For her transformative role as Fantine in Les Misérables, actress Anne Hathaway followed an extremely restrictive diet that led to significant weight loss. Today, what is Anne Hathaway's diet looks considerably different, shifting towards a more balanced, anti-inflammatory, and mostly plant-based approach to promote long-term health and well-being.

Quick Summary

Anne Hathaway's diet evolved from intense, role-driven regimens to a balanced, plant-forward, anti-inflammatory approach guided by nutrition experts. She focused on antioxidant-rich foods and strategic protein sources, transitioning from strict veganism for better health.

Key Points

Anne Hathaway's Approach: A Tale of Two Diets

Anne Hathaway is known for her versatile acting, and her commitment often extends to her physical transformations for a role. Her dietary history is a compelling narrative, contrasting the extreme and unsustainable methods used for dramatic characters with the balanced, health-focused eating she adopts in her daily life. While her on-screen diets grab headlines, her consistent, balanced lifestyle is the true takeaway for health-conscious fans.

The Extreme Diet for Fantine in Les Misérables

To portray the tuberculosis-stricken Fantine, Hathaway needed to achieve a gaunt and frail appearance, leading to a drastic 25-pound weight loss. This process involved a harsh detoxifying cleanse followed by a restrictive diet of minimal food. For a period, she ate only two thin squares of dried oatmeal paste a day. Later reflecting on the experience, Hathaway admitted it was extreme and unhealthy, a necessary but damaging measure for her craft. This serves as a cautionary example, illustrating the physical and mental toll such drastic measures can take.

The Balanced Diet for Catwoman in The Dark Knight Rises

In preparation for her physically demanding role as Catwoman, Hathaway worked with personal nutrition coach Jackie Keller. Keller designed an almost vegan, anti-inflammatory, high-protein diet to help Hathaway build lean muscle while staying agile. This nutritional plan was a stark contrast to her previous extreme method and prioritized fueling her body for intense stunt training and dance sessions.

Key foods included:

Miso soup
Plant-based proteins like tempeh and seitan
Avocados and almonds for healthy fats
Antioxidant-rich vegetables like yams, carrots, spinach, and leafy greens
Anti-inflammatory spices such as turmeric and ginger
Hydration with plenty of water

Transitioning from Veganism

While her Catwoman diet was nearly vegan, Hathaway later gave up strict veganism after feeling she was not meeting her nutritional needs. Under the advice of dietitians, she reintroduced fish, particularly salmon, into her diet. This allowed her to boost her intake of crucial nutrients like Vitamin B-12, iron, and Omega-3 fatty acids, which can be challenging to obtain solely from plant-based sources. This demonstrates her flexible and mindful approach to health, prioritizing listening to her body over following a rigid eating trend.
