Attractiveness is a choice

You decide how attractive you are.
You attractiveness is made of your body language, your tone of voice, your self-esteem, a lot of things. But between 60 and 90% of what you communicate to the outside world is non-verbal, which means it is affected by your personality. 
Attractiveness is a choice and it is half who you are and half how others see it.
How attractive you are depends on what you think of yourself and how you express it. Your body is just a package for the beauty inside. Your sense of humor, talents, kindness, empathy, ability to love.
It is all subjective and relative. Attractiveness doesn't equal attraction. It's perception is driven by hormones like oxytocin and adrenaline and that's why physical attractiveness actually has very little value. 
Unless you want to become a model you will only need it once in your life - when you are looking for a partner to start a family.
Physical attractiveness lasts only for a moment in your life, then it gradually becomes hard work before it goes away for ever. If you build your life around obsession with looks, what happens when it disappears?
Statistically people concerned with their appearance are more stressed and anxious.
Whatever you look like it is the REAL you. You will never feel attractive by comparing yourself to somebody else. There is no other person like this in the world. There is nothing attractive about trying to be or look like somebody else. The world doesn't need another copy but we all need a genuine inspiration.
If you feel you are not beautiful enough you will never feel smart enough, interesting enough, important enough. You will never be enough.
Your low self-esteem is a result of marketing strategy of fashion and beauty industry. You were programmed to feel unattractive.
I have never met a person whose body or face needed plastic surgery, but I know a lot of people who need a lot of work done in other areas - confidence enlargement, self-esteem enhancement, anxiety reduction. 
Remember that aging is a natural part of being a human being.
Body fat is not your enemy BUT you should strive to be the best version of yourself. This means having a healthy body. It is supposed to last your whole life so take good care of it. There is nothing attarctive about diabetes.
You were born attractive in a beautiful body. Your physical appearance is not a mistake to be fixed. There is no such a thing as imperfection because you were created perfect. There are no universal beauty standards because beauty is not seen with eyes but felt with a heart.
You are beautiful to those who matter. And the one who matters most is you.
It is a scientific fact that happiness makes you automatically more attractive. A smile is the best make-up you can wear and we all want you to be beautiful.
Be confident and happy with who you are, that's what attractiveness really is.
