Okay people . . .
So have you ever wondered . . . just how many "calories" we actually "burn" each day???
Well, guess what???
Many of us "think" . . . we "burn" . . . way MORE calories . . . than we "actually" do.
So let's take today . . . and figure out the "REAL" truth of it.

And the average adult "man" . . . expends roughly 2000 - 3000 calories per day
And the average person will "BURN" about 1800 calories per day "WITHOUT" exercise.
Got it so far???
Okay . . . so here's the deal . . .
