Yes it’s possible to eat small amounts of certain fruits (not sure about apples specifically) and not be thrown out of ketosis. When in ketosis I tend to avoid fruit, sometimes I’ll have a small amount of blueberries in a smoothie balanced out with fats from coconut milk, almond butter and chia seeds, plus some fiber (spinach). But I even avoid high-glycemic vegetables, like carrots, when in ketosis.

Generally in calculating their carb/sugar intake people will reduce carbs/sugars by fiber, it’s not exactly scientific but probably works for the most part. I don’t even bother calculating carbs for stuff like spinach, kale, or Broccoli.

Carrots have a high glycemic index, but a low glycemic load. That is, you will rapidly absorb the glucose in them, but the amount of glucose they contain in the first place is low.

Anecdotally, I've never heard anybody complaining about insulin spikes in their continuous glucose monitor from eating carrots.

I never used a blood glucose monitor, but I did use ketone test strips and small amounts of shredded carrots added to a spinach salad would have pretty significant impact on my detectable ketone levels.

I was often surprised by things that knocked me out of ketosis. For example normal serving sizes of whey or casein protein powders (<1g of carbs/no sugar)could.

I’m not hating on carrots or demonizing them, just for my purposes I avoid them and other foods that knocked me out of ketosis or consistently had significant impacts on my detectable ketone levels.
