Weight loss and fat loss can be differentiated. Weight loss includes any loss on the scales, be it muscle, fat or even water deprivation. The scales will show this. Whereas fat loss can be much more subtle and sometimes, the scale doesn't show.
The fat cell holds fat tissue, as this cell begins to lose some tissue, the cell is often replaced with water. Why is this? many reasons but here are 3
1) Homeostasis- The bodies attempt to be consistent and stable. It's used to a certain weight, so replacing the fat cell with some water is normal.
2) Stress- This is a huge reason for water retention within a fat cell.
3) Menstrual cycle- This often results in water retention within the fat cell.
What will this feel like?
You will definitely feel leaner, even when retaining water, but the scales may not show it, and even though you've already lost the fat, the scales may not change for a few weeks. Some people find this stressing, but this is why we come back to the first points; Patience and consistency.
The scales will move eventually. Give it time :)
