Fat to Fit to Fat and back to fit.

Hope everyone is having a great day. This post is actually for the guys mainly but woman you are more than happy to indulge in this as well. I am a bigger guy, at one point pushed close if not above 300lbs. Over the last few years I had lost most of it and then gained most of it right back. I am currently at 238lbs but have a goal of 165-175lbs. The question is has any one accomplished this and looked ripped after the transformation, without loose skin etc. I am very confident that I will get there, the transformation I have seen in myself over the last few months is nice but I wonder about my gut, will it ever be able to hold a six pack etc, or will there be loose skin. Anyone willing to help please do so, thank you all in advance.
