I actually think Hamilton may have gone through quite a change, physically. When I was at the Belgium GP in 2011 (I won Paddock tickets!), I walked right past him. We're roughly the same height, but I recall noticing that he seemed quite muscular, certainly in comparison with other F1 drivers I saw that day who for the most part are all rather slim (really slim
physically!).
BTW: From the article I linked, there's a direct quote from Hamilton himself who states
"I weigh about 71kg [11st 2lb]. I was never 65kg [10st 3lb]. I was 68kg [10st 10lb] last year but I have put on three kilos since then. The guys have not told me to do that [lose weight].
"I actually want to put on another kilo of muscle! I think Michael [Schumacher] was 78kg [12st 4lb] with all his kit and Adrian Sutil was 82kg [12st 12lb]. I am not going to be 65kg unless I cut my nuts off.”
-- that article is from 2013. Given that he has been in F1 for 6 years at the time of the article, I'll assume that he was lighter in his earlier days, but by the natural progression of age and fitness (muscle is heavier than fat), he probably gained a bit.
Anyway, the point isn't about if Lewis is 66 or 71 - it's about to what degree driver weights are an issue. I think the issue is more of a factor if you have two team-mates which a large(r) weight differential between them. If both drivers are roughly same in height and build, it probably levels out. If you have one who is 10+kg heavier, how do we know that the car is not targeted (not on purpose of course) so that the lighter driver meets the minimum weight perfectly (without ballast), while the heavier one is over it? There are some teams that apparently do struggle to meet the minimum weight of the regulations - are these only some midfield teams like Sauber or is this an issue across the grid?
I think Kubica in the past demonstrated that an advantage can be gained by losing weight to ridiculous levels - at least, he believed so.
