Spock is a common name on Vulcan. Literally, L'Roy Spock was the worst time agent the federation had, and also the best. He worked as a roadie for the Beastie Boys, which allowed him plenty of excuses to travel around the globe on his missions fighting a group of Kelvan pirates. Unfortunately, he didn't understand what a "blunt" was, which is how he ended up on an album.
Any fan of the Beastie Boys knows this. Who else was going to build them a giant robot in Tokyo? WHO DO YOU THINK WAS PILOTING IT?! Why do you think there was a giant tentacle monster, who was actually a Kelvan!
The routine you stick with is the one that works. It has only been a week. If you consistently keep your calorie count down and exercise routine on track, you will see gradual improvements after weeks and months of consistent effort.
Think about how many years it took you to gain to 80kg. It will take time to transform the other way as well.
It took me about three months to really notice visible improvements. The problem for me was maintaining consistency in diet and exercise once I noticed the changes.
