well , I will tell ya something from my own expirience , when I was 18 years old , my weight was around 140 kg , after something like 7 months I was around 80 kg , it`s about 60 kg less in 7 months , the secret is : stop eating damn !! just cut off your ration x5 , eat a bit once in 2 days , it`s will be hard period , but you will see the results right away.
