OK – It does work if you work the program. I lost 4kgs in 3 weeks, which I was pleased about and it made giving up fruit for 2 weeks worth it. Overall though, it is exactly the same price and content as Tony Ferguson with less flavour and more rules. They do keep you full, but then I've found all three of the shake companies I've tried do as long as you are consuming the required amount of water (2lt/day) and eating at designated intervals (6 times a day - funnily enough, I'm not a dessert eater). I have a slow metabolism, so the shake route is good for someone like me to kick start things. However, I've switched to (and will stick with) the Aldi's shakes (Slim & Trim), because they are $1.99/sachet vs $3.25/sachet (Dr Tim and Tony Ferguson) and have relatively the same contents. Nothing that a multivitamin can't cover. (P.S. Neither Tim nor Tony have gotten the soups quite right yet either.) Shakes and bars are convenient. If you follow it you can lose weight and the price isn't outrageous. Those without a huge sweet tooth could do well on this one, but it does take motivation. I loved the weekly visits to my consultant. She kept me motivated through the tough spots, however, she couldn't actually give me much in the way of tips that I didn't already know. Mind you, I've been down the weight loss track before. They tasted like a diet shake and the bars were like chewing on a cow's cud! The shakes actually have EXACTLY the same ingredients as Tony Ferguson, with the exception of being higher in calories and lower in sugar. For those, like me, with more of a sweet tooth than savoury, this stuff is akin to drinking gritty, liquidised chalk.
