How accurate is the “If every day were like today” number?

I’m eating the same calories everyday yet it changes a lot? And is it accurate?

Are you logging your exercise (or do you have an activity monitor like FitBit synced to your MFP account)? Those predictions are based both on calories consumed and calories expended (and your current weight and reported activity level, so if you keep logging new weights or changing your activity level, that would affect it as well).

Notwithstanding your fluctuations in exercise like the prior poster mentioned, this number is a point-in-time projection based on how closely you stuck to your goal. Speaking from personal experience, when I account for my food meticulously using weighing, scanning etc., and account for my exercise calories using a heart rate monitor, the projections are almost dead accurate. My weight (fat) loss and subsequent muscle gain over the last two years follow the projected curve almost exactly.

i.e. the science works.
