Is there a specific diet Angelina had to follow to maintain her body weight and/or physique for the film?
Our strategy was (can you keep a secret?): she has to have 70% carbohydrates and 30% protein diet with an anaerobic training regime as opposed to aerobic, so she can put muscle on without losing weight. Sticking to four or five meals a day routine as much as possible. Then when she reaches a good body level that we like, we change it to 60%/40% favoring carbs. No junk food, no empty calories, and alcohol only on weekends (now that's hard!).
