Dr. L: It seems like every month brings us the latest, greatest diet book. Why contribute to the glut? Kathie: Believe me, I’m as tired of these magic formula for losing weight as anybody: “eat this number of calories or this ratio of carbs/fats/protein for Phase 1, then for Phase 2…” Almost nobody can follow these formulas for very long. Writing The Swift Diet was for me a chance to celebrate the importance of healthy whole foods, especially vegetables, fruits and legumes. I’m translating the nutritional science onto the plate.
