You'd be really surprised - fruits contain a lot of sugar. Dried fruit and fruit juices (which many people think of as "healthy") can zip you past sugar quotas in a hurry.
Honestly, I think it's probably just easiest to limit carb intake overall. Don't bother with the nonsense about subtracting fiber and all that, just set your carbohydrate goals for the day and stay under that. Sugar-heavy foods tend to get naturally eliminated in such a routine because the calorie-to-satiation ratio sucks.
Yes, these are deceptive. You're typically getting all of the sugar, but none of the fiber along with it that slows digestion (along with other benefits). Eating an apple and drinking apple juice are very different in terms of sugar content and the resultant insulin spike.
That said, I doubt anyone has ever experienced negative health effects from eating too many apples.
I experienced "negative health effects" after eating in my childhood about 8 kilos of apples within 24 hours. My parents even considered to call an emergency.
I was alone at home and there was a full bucket of tasty apples that our relatives brought from their garden. As a lazy teenager I decided to feed on those rather than prepare food.
And consider that if one just eats 3 apples per hour, than in 16 hours that gives 48.
That's an apple every half hour, or every twenty minutes if he slept eight hours. I've kept that pace too for hours while coding. Much better to stuff on apples than Cheetos.
Why wouldn't fruit juices contain fiber? Say I put an apple in my mixer grinder, add some water, grind and mix to create apple juice, what part of this mixing and grinding process would get rid of the fiber?
As far as I understand, the fiber should still stay in the juice because I did nothing to take the fiber out of this mixture.
poster above is assuming the consumption of store-bought juice, which is highly filtered and usually from concentrate. not many people have the time or equipment to juice apples themselves.
I know, but given that people trying to lose weight generally have a problem overeating carbs, "giving yourself credit" for fiber carbs overcomplicates tracking and most people tend to underestimate digestable carbs taken in, so counting fiber against your quota can help correct for that error. Trying to "game" your carb intake by padding with fiber will work for the ultra-disciplined, but will probably just result in a false sense of intake levels for most people.
Studies have been done on this, for some reason, whole fruit sugar is immune to the negative effects of sugar. The mechanism isn't entirely known though and doesn't apply to dry fruits.
