I've never heard of this method before.... could you explain it a little more? As for the accessory muscle comment... I'm not sure where this Tracy Anderson person is getting her theories from, but I wouldn't put too much stock in this statement. You have to train a certain way (high volume) or take in more calories than you burn to get bulky. Also, women tend not to get bulky because they don't have the testosterone needed to add enough muscle mass to look 'bulky.'
If you feel that the eating plan is too restrictive, chances are you will not see results because you will not stick with it. I don't know what 'results' she says that you'll have if you follow her plan, but if you stick with a healthy diet and consistent exercise, you will see results in the long run.
