Slower intake rate. Much like your liver can metabolize an oz of alcohol per hour in perpetuity (well, until liver cancer sets in) and you won't even get drunk, but trying to drink 100 oz all at once every 100 hours will promptly kill you. So the theory is slapping your blood and insulin system with the equivalent of 20 apples in a single impulse will mess with your insulin levels and fat storage rates much more than slowly sipping it in, by having chunks of apple take hours if not an entire day to digest. Sipping a glass of apple juice over the course of an entire day would probably be healthier than slamming it in one gulp, however your dentist probably wouldn't approve. Speaking of dentists, scrubbing the flat surfaces of my teeth by grinding carrots for awhile in my mouth should lead to fewer dental issues than soaking my teeth's plaque layer in completely liquid acid and sugar. There's also the fairly obvious issue that given the choice of 100 grams of apple fructose or 50 grams of fructose plus 50 grams of inactive fiber, obviously the raw fruit will provide fewer calories for a given subjective level of fullness. I know I'm eating junk food when I juice, but sometimes its fun and it certainly is tasty, and it never fails to amaze me how it takes half a bag of produce to generate a cup of juice. Most of the calories in that bag are in my cup of juice. A normal snack for me is a couple carrots, but I can turn five pounds of carrot calories into a (very large) cup and slam it. Possibly your body can survive having the liquid sugar of 25 apples slammed into it instantly, every day. Certainly we never evolved to eat that way, so if we can handle it without sickness, its just good luck as opposed to evolutionary pressure. Our ancestors digested a lot of citrus very slowly one piece at a time, there was strong evolutionary pressure to thrive eating a piece of fruit per meal.
