Cruel to be kind

Fact #1: Most people are shallow to a certain extent.
Fact #2: Looks do matter.
Fact #3: We can't change the above.

Hence, if a friend (who is wonderful in most respects) bemoans why he/she cannot attract a potential bf/gf, and you know that it is due to a physical thing that is WITHIN THEIR CONTROL TO CHANGE AND IMPROVE, what do you do?

(a) Be kind, don't risk hurting them, don't tell them, and continue to see them unsuccessful in these matters and constantly get hurt n deluded and self confidence no good n vulnerable to the scumbags of this earth of which trust me there are many, most of whom have no qualms when it comes to manipulating girls for their own selfish ends.

(b) Tell them in the most gentle way possible that out of love n friendship you dont mind risking incurring their wrath (hope they are mature enough to understand) that their current physical attributes got some things that are not so good but wait these r controllable things so TAKE ACTION (its not the drastic kind like go crash diet go marie france go anorexic) as it will improve your health, energy and vitality anyway. I mean its pointless to be kind n smile n watch them suffer...thats not what being a friend means. Being a friend means you gotta have enough balls to stand up n say lookie here mate, the world isnt perfect, you also dont want a fat ugly smelly dig nose boyfriend right? Similar guys also want a girl who is XXX and hence, just put in a LITTLE bit of effort. Goes a long way. It doesnt mean you're conforming or changing urself.

I hope I'm doing the right thing.
