No water or food is not a diet.
When you really, really want to lose weight in a hurry, it can be tempting to jump on the first fad diet that catches your eye. This is why it’s important to do research and hear opinions on this kind of stuff, because otherwise you end up with dry fasting.
Dry fasting is a “diet” that has gained some notoriety lately on social media sites. Fasting-type diets have been a thing for a while, and there’s nothing inherently wrong with them as long as you still get your important nutrients. Dry fasting, though, requires you to consume neither food nor water for long stretches of time. Let me make it clear from the get-go: this is a terrible idea.
Regular fasting is one thing, but the human body can’t survive without regular hydration. People have claimed that dry fasting can “reset” your kidneys to get better bodily filtration. People who have tried it have taken pictures where they look to be in better shape, but that’s because their bodies are burning up electrolytes like crazy.
When you purposely deprive yourself of water, your body instinctively shifts into crisis mode and begins releasing chemicals and hormones to conserve what little water it has. If you try to go an entire day like that, you’ve got a good chance of developing kidney stones. Any longer, and your life may be at risk.
So if you want to fast to lose weight, by all means, do it. But make sure to drink lots of water while you do it. Human beings are 60% water; take the water out, and you’re less than half a person.
