Because GP wanted to eat food without added sugars and complained that he could only snack carrots and hummus. Apples, last I checked, have no added sugar.

Also,your mileage may vary but I'm not sure that fruits should be very high on the list of food to avoid when you're trying to eat healthier. Ketogenic diet, sure, but that's not what this subthread is about. Fruits are good for you. Skip the hotdog instead.
