I acquired a client when a dietitian left Cooper Clinic where I worked. Joyce was awesome. Ate healthy, lots of fruits and veggies, kept a food log. But weight loss had stalled. She had already lost a significant amount of weight and we figured she just hit a plateau. Plateaus can last weeks or months. In reviewing her food journal Joyce had written one cup of Kashi GoLean cereal for breakfast and a snack was one tablespoon of peanut butter with an apple. I asked Joyce if she measured the cereal and peanut butter. No, she used to but got away from the habit. I asked her to measure everything for the next two weeks. Be honest. Two weeks later she was down three pounds. Her eyes had deceived her. It happens. A lot.
