I think this is a realistic approach. When I chose my goal weight, I selected the weight where I felt most comfortable when I was in good shape and physically fit without the extras that I started carrying around later. I've been hovering around goal weight for a while now, so it wasn't unrealistic, but I also no longer sweat the typical ups and downs we experience, as long as I feel healthy and energetic. I've been fortunate to maintain a weight just above my goal for several years, but that's due to being rigorously consistent with my WOE. It's really the only way.
