Two numbers that matter more than the one on your scale
The scale number lags behind your real effort by days of water weight. Your daily deficit and your logging consistency are the two numbers that lead, so they tell you the truth first.
You step on the scale and the number is up. Your heart sinks. But that number is the slowest storyteller in your body. Two other numbers tell you the truth much earlier. Your daily deficit is the cause. Your logging consistency is the behaviour. Watch these two, and the scale will follow.
Number one: your daily deficit (the cause)
Your daily deficit is the calories you ate minus the calories your body used. Burnie works this out for you as food calories minus your BMR plus active calories. A deficit means you used more than you ate, so your body took the rest from stored fat. The old maths rule says about 3500 kcal of deficit loses one pound of body weight, which is about 7700 kcal per kilogram. That is why a small daily deficit adds up slowly and surely. This number is the engine. It tells you what is happening today, not what happened last week.
Number two: your logging consistency (the behaviour)
Consistency means you log your food most days, even if some logs are not perfect. One study watched people for a year. Only the consistent trackers, those who logged on more than 66 percent of days, kept losing weight steadily, about 10 pounds in a year. The people who logged rarely or on and off lost far less. Another study found that logging at least three days a week mattered more than writing down every tiny detail. The lesson is simple. Show up most days. Perfect logs are not the point. Showing up is.
The scale tells you the truth about today's effort.
mostly falseMostly false. The scale moves day to day from water, not fat. In one study of nearly 30 years of daily weigh-ins, day-to-day body mass varied by about 0.53 percent, around 450 mL of water in a 75 kg person. That water swings from salt, stored sugar, and toilet habits. So the scale shows you water first and fat much later. Your deficit and your logging show up first. The scale follows them by a week or more.

The bottom line
The scale is the slowest number in your body. Your daily deficit is the cause, and your logging consistency is the behaviour. These two lead. The scale follows. Watch the two that lead, and the one that lags will take care of itself.
