Boiling everything down yes. It's ways of producing a deficit of calories in vs calories out.
There is a bit more too it when you consider psychology, drug effects, etc etc. But the baseline is if you are eating less than you burn YOU WILL LOSE WEIGHT.
42" jeans(25/01/2013) 40"(28/02/2013) 38"(20/03/2013) 36"(25/05/2013)
Down from 60" waist jeans since June 21st 2012.
Still keeping to my 26" jeans, but they are too tight for comfort. too many tasty things in the US, and over Xmas.
