As I mentioned in my How-To: Track Your Macros post, you’re going to get a wealth of information about your macronutrient intake. But generally people are only going to put in that level of effort if they have a goal to achieve, in terms of physical performance and/or body composition. And the very best goals are S.M.A.R.T goals: specific, measurable, actionable, realistic and timely/time-oriented. So, if you confer with your trusted health professional and decide that a realistic goal for you is to lose 10 lbs in 6 months, then you’ve covered off all of those attributes. But you won’t know whether you’ve achieved that goal unless you MEASURE – in this case, you have to step on that damn scale! You won’t know whether the actions you are taking (the input), such as eating a certain macronutrient ratio/target each day, are working as intended unless you look at the output. And progress is multi-faceted – so the more measurements you take, the more you can see progress and successes in areas you might have otherwise missed by focusing on one measurement exclusively (i.e. only ever looking at the unchanging number on the scale without realizing that you’ve lost several inches by decreasing body fat and increasing lean muscle mass and/or gotten noticeably stronger at back squats).
So, that’s my case for tracking progress. If you’re a believer, follow along!
