My scale was soooo naughty it changed from zero'd out to starting at 2 pounds... changed all by it self. Bugger!!! lol Yes, scales lie, lol Perhaps monitor using a tape measure. I used to measure my lower thigh, right at a mole, same place every time. Now it's how my pants fit when I FIRST put them on.

Keep going with that food journal.... our bodies adapt to ketosis over time and what started as an initial major shedding of pounds due to water loss, and some fat loss, and ketone loss, the ketones become part of our energy usage when the body is keto adapted.

Initially we pee out the ketones, then we are able to use them. Less fat is mobilized to need our energy needs. Perhaps this is part of the slow down.....
