Also, not everyone is obese. For not obese active people, it might not be the best.
Water Fast means only drinking water. Standard terminology. You can verify that with a quick Google search.
1 - 2 month survival estimate is for an ordinary person. If you're obese then you can survive up to a year without food.
For an ordinary person in reasonably good health, a 24 hour water fast only provides health benefits. Up to 3 days of water fasting is beneficial. I wouldn't recommend any longer than that.
The more frequently you fast, the easier it gets. Your body adapts to burning stored fat as fuel and the hormonal hunger triggers become less severe. I've reached the stage where 24 hours is easy.
I'm sorry I'm not born within 200km from you and I don't speak the same dialect -_-'
Clearly entirely my fault…
