Renée Zellweger

You undoubtedly know Renée Zellweger in the movie franchise, Bridget Jone’s Diary. But, did you know she had to gain weight for the movie? Unlike Matthew McConaughey and Jason Segel, Zellweger had to have a curvy frame for her character. She followed a specific diet and had to take 4,000 calories a day to add up to her weight. But since the 51-year-old actress also looks after her health, which may compel her to get insurance, she follows a regular diet called the Zone diet to maintain her slim figure.

But compared to the keto diet, the zone diet is composed of 40 percent carbs, 30 percent protein, and 30 percent fat, which is proven effective with Zellweger’s sexy body.

She continually experiments with her current diet together with “The Zone” and “Hamptons and Atkins Diets.”
