> its also worth noting that fruit is sugar water. its 98-99% water + 2% sugar and fiber

Oranges, apples, etc are only 85% water. Grapes 80%. The rest is fiber and is likely why your body tells you to stop eating them. Two and a half apples is a lot less appealing than a can of soda (actual sugar water).

The whole percent water thing is completely meaningless though, human brains are 85% water and babies are 80%.

The proportion of water is certainly not meaningless when considering the expected caloric intake of a food administered ad libitum. Satiety is partially controlled by stretch receptors in the gut lining and common sense will tell you it's much harder to consume the same amount of calories from a 2g/100mL sugar solution as from a 10g/100mL solution.

ah, i grossly over estimated the % water in those fruits. interestingly though, fruit juices fall in the 80-90% range I just read.

Hm. I've heard lots of different angles on not eating fruit but never got these numbers. Thanks!

And the sugar is the wrong one - fructose which is metabolized mainly by the liver whereas glucose is used by all cells in the body.
