The author, Julia Havey, has generated publicity for herself lately with her accusations against Coke and their Drink, Choose, Live promotion. She contends that regular Coke, and any non-diet soda products, are the #1 contributor to the obesity epidemic which cause secondary health problems.
If you read her blog (which is co-branded with eDiets) you'll see that she's a big supporter of lawsuits. Suing Coke over the wording of their ads and suing (seemingly) all companies that produce high-calorie foods because I guess it's up to them to decide for us what we'll eat instead of thinking for ourselves.
But back to the book... Havey says in her press release:
It is difficult if not impossible for someone to change every aspect of their lives overnight, as many of the popular diets demand; but anyone can succeed at realizing change if you approach it ONE change at a time. That is what I help the reader do in The Vice Busting Diet, to tackle their worst habits one by one and my approach supports them as they transform from their current lifestyle which supports their excess weight to one that will support improved health and fitness for the rest of their lives.
