By this I mean, not muscle firming up, but the actual stomach shrinking inwards.

The only other time I experienced this was during a 2 week fast - my stomach tightened inwards quite a bit - then when I went back to eating, I ate less & slower . . . otherwise I would have hurt my stomach.

I'm just curious if this is a regular part of ketosis or LCing in general. I consider it to be a great benefit - I'll be able to continue to feel satisfied with less food & feel uncomfortable bulking up on carbs . . . of course, if I were to slip back into high-carb eating, I could force it on my body without much trouble. But if I use it to my advantage, this could end up to be a helpful tool. I've heard about overweight people even having a procedure to sew up part of their stomachs to make them smaller & aid in weight loss!
