Renée Zellweger
Renée Zellweger is best known for playing the titular character in the Bridget Jones Diary movies. Although most people remember her as the chubby, curvaceous woman she portrays in those movies, Zellweger had to actually gain weight to become that way by eating 4000 calories per day!
The 50-year old actress is health-conscious and therefore follows the “Zone diet” in her day-to-day life. In contrast to a keto diet, the zone diet consists of 40% carbs, 30% protein, and 30% fat. Not all diets work for everyone, but this one clearly suits Renée Zellweger – and her fit body is proof enough of that!
