My only comment is that any quick-fix diet which features strict caloric restriction and increased activity level will net you some weight loss depending on how fat one is at the outset. Most of these crash course diets fail because they're hellishly difficult to follow and don't address any of the underlying issues, or they are just out-and-out scams designed to separate the gullible & desperate from their money. Also, they invariably espouse some BS low-fat, frequent snacking on carby shite. Toss in chronic cardio and you've got most of them pegged.
Hell, if Mark Sisson had called his lifestyle the Primal Diet I'd never even have glanced at it.
That said, this Diet Cure seems to be a little less woo-based because she's quite adamant about ditching processed sugar & wheat. If she threw all those processed vegetable oils under the bus as well she'd have eliminated pretty much everything that comes in a box. Which would be a major dietary improvement for anyone.
