A good idea people might concider. Maybe instead of making a no-eating fast (which is good, but isn't used the way its supposed to in todays day by most people.)
What's the proper way?
When Jews used to fast, the main thing on their head wasn't food and hunger (like it is in many cases today). They fasted, and used the time to pray to G-d, learn Torah etc. Same thing tommorow, when people fast on Yom Kippur, please use the time meaningfully. Dont preoccupy your thoughts with food, or whatever and how hungry you feel (which actually makes it worse, and if you think about hunger and how you want to eat, then you will want to eat more and it will hurt). You mind as well use the time productivly- go to shul, pray with some intent at least. Maybe take a little rest during the day if you have to, but overall make it a meaningful.
(By the way I didn't imply that fasting is not good, but what I meant was that making additional fasts, etc. do not necessarily work that great with most people, and it is not for everyone, but still better then nothing- my suggestion was not to speak, so less Lashon Hara would be said, etc. which would be more productive).
