Speed, I do not know what this 12 wk program is (do be aware that the likelihood of long term weight loss is minimal across the various commercial diet plans, and it sounds like this guy Chris Powell is capitalizing on the fact that diets can be successful short term (12 weeks) so he is probably trying to get credit for your initial success, but if you lapse later, he would blame you), but I do realize that this program is a challenge for regular people who are not grieving the loss of their only child, not weaning themselves off hardcore antipsychotics, are not depressed, etc.etc. So be kind to yourself and do not make this program yet another stressor in your life. If you like it - good, if you do not like it - sour grapes.
