Cameron Diaz watches her own diet

Diaz keeps a check on her food habits and favours an `upside down` diet.

London: Hollywood star Cameron Diaz may be envied for her naturally slim and lean figure but the actress herself keeps a check on her food habits and favours an `upside down` diet.

The 38-year-old blonde beauty has a balanced meal plan but follows an upside down diet by consuming carbohydrates in the morning and proteins and vegetables in the evening, a daily reported. "Her diet is an upside-down one where you have your carbs at the beginning of the day then taper off, so in the evening you just eat protein and vegetables. She`ll eat junk food if she feels like it but if she fancies a burger, she`ll just have a few bites," Diaz`s trainer Teddy Bass said. The `Charlie`s Angels` star occasionally digs in her favourite calorific treats and exercises with her trainer several times a week to maintain her `lean and strong` shape. "Cameron has good genes but she makes working out a priority, so we train as often as we can. Depending on her schedule, we`ll do 45 minutes of Pilates or if she has 90 minutes we`ll do half weights and half Pilates and flexibility work. Cameron loves having a lean, strong body rather than a curvy figure," he added. PTI
