What gets measured gets done — the oldest rule in behaviour science
The old saying "what gets measured gets done" is not just office talk. Science shows that simply noting your food and weight shifts how you eat and how much you lose.
You have heard the old saying: what gets measured gets done. People use it in offices and factories. But it fits your body even better. This short read shows why the simple act of noting your food changes how you eat.
What the saying really means for your weight
The phrase is old, but scientists tested it on real people. When you watch and note your own behaviour, the behaviour shifts. This is called self-monitoring. A review of 22 studies found that 'a significant association between self-monitoring and weight loss was consistently found.' In plain words, people who logged their food lost more weight than people who did not. The measuring itself changes the doing. You see the number before you eat, and you pause. That tiny pause is where the magic hides.
Just writing the food down is enough to lose weight.
it dependsit depends — explained simply. Logging helps most when it sits inside a plan with a goal and a little feedback. A review of 24 trials found self-weighing alone did almost nothing, about -0.5 kg. But adding self-weighing to a behaviour programme gave an extra -1.7 kg. So measuring works, yet it needs company: a goal, a check, and a small nudge.
More logging vs less logging, same programme
Make the measuring work for you
The bottom line
The old rule is true. What you measure, you end up doing better. Note your food and your weight, tie them to a goal, and the numbers do half the work for you. Burnie is FREE, so the measuring costs you nothing but a minute.
