Correct me if I am wrong

When entering my daily food intake, the amount of protein, carbs and fat calories to do not add up to what MFP says what the total calories are. One gram of fat contains nine calories and one gram of protein and one carb contain four calories each, so for example: if a certain food item contains 100 calories, the total amount of fat, protein and carb calories should total 100 calories. If it conatined 6 grams of fat (54 calories from fat), that leaves 46 calories available for protein and carbs, let's just say there is 8 grams of carbs (32 calories), that should mean 14 calories should come from protein (3.5 g). At the end of my day my total g of fat (x9), total g from carbs 9x4) and the the total g from protein (x4) should equal to the total of calories consumed, I find that this is not the case. I do this before I enter any calories burned for exercisefor the day. It is one reason why I custom my carb, protein and fat percenatge to 45% carb, 35% protein and 20% fat. All carbs, proteins and fats have the same amount of calories per one gram, just some carbs, proteins and fats are better than others.

Just something to think about.

Fiber is considered a carbohydrate and carbs are 4 calories per gram. Since fiber is not completely digested in the body it is less than 4 calories per gram. As an estimate it is 1-2 calories per gram.
The labeling rule is: If a food has 5 grams of fiber or more, the grams of fiber can be subtracted from the
“Total Carbohydrate” value on food labels.
