Is it true that instead of fasting by food, u can fast by items. i know this is kind of confusing, look......... a sunday school teacher told my brother that u don't have to fast by food. He said that u can fast by items, for example...... u can fast by not watching tv, or by not talking on the phone, or not using the computer,etc. so is that true, and if yes do u have to still fast by food with the item fasting!?!?!?!?!
