Those blessed in the genetic apartment will have a natural increase in overall attractiveness, but good genetics means nothing if one does not use said genetics to their full potential.
Those with poor genetics regarding attractiveness must do all they can in other areas to increase their attractiveness.
I've certainly (to an extent) got the genetic sh*t end of the genetic sh*t stick, but mainly regarding health, not looks.
My diet and lifestyle should combat the psoriasis, dermatitis and type-2 diabetes prevalent in my families gene pool, but naturally I am always pissed at the fact I must suffer the consequences for my ancestors poor diets and lifestyles that is on-going today.
Lookswise I'm average but still feel the jealousy of observing males with more symmetrical faces and more masculine facial features find more success.
I think almost all attractiveness is simply influenced by what is considered biologically healthy and signs of fertility.
You can argue "But fat women were considered attractive in medieval Europe!" but that's because most people in those times were extremely thin due to starvation and nutritional deficiency.
Being overweight in those times was seen as a sign of wealth and even health, as access to enough food would ensure a lack of nutritional deficiency.
Now of course it has gone the opposite direction as most people in most nations have access to health to a point where they can be thin without being underweight or undernourished, and most overweight or obese people today appear to eat the wrong foods anyway resulting and have poor lifestyles resulting in too much sugar, fats, salts, etc. and not enough important nutrients such as vitamins, protein, and fibre.
Keep your chin up and good luck, TGI.
Continue trying to improve yourself and I'm sure you'll see results eventually.
Just don't do it for the sake of attracting women but increasing your own confidence and self-esteem as well and overally being healthier.
