As a personal trainer, I spend a lot of time discussing food choices to assist those clients trying to lose weight. I can't follow people around, looking in the their cupboards and refrigerators, but I can give some basic guidelines that most experts would agree are the basis for clean, healthy eating. My hero, Dr. Oz, discusses many of the same principals on his show. Most health and fitness industry experts would agree that in order to lose and maintain a healthy body weight, 75% of your effort should be focused on your diet, while the remaining 25% is efforts of your workout. This means, you just can't just "work yourself out" to skinny and healthy!
