I have been counting calories to lose weight. I use food labels and calorie counters to do so. I am happy with my weight loss so far but one thing I'm not understanding is calculating fat, protein and carb calories. At the end of the day I add up my calories. Then I add up the fat, protein, carb (9,4,4) calories to see if they match. They don't. It is always close to 100 calories more when adding the fat, protein, carbs than it is total calories. Just to see what would happen I then subtracted my fiber (counted it at 4 calories a gram) and I can get closer to my calorie total than the other way.
So am I doing something wrong in the calculations or is it that food labels and counters are not true to the actual calories and fat, carb, protein per serving??
