I've always used myfitnesspal to track my calories and protein/fat macros since its easy to use, and i always use the usda food entries for tracking. Going by faith I've always accepted usda breakdowns to be a 100% accurate, but im finally taking a look at the calorie v macro count and lots of foods don't match. For example Oat Bran, raw has 17.3p/66.2c/7.03f per 100g which is 397.3 by macro but the calories listed are only 246. Still doesn't fit if you subtract fiber which is 15.4g. Any explanation for this? Maybe i need to switch entirely to macro counting lol

Myfitnesspal uses both raw database entries and user-entries. Anything with a * by it in the database was entered by some random member, and these tend to be more prone to inaccuracy.
The ones that do not have a * by them are standard MFP entries (presumably by the people who run MFP) and in my experience these tend to be accurate.Training log: http://forum.bodybuilding.com/showthread.php?t=160275721&pagenumber=

Yea i just took the macro breakdown that usda gave me for my generic oat bran ( i buy bulk, so no nutrition label) and used the 4 kcal per g of pro/ch and 9 per g of fat. The numbers definitely don't match the kcal that the usda site gave me. I calculated 397 kcals but they said 246, im just questioning my calculations compared to a governement site that uses bomb calorimeters to determine everything :P
