Black coffee

I filled my stomach in NUS. I wondered why people travel so much just for one meal, don't they feel tired? Anyway, I'm not gonna talk about it now.
One minute ago I drank one big cup of black coffee, that's too fantastic that I can't tell my feeling now. It almost turned my stomach. I think I was cheated, bacause I did take notice of the label 'coffee with sugar', why was it still so bitter? To follow what I have been tought that 'treasure the food you are having', I drank up all by holding my breath.
I have heared about the way to keep slim by drinking black coffee and ensure that neither sugar nor milk is added. There might be some chemical staff to kill the fat gines inside your body. That becomes a good idea to make me drink it.
Frankly speaking, the food which turns your stomach is always doing something good to your body, the Chinese medicine is a good example, so is coffee.
