I'm around 10% body fat, and trying to continue leaning out, but I still have a bit of a spare tire (maybe a bike tire) on my stomach going about 2-3 inches below my navel. Some days, my skin will be tight to my muscles and the fat will feel "solid;" on others, it's squishier and I can pull the skin out a couple inches. The changes happen too fast to be fat gain/loss, and I'm not sure what else to call it.
I usually notice these changes (mostly from "solid" to "flabby") when I consume a lot of calories, or a good amount of high-GI carbs (raisins, cranberries). Has anyone else experienced something like this, or seen anything addressing it? Is the change dietary? Am I simply imagining it?
