Why does google chrome makes my Mac hot and increases CPU, GPU, or RAM usage? Here's the solution

The problem of Google Chrome Helper high CPU usage resulting in mac overheating begins back in 2019 when someone complained that:

I have several chrome windows open at a time and all the google chrome helper processes are using too much memory. How can I disable these from starting? All the instructions I’ve found seem to be for older versions of chrome.

At that time Google released Chrome version 74.0.3729.169 to fix Chrome helper high CPU and memory usage problem. After a long forum discussion, the problem still persists in 2020.

Because disabling Chrome through Preferences > Settings > Show advanced settings > Content settings, doesn’t work in the latest Chrome version of mac. That’s why users are still asking the question.

I’m on MacBook Pro 2017 and every now and then (more often lately), when I have Google Chrome open,  Google Helper (renderer and GPU) is hogging all the CPU processing power and the fan starts off rapidly. Any ideas on how I avoid this?
