First things first: If you dont have great will power - dont even think about going on this diet. Its increadibly boring and very hard. This said: I lost 18lbs during the 16 days of this diet!
The facial analysis is self applied; you look at your face and assess the features according to a "tick list" in the book. Such things as a greasy nose and lined forehead make you say, a type A, while a tendancy to dry skin and a sallow complexion may make you an E, etc. Once you have your "type" you then check what you should be eating and what you should be avoiding, then start the diet.
The diet itself is extremely harsh: You dont starve, but its very spartan and consists mostly of very bland salads (who'd have thought eating nothing but lettuce would make you lose weight huh?! And oddly enough - it seems that chocolate, dairy, red meat and white bread feature on the "bad foods" list of every face type, while fresh fruit, veg and lean white meat feature on everyones "good foods" list... hmmmmm...)
There is also the small matter of the specialist foods, such as quinea, which - as the author claims "are not hard to find" ... THEY ARE IMPOSSIBLE to find in all but the most random health shops! And they aint cheap!
Theres an overlying concern I have after reading this book too: Its claim is that you should eat according to your face type, well the "plan" consists of a 2 day detox (one diet for each face type) then a two week core diet which is the same for everyone... so I cant really see that youre eating for your distinct face type if EVERYONE follows the same diet!?
I would say this is a strange & possibly misleading plan, and ideally - because its nothing more than a posh version of the scarsdale diet, Id like to give it 1 star: But I have to be fair, I lost a huge amount of weight quickly so it does do what it says so it gets a begrudging 3, mainly because of the inaccessibilty of it to most people.
If you want to lose weight for something like a reunion, wedding or holiday, very quickly, I really reccomend it. Just be aware that this is really a diet for those with absolute concrete will-power, access to LARGE health shops, and probably best for those with just a small weight loss target and who want to get there fast. I wouldnt reccomend this diet if you have more than 20lbs to lose as its long term use would be most impractical for all but those on a stars salary, no job or social life and who dont like food. At all.
