That's correct. I simply assisted people with the most popular diets around at the time. It was orginally turn-key ebook website that I bought on Ebay for $4.99 and I modified it for adding the height and weight so I give it personalization and to up sale nutritional products as well.
A little tip, copying fad diets doesn't make a great trainer or advisor, IMO it shows lack of knowledge by copying someone else's programs. These people already pay a high price for these programs. I personally taylor each program to fit my clients needs along with nutrition that not only helps them drop fat but specific foods that will help help with certain problems they might have.
Fad diets are primarily calorie controlled diets with the appeal that they can eat anything they want (to a certain extent) as long as it's within a certain calorie range, while these people might drop weight, it does little to nothing to boost immune systems nor does it really help the type II diabetic or the person with metabolic syndrome, etc,etc. Most of these people who are told they have to lose weight by their Doctor think they can just go to one of these places, lose weight and thats it. Thats misleading!
