This is very good question! Fibres have many advantages. Fibres have probably negative calories also. That means fibres consume some food material in them. Most probably fat is adsorbed with the fibres. Some of this fat is degraded as used as a food by the bacteria in the large intestine. Some of the fat is discarded along with the fibres in the faeces. Fibres also adsorb the toxins, that are present in your food.
No, apples do not have negative calories. They contain calories that provide energy when consumed.
To calculate calories from fiber, it's important to note that fiber itself is not fully digestible and typically contributes minimal calories to the diet. While soluble fiber can provide about 1.5 to 2.5 calories per gram through fermentation in the gut, insoluble fiber generally contributes zero calories. Therefore, when calculating total caloric intake, fiber is often excluded, but if you want to include calories from soluble fiber, you can multiply the grams of soluble fiber by the calorie value (1.5 to 2.5 calories) to estimate its contribution.
Roughage (dietary fiber) is indigestible and does not provide vitamins, calories, starches, protein or fats to your body.
Fiber does not contribute any calories to the human diet, although there are other species that can digest it to obtain calories.
The original fiber one cereal is 60 calories per serving.

Mostly because fiber is a complex structure created by plants, complicated enough that we humans can't digest it, and therefore can't metabolize it for energy. That's why it's so useful for cleaning out our intestines and colon.
