Morbidly A Beast:
It’s basically all your skin elasticity. Sometimes you gain sometimes you lose causing your skin to loosens. This happens in bigger people you just gain/lose over a long period of time. Sometimes you stretch out your skin so much over such a short period of time the skin stretches to such an extent it “breaks” causing bigger stretch marks, but if you’re losing and gaining a lot your skin is going to have more elasticity
I am certainly softer this gain (when not stuffed silly). My belly seems bigger than when I used to be at this weight. I was pleasantly surprised to see the older stretch marks become highlighted. I am trying to slow things down...but no luck so far. The day started off well. Had a big, healthy breakfast...then wound up at Wendy's for lunch. Sitting at 3000 calories for the day and its just past lunch. Perhaps there will be new stretch marks soon.
