Huge improvement!
Things changed a whole heck of a lot during the month of April, whatever you were doing seems like it worked. Now I have to go Google “vacuum training” and a waist trainer. I haven’t heard of either but they definitely seem to have a noticeable difference over a very short time frame. I think you might really be on to something!
I’m halfway through a 90lb weight loss attempt, and I expect I’ll be needing these techniques in 3-4 months.
Don’t pull the pics unless you plan to patent the technique and sell it to weight loss clinics. 
If anything, you should keep documenting the hell out of the progress over the coming weeks. Whatever you do, don’t do any dry brushing, because dry brushing enthusiasts will claim that it was really did it. If you solve the loose skin puzzle, you’ll be inducted into the keto knighthood.
There isn’t a single one of us with >100lbs to lose that won’t have to think about strategies to manage it.
