Benefits of a fruit diet or fruit fast.

Good evening gang! I wanna learn the benefits of a fruit diet and how it heals the human body. Could all red fruits help heal the body from all sicknesses and stuff lake that. We know that all watermelons, cantalopes, grapes and others are water laden and which ones will last my hydration to the next day without my pee going all yellow or darker? Please let me know if there are any fruits or best ones to keep fed and well daily. Thanks.

I am curious about this type of diet because I have a friend who has used it for years.
He cannot explain it clearly.
What are the perceived benefits of it?

Considering that a Glass of 100% Fruit juice has almost the same amount Kcal than a can of Coke I doubt that this is a diet.

Sure you take lots of vitamins and other minerals in and it's sure better than some chemically made stuff.

When I watch my wife eating every 2-3 hrs her Thai Food without adding weight, I guess that's the right way.
From all a little bit, not only fruits.

We are born omnivores hence the body lives on hunting and gathering...

I have the feeling that the best rule for a diet is: "If it tastes good, spit it out"

Many of my meals have been fruit only.

Here is an article about the Fruitarian Diet:

Vegetables, dried fruits, nuts, and seeds can also be eaten in moderation.

I have now and then eaten mainly fruit. Earlier in the fall, I was eating mostly applesauce (boiled) through the day, and yesterday ate just raw mustard greens and crabapples and have been eating mainly crabapples since Tuesday, though going back to sourdough crepes this evening. I notice that the apples and crabapples have the virtues of being nutritionally dense and a very light food on the digestion, the result being a sense of energy and concentration of mind.

For me it is as much as anything a practice of gratitude and locavory, of eating what the land gives. I have tried growing grain but it seems as if the land doesn’t want to grow grain! Someone or another always chomps the grasses before they are ripe. Though I’ve been wanting to get to harvesting the lamb’s quarters. But fruit grows so easily, is easy to gather and process (if necessary) and usually is a perennial crop. And they taste good and you can eat them off the tree or bush, unlike nuts, pot herbs, grains, and some roots. And for that, focusing on fruit as staple foods while they are in season seems a very practical way to get more of your food foraged or grown yourself. There also tend to be so many apples some years that you can store up large quantities of dried apple slices, which are good food and a good way of using more bitter apples, as the flavor becomes sweeter with drying.
