Not counting surgery, what extreme methods have people employed to
lose weight quickly. Not looking for safe or unsafe, lasting or not,
we are just interested in what people have done that has had immediate
effect.

Apparently maple syrup diet works wonders for some.

define quickly.  

The best way to lose fat healthily is to cut out fat.  Eat grilled
chicken, not fried.  No burgers, no fries, maybe have some baked chips
or cashews if you want some salty food.  Keep non-fat fruit yogurts in
the fridge and when you want that Eddy's at 11pm, eat a yogurt
instead.  The weight loss will start nearly immediately and you'll
feel better too.  You don't have to go hungry or fast - just eliminate
all forms of really fatty foods - including peanut butter, whole milk,
etc.  Read the labels - don't eat anything with more than 3 or 4 grams
of fat per serving.

Most drastic? A liposuction - and no its not surgery anymore with
deployable capsules containing CO2 + ethylene and ofcourse.. an
enormous bed pan.

Columbia Medical Center performed this on a 300 pound 12 year old.. 

not sure of any other examples, but the 12 year old is now 115 pounds.

Eek..never mind above,   -_-; !

Aw, leave it to our former colonial overlords to ruin a perfectly good
diet idea, a maple syrup diet, with all sorts of other nasty stuff.

"...maple and palm syrup, lemon juice, water and cayenne pepper..."

What, British Rail was out of thise Gawd awful sandwiches they sell in
train stations? The ones that seem to have been stored in a damp
morgue for a few weeks before being lorried in from Sudan?

You want to lose weight? Eat only Scottish food that tastes good. The
whole cuisine is based on a dare!
