I have come across a diet that appears eminently sensible and feasible; I have not tried it (I need to) but the author is a good friend and has a background both as a family GP and a researcher into all matters concerned with health.
Fast and do penance - and lose weight!
Dr Caroline Shreeve is a lover of the Latin Tridentine Mass and she resides in Wales, not far from me.
Her book is based on a 14 day diet plan that can shed up to 19lbs in the same period - yikes!
What is more, she claims that, on her FBF (Fat Burner Foods) diet you will not feel the pangs of hunger - double yikes!
On the down side you must forgo alcohol (well, what did you expect?) and you must stick to the plan.
Caroline's premise (in one brief sentence) is that some foods actually burn off more calories than they contain.
A portion of Brussels Sprouts, for example, contains, say 50 calories but the body utilises 75 calories purely in the digestion process, some 25 calories are, therefore, effectively "burnt off"
That is a crude example and one would not wish to make sprouts the basis of a daily menu ( look what happened to Richard Dawkins) but Caroline has researched and tested this diet over quite a few years.
Of course, weight loss is also aided by physical exercise or, even, breathing exercises. I would not like to give the impression that it is all down to food type intake.
I suspect that, if the great and the famous came across this diet, Dr Shreeve would rapidly become the food guru of 2013 - meanwhile, if you would like a copy of her book it is available on Amazon (at a very modest price).
