<human>: Can you condense the text into a few key points?

Okay, first of all, sorry if this sounds stupid, I honestly can't find anything online probably due to me not making sense of the google search lol. 

But I started to take weight loss and a healthy lifestyle seriously a little under 3 weeks ago, and so I have been working hard, cutting out all soda and junk food from my life, managing my daily intake of calories carefully and exercising daily 7 days a week. When I started I was around 118.5kg give or take (I didnt own a scale the first few days so I could have been more for all I know), and now I checked this morning and I was 112.7kg.

Obviously I am very happy that I am slimming down, but is it happening too fast? I haven't done a HUGE amount of research but I know the basics of weight loss, and I lurk on this sub every day. 

The people I know that lose weight take months to lose a decent amount, and while this is only a tiny bit I've lost, I still feel it's a significant amount for me, so I'm not sure if this is a good or bad thing.
<bot>: Was 118.5kg (261 lbs.) 3 weeks ago, now 112.7kg (248 lbs.). Is this normal to lose weight so quick?
