I was watching a great programme last night that documented women from the late 1800's to 1940, 2 things surprised me, there was quite an amount of large women , there were also no women who were as thin as some of the celebs of today, they were what used to be normal sized women who were around a size 10 or 12.
anyway back to the OP, weightloss should be about lifetime changes, not a cabbage soup diet until a couple of stone disappears, I personally think he looks better a bit heavier.
