People in parts of Africa and poor countrys never eat?

yet everyone is still alive. So how come when people post things like "I'm not going to eat for a week,etc etc.." people freak out and say "DO NOT DO IT, YOU WILL BE DEAD OR IN THE HOSPITAL,etc etc" when that isn't true. Those kids in Africa are certainly not healthy considering they starve and never eat..but they aren't DEAD. So one CAN survive with hardly any food?
And another thing I wonder, those religions like Muslim or Buddhists or something that FAST and Do not eat for 40 days or more..are alive. My guess is that their strong faith towards their religion is what keeps them alive, so if someone has SUCH a strong faith and passion towards becoming skinny, wouldn't they're faith get them through not eating at all?

I don't know, some things just do not make sense to me sometimes and I start to wonder lol.

Give me your opinions or the answer (if there is one).
Don't be mean or rude, just have a discussion with me, thanks xoxo

I have no idea why they say that. The human body can last a long time without food. Also, I wanted to clear up what you said about Muslims fasting:

When fasting, Muslims don't go 40 whole days without eating. They just can't eat most of the day, from sunrise to sunset. Between sunrise and sunset, during the fasting days, they can eat as much as they like.

I'm not recommending it, but starvation is a good way to lose weight. Even if you DO eat just a little bit of food, you can still dramatically lose weight. During the Holocaust, Jews got very little food, but they did at least get a LITTLE bit. If you see pictures of those people in concentration camps, you can see they were just as skinny as those starving African kids.
