If the scale goes up and it ruins your day, this is for you.
Because that number is lying to you more often than you think.
Short term scale changes are rarely body fat.
1kg of body fat is roughly 7,000 calories.
You donāt gain that overnight.
What does change fast is water.
- Carbs store glycogen and glycogen holds water.
- Salty meals increase water retention.
- Hard training causes inflammation and fluid retention.
- Poor sleep and stress raise cortisol which also pulls water into the body.
That alone can shift the scale up by 1 to 3kg in a day or two with zero fat gain.
Hereās where the real damage happens.
When you donāt understand this, the scale starts controlling your behaviour.
One weigh in can kill motivation.
People restrict harder, skip meals, overtrain or give up altogether.
Thatās not discipline.
Thatās misunderstanding physiology.
Fat loss is built by looking at trends, not single weigh ins.
Understand the science and you stop letting a number dictate your mood.
Save this for the next time the scale jumps up for no reason.
