Hi Fonty!
I was just about to ask this question when I saw this thread! I will give your method a try. It kinda does make sense that the body will digest the loose skin when it is not needed. I saw this article called "the myth of loose skin" a few weeks ago and wasn't sure what to think.
I lost 30Kg in around 5 months, waist down from 46 inches to 36 inches, and noticed the start of loose skin around my navel, so I put the brakes on a bit. During my period of healthy eating after that, I noticed the skin tightening up a little, as you might expect. So for my remaining 24Kg, I will probably keep on track, my target overall is around a kilo a week.
I will report my experience during the forthcoming weeks. Cheers for the info.
