic morning meals (pastries, cereals) that spike insulin early in the day.
• Fasted Movement: She completes 45 minutes of boxing, yoga, or spin before opening her eating window.
• Clean Break-Fast: Her opening meal at 10:00 AM or 11:00 AM consists of a nutrient-dense green smoothie with collagen peptides, maca powder, spinach, and almond butter, followed by a Mediterranean lunch of grilled salmon and quinoa salad.

“Intermittent fasting has completely changed my life. I’ve been doing it for over five years. Autophagy is the secret — your body starts to clean itself out and recycle damaged cells. It keeps me young, energized, and sharp as a tack.”

How His Regimen Works:

• Late Eating Window: Unlike early eaters, Crews fasts from 10:00 PM until 2:00 PM the following afternoon. This accommodates late-night television tapings and social dinners.
• 6:00 AM Iron Session: He hits the gym at 6:00 AM completely fasted, fueled by black coffee and ice water.
• First Meal: At exactly 2:00 PM, he breaks his fast with a massive protein-packed omelet, bacon, a large leafy green salad, and protein bread.

“I eat between 12pm and 6pm every single day. I do 18-hour fasts now, and I feel so much more energized than when I was eating 8 meals a day starting at 3am. I’m not having to prep meals all day long.”

The Evolution of His Routine:

In 2018, Wahlberg went viral for his punishing schedule that involved waking at 2:30 AM, eating eight times a day, and working out twice. However, in recent interviews with The Wall Street Journal and Men’s Health, Wahlberg revealed he abandoned that exhausting routine in favor of 18:6 intermittent fasting. He still wakes early for prayer and training, but does not touch food until midday.

Known For: John Wick 3, Monster’s Ball | Window: 1:00 PM – 9:00 PM

“I don’t eat a traditional breakfast. I drink a bulletproof coffee or green juice and fast until 1pm or 2pm. It manages my blood sugar, keeps my skin clear, and gives me sustained energy all day without insulin crashes.”

How Her Regimen Works:

• Medical Management: Diagnosed with diabetes at age 22, Berry adopted intermittent fasting and a strict ketogenic lifestyle to manage glucose regulation without insulin dependence.
• Healthy Fats: During the tail end of her morning fast, she sips coffee with MCT oil or grass-fed butter to promote endogenous ketone production.
• Break-Fast: Her opening meal at 2:00 PM features grass-fed ribeye or wild salmon with roasted cauliflower puree and organic greens.

Known For: Thor, Extraction, Limitless | Window: 12:00 PM – 8:00 PM

“Fasting triggers cellular cleanup and keeps inflammation down. In ‘Limitless’, I learned how profound fasting is for brain health, reducing disease risk, and building resilience.”

Key Insights from Dr. Peter Attia & Centr:

In the National Geographic docuseries Limitless, Hemsworth underwent a 4-day prolonged fast under the guidance of longevity expert Dr. Peter Attia. While that was an extreme test, Hemsworth maintains a consistent 16:8 fasting baseline to keep body fat low while maintaining 215+ pounds of lean muscle for Marvel stunts.

Known For: Black Widow, Avengers: Endgame | Window: 12:00 PM – 9:00 PM

“Scarlett fasted for 14 to 15 hours every single day during Avengers filming. She would stop eating around 8:30pm and wouldn’t eat until 11:30am or 12:30pm the following day. It kept her sharp and light on her feet.” — Celebrity Trainer Eric Johnson

Training & Carb Cycling:

Johnson had Johansson cycle high-carb and low-carb days inside her eating window. On heavy Olympic lifting days, she consumed clean carbohydrates (sweet potatoes, white rice) immediately post-workout. On rest days, carbs dropped below 50g to maximize fat oxidation.

Known For: Jimmy Kimmel Live!, Academy Awards Host | Schedule: Fasting Mon & Thu

“On Mondays and Thursdays, I restrict my calories to under 500. Coffee, water, maybe an egg and pickles. It sounds difficult, but it completely reset my appetite. I dropped 25 pounds and kept it off for ten years.”

For individuals who find daily 16-hour fasting inconvenient due to business lunches or family dinners, Kimmel’s approach—the 5:2 intermittent fasting protocol—provides immense flexibility. You create a deep weekly caloric deficit on two non-consecutive days while eating maintenance calories the other five days.

Known For: Chief Hopper in Stranger Things, Red Guardian in Marvel | Drop: 270 lbs ➔ 195 lbs

“I did intermittent fasting where I wouldn’t eat until 1pm or 2pm, paired with long slow distance running. Dropping from 270 lbs to under 200 lbs was brutal, but fasting gave me the clear structure I needed to not overeat.”

Harbour’s transformation between Seasons 3 and 4 of Stranger Things showcased the power of combining 18:6 time-restricted eating with zone-2 aerobic cardio to preserve heart health while depleting visceral fat stores.

Known For: The Kardashians, Founder of Poosh | Window: 11:00 AM – 7:00 PM

“I wouldn’t eat for 14 to 16 hours after dinner. In the morning, I drink warm water with organic apple cider vinegar or matcha green tea. Once a week, I’d do a 24-hour bone broth fast to reset my gut and clear inflammation.”

Kardashian utilizes fasting primarily for digestive comfort and hormonal balance. Her approach aligns with our 14:10 Fasting Plan for Women, which avoids extreme caloric starvation to preserve progesterone and thyroid hormones.
