Easy to explain, my body overreacts to what I eat. If I diet strict, I lose weight FAST, one or two bad meals and I spill over to the point I look like a tub of shit, takes me 3 days to get all the water off.
That explains nothing.
How does your body lose weight fast? Is it a result of excessive Protein Kinase A in response to catecholamines? Or do you not use stimulants? Do you drop sodium? Do you cut carbs to nothing?
What about essential fatty acids? Intracellular fat stores?
Spilling over has NOTHING to do with bodyfat.
If you eat low sodium, and no carbs, and then binge on carbs and sodium, OF COURSE you're going to spill over.
And....of course it is going to take roughly a few days for aldosterone and ADH to normalize and remove the water. Espeically if you're hyponatremic and glycogen depleted to begin with.
