Top Celebrities Who Swear by Intermittent Fasting

Whether it’s for red carpet glamour, peak performance, or simply staying healthy on the go, intermittent fasting has become one of the most talked-about wellness trends in Hollywood and beyond. But this isn’t just another fleeting fad. From Oscar winners to fitness icons, celebrity fasting is on the rise — and for good reason.

In this article, we’ll dive into the famous diets of A-listers who rely on intermittent fasting to feel and look their best. You’ll learn how they structure their fasts, what results they’ve seen, and why this health trend continues to gain traction with stars and everyday folks alike.

Why Are Celebrities Embracing Intermittent Fasting?

There’s no denying the pressure that comes with living in the public eye. Constant travel, photo shoots, performance demands — it all takes a toll. Intermittent fasting offers a flexible, low-maintenance approach to health that helps many stars:

• Maintain steady energy without constant snacking
• Manage weight without restrictive calorie-counting
• Support focus and productivity, especially on set
• Improve digestive health, which is key for skin and sleep quality

Perhaps most appealingly, it works well with unpredictable schedules. You don’t need a fancy meal plan or personal chef—just discipline around when you eat.

Jennifer Aniston: Fasting for Radiant Wellness

A household name for decades, Jennifer Aniston credits her glowing complexion and youthful energy to a mix of self-care rituals, including intermittent fasting.

In multiple interviews, she’s shared that she typically follows a 16:8 routine, where she fasts for 16 hours and eats within an 8-hour window. Her day starts with a bit of celery juice, followed by a late breakfast or light lunch.

She’s also revealed that she often skips solid food until noon, relying instead on hydration — a smart move that supports both digestion and satiety.

“I do intermittent fasting, so there’s no food in the morning. I noticed a big difference in staying clear and energised.” – Jennifer Aniston, Harper’s Bazaar

Hugh Jackman: Wolverine Strength with Time-Restricted Eating

If you’ve ever wondered how Hugh Jackman got ripped for his role as Wolverine, look no further than his dedication to celebrity fasting.

Jackman followed a strict 16:8 intermittent fasting protocol while bulking up for the X-Men films. He consumed his entire day’s calories—sometimes as much as 4,000—within a tight 8-hour window, allowing his body to recover and burn fat during the remaining 16 hours.

This approach helped him:

• Pack on lean muscle
• Maintain definition between film shoots
• Avoid bloating or digestive discomfort

Combined with intense strength training, intermittent fasting gave him the control he needed to sculpt a superhero physique — without sacrificing recovery or mental clarity.

Kourtney Kardashian: Detox, Cleanse, and Control

Wellness influencer and media mogul Kourtney Kardashian is no stranger to trending health strategies. She’s experimented with several diets over the years, but intermittent fasting has become a consistent part of her routine.

Kourtney favours a 14:10 schedule, where she fasts for 14 hours and eats within a 10-hour window. She’s even blogged about extending her fasting window to support detoxes — especially when doing sugar or keto resets.

According to her personal blog, Poosh, she avoids late-night meals and often breaks her fast with avocado smoothies, bone broth, or eggs — foods that are easy on the stomach but rich in nutrients.

Her fasting goals?

Terry Crews: Fitness and Focus on a 16:8 Window

Actor and former NFL player Terry Crews is living proof that intermittent fasting isn’t just for weight loss — it’s about clarity, strength, and lifestyle balance.

Crews swears by a 16:8 intermittent fasting plan, where he consumes all his calories between 2 PM and 10 PM. He drinks amino acids and black coffee in the morning but avoids solid foods until his eating window opens.

Why does this work for him?

• It gives his digestive system a break
• He feels mentally sharper during the day
• He finds it easier to train in a fasted state

His consistent routine, combined with rigorous workouts and mindfulness, keeps him energised both on screen and in the gym.

Gisele Bündchen: Clean Eating with Fasting Principles

Supermodel and wellness advocate Gisele Bündchen doesn’t follow a strict fasting regimen, but her eating philosophy aligns with many intermittent fasting principles.

She tends to stop eating after 6 PM, giving her body plenty of time to digest before sleep. Mornings are reserved for warm water with lemon and herbal tea, keeping her hydrated and helping to ease into the day naturally.

Gisele’s approach is more about rhythmic eating — respecting natural hunger and fullness cues — but she often mirrors a 12 to 14-hour fasting window without calling it that.

Her focus on plant-based meals, clean ingredients, and digestive rest reflects a fasting-informed lifestyle that balances health with intuition.

Benedict Cumberbatch: Biohacking for Performance

When preparing for intense roles, Benedict Cumberbatch reportedly uses intermittent fasting as part of a broader biohacking strategy. While he hasn’t publicly detailed his exact schedule, interviews suggest he leverages fasting and nutrient timing to stay mentally sharp and physically agile.

This is particularly useful for roles like Doctor Strange, where long hours on set demand focus, energy control, and endurance.

For actors who travel frequently and face irregular sleep patterns, intermittent fasting offers:

• Stable energy without constant grazing
• Enhanced mental clarity
• A way to recalibrate digestion after jet lag or stress

If you’re looking to optimise performance without rigid meal plans, understanding how intermittent fasting supports cognitive function could offer valuable insight.

Mindy Kaling: Balanced Fasting and Flexible Wellness

Known for her wit and warmth, Mindy Kaling has shared her approach to wellness in an honest, relatable way. She’s spoken publicly about trying intermittent fasting, but without letting it dominate her life.

Rather than sticking to a rigid plan, Mindy focuses on gentle time-restricted eating, choosing 12:12 or 14:10 windows when her schedule allows.

This balance supports her:

• Busy workdays and parenting
• Desire for food freedom
• Mindful eating without pressure

Mindy’s example reminds us that celebrity fasting isn’t always intense — it can be realistic, adaptable, and deeply human.

The Science Behind the Trend

You might wonder if intermittent fasting is really effective or just another celebrity trend. The evidence says it’s far more than a passing phase.

Clinical studies have shown that intermittent fasting can:

• Reduce insulin resistance and lower blood sugar levels
• Improve fat metabolism and support weight loss
• Enhance cognitive function and memory retention
• Lower markers of inflammation and oxidative stress

Sources like the Harvard School of Public Health and the British Journal of Nutrition continue to publish findings that support fasting’s role in metabolic and neurological health.

And while more long-term research is needed, many experts agree that when done correctly, fasting can be a safe, sustainable health strategy for most people.

What We Can Learn from These Celebrity Diets

While the stars may have personal chefs, nutritionists, and trainers at their disposal, the core principles behind celebrity fasting are surprisingly accessible:

• Choose a fasting window that fits your life — 12:12, 14:10, 16:8, or even alternate-day fasting
• Break your fast with nutrient-dense foods — avoid sugar-laden “cheat meals”
• Stay hydrated — herbal teas, black coffee, lemon water
• Be flexible — especially when life gets busy
• Listen to your body — fasting should feel supportive, not punishing

If you’re new to the idea, start slowly. Try delaying breakfast or setting a “cut-off time” at night. Over time, your body will adjust.
