I noticed that some nutrition labels don't quite add up. The grams of carbs * 4 + grams of protein * 4 + grams of fat * 9 doesn't always equal the total number of calories. After reading a few articles, I learned that food manufacturers are allowed to round off numbers, which would account for the discrepancies. The article also mentioned a couple other sources of error.

Do you guys just enter the info into fitday exactly as it is on the label, or do you always follow the 4/4/9 rule, even if it doesn't add up to the total number of cals on the label?

usually if the numbers don't add up to the number of calories, fitday will tell you about what it should be.

Yeah but even fitday allows a margin of error. It doesn't strictly adhere to the cals = (carbs * 4) + (fats * 9) + (protein * 4) rule.

.5 of anything can be rounded down. Thats why most labels say 0g of trans fat, but then in the ingrediants you see Partially hydronated oil. So each serving has .5g of Trans fat. Same goes for CHO/PRO grams, thats why the cals can be off sometimes.
