Hi I'm 61 y/o and a colleague of mine had vsg a couple of yrs ago she is 50 something. She has mentor me thru this process. I can say her experience, which motivates me is remembering when post-op commence is EXERCISE and keep to your protein, and low carb intake. Yes there's loose skin, especially if you had it before you began to lose weight, but as you build muscle overtime, you can reduce it to a minimal degree. The amount of loose skin is dependent upon, as you may know, the amount of skin elasticity remaining. So for me, I expect to have an amount I may have to dress up (LOL). My colleague is a "beast" when it comes to exercise and she looks amazing, also her diet is vegan base. However, as have been commented, you are going to be so happy with your weight reduction, and when you stall be glad because you can use that to build muscle, and reduce fat. to get ahead of the loose skin, possibly If you loose fat quickly, you will gain loose skin quickly. Thirty something! Girl you're a babe. You are going to look magnificent.
