This is a simple method I use to write top quality articles quickly and easily.
First go to Ezinearticles dot com.
Then type in a general keyword related to your niche. For example "weight loss".
Hopefully you'll see plenty of articles appear.
Now all you need to do is skim through them and copy and paste a list of the most common points people are bringing up.
WARNING: NEVER copy someone else's work. But taking the general idea of what they're talking about is perfectly fine.
Once you have a list of the main points people talk about in their articles, simply expand on them in your own words.
Add an introduction and a closing paragraph and you're done!
