Answer:
In my experience in English class, "as a result" gives an impact to what you're trying to say. It gives the reader an idea of what happens in the cause -> effect
Step-by-step explanation:
An example(s) of this would be;
Jughead lied to Jellybean about meddling with her relationship; as a result, Jellybean doesn't trust Jughead anymore.
Archie refused to be with Betty because he felt he wasn't good enough; s a result, Archie lost Betty as his best friend
This could be also useful in this type of way;
I lied to her, and as a result, my mom doesn't know if she can trust me anymore
Hope this helps. <3
