Will this advice from Dr. Oz make you fat?

Dr. Oz, Oprah's much-loved health guru, recently gave a piece of advice that is raising some eyebrows. The influential doc recommends eating whole grain bread topped with extra virgin olive oil before meals to fill you up and keep you from overeating. Apparently it slows the passage of food.

Over at Celebrity Diet Doctor, they're weighing in on this piece of advice. The verdict? Filling up on something that is high in calories (olive oil) before a meal is no way to lose weight. Instead, fill up on something low in calories, like a piece of fruit or some veggies and you'll not only eat less, but your pre-meal meal won't pack much of a calorie impact.
