Macros or caloriee

What are your goals? If your goals are about weight control (whether that means losing, gaining, or maintaining), tracking calories is the simple, straightforward method. Tracking macros can be a proxy for tracking calories, but it's a little more complicated and requires extra vigilance in logging to make sure database entries are accurate for three different numbers, rather than just calories (then there's the alcohol monkey wrench, which you can't trace as a macro on MFP).
