It's that simple?

I was watching Jamie Kaufmans AMA on natural remedies and she's mentioned a catch all easy solution is to simply just stop eating at 3pm go to bed at 10p. Do that for a month. The logic being that there will be very low acid to push up against the LES. My friend also suggested combining this with stomach expansion exercises (32oz water and jumping for a min) in the morning to increase the space acid has to move around.

Has anyone tried the fasting she mentioned or stomach expansion?
