#54 - The Science of Scale Fluctuations: Why the Scale Can Increase in a Calorie Deficit

You’re in a calorie deficit.

You’re training, hitting steps, and staying consistent.

Then you wake up and the scale's up a couple of pounds.

In this episode, we break down what that number actually represents.

We explain why day to day changes are almost never fat gain or fat loss.

We cover the main drivers of short term fluctuations: glycogen and water, training stress and inflammation, sleep and cortisol, sodium, hydration, and for women, the menstrual cycle.

Then we lay out how to use the scale correctly, how to interpret trends, why we look at three weeks, and when daily weigh ins are not worth the mental cost.
