I dont want to come to battle field,but I want to get the reward of martyer too. or otherwise I dont want people to see me but I want to climb on elephant and make a lofty safari in the market. If the later is possible complying with former, then 20 kg to take out from the body need a sharp knife using for shawerma. lol. Look the matabolic, and catabolic process of the body, and the proper balanced healthy living need several neutrients, protiens, and minerals that has to be supplied sufficiently enough in every day life throught food alone in normal circumstances.
Even the olive oil, that is to be used in raw, when coocking with it that converted to saturated fati acid giving the way for plaque formation again.

Anyway, the shortest cut I will recommend to you as follows:

avoid all carbos, i mean ricy, foods
use as much as fresh vegitable salads, and fruits

drink as much as cummins fried water frequently, avoid oversleeping. do walking morethan 45 minutes. Fish can be used and an egg white in the morning along with conflex in the non-fat milk.

and keep recording the substential changes daily, because every persons metabolic process cannot be same even if the food is controlled that would eleminate the extra pounds deposited by the body. Anyway Good luck.
