Calories not important. Type of calories important. Fibre contains calories, but they are locked up in a hard chemical shell that your body cannot crack, and therefore is unaffected by it. So, 200 calories of regular carbs are far more fattening than 200 calories of fibre carbs.
Edit: When I said that the body is unaffected by it, I was referring to the fact that fibre does no trigger the same cascading chemical reaction that other carbs do. No amount of fibre will cause an insulin spike and increased fat storage.
The types of foods (and NNSs) we consume, and the chemical affects they have, are more important than the amount we consume.
- EForEndeavour 3y agoThe reduced availability of food energy from fibre is already accounted for in at least Canada's food labeling rules: https://inspection.canada.ca/food-labels/labelling/industry/nutrition-labelling/elements-within-the-nutrition-facts-table/eng/1613599715710/1613599936553#s4c1 https://inspection.canada.ca/food-labels/labelling/industry/... Energy value of dietary fibre A value of 2 Cal (8 kJ) per gram should be used for the dietary fibre portion of the fibre source. A value of less than 2 Cal (8 kJ) per gram may be used for the dietary fibre content if a specific value is available for the fibre source. Energy value of bran The energy value of the fibre portion of wheat bran is 0.6 Cal (2.5 kJ) / g and the wheat bran itself has an energy value of 2.4 Cal (10 kJ) / g.
- irthomasthomas 3y agoYes, but it is not only the difference in available energy that is important. Fibre, although it is a sugar, does not trigger the same insulin response that other sugars (and NNSs) do.
- gateorade 3y agoThis is largely incorrect, and also not what the person you're replying too is saying. Calorie numbers in food are just a weighted sum of the grams of carbs, fats, and proteins in the food. Each of those groups are assigned a fixed weight based on an estimate of how many usable calories are in a gram of each. The commenter above is talking about how we often ignore the adaptability of the body, and that if you suddenly cut caloric intake by say 300 a day, the body will surprisingly quickly adapt by lowering metabolic rate to compensate. This can be done through the simple modulation of hormones and may also involve the shedding of metabolically expensive tissue, like muscle.
- josephcsible 3y agoI thought nutrition labels already didn't count the calories in fiber that you can't absorb.
