How long and fast should i swim for?

Question

what is the best way to swim to just get fitter and loose weight.

summer is coming up and i want to loose just a little bit of weight but don't want to not loose enough. i was wondering if there were any people who had like a good work out for me (example: 2 laps slow freestyle then 1 lap of breaststroke etc)

Please no people saying "swim until u nearly drown, swim fast or there is not proper swimming technique or amount blah blah blah" normal people giving normal advice please.

Answer 1

swim freestyle if your not a good swimmer start around 10 laps and add 20% per a week until your at around a 2000 in an hour or so.  

Answer 2

as much as michael phelps.

Answer 3

do a few smooth/slow lengths of every stroke, and then sprint a few at the end.
