How to get super skinny legs?

It can be genetic. I'm apple shaped and my legs are thin. But when I gain weight it all goes to my midsection which sucks.

if you get your upper body bigger then your lower body might look smaller

Are the females in your family similarly shaped? If so, then you need to face facts that you will probably never get "super skinny legs". You can't spot-reduce. In order to reduce leg fat, you need to reduce overall body fat. That requires a calorie deficit, and exercise.

OP's profile says male

Male or female, just please don't. -.- Your bones will thank you later in life that you have muscle supporting them.

Im not sure about genetic, but genetic can be change too some how.
Also, i can diet, eat nothing, and i lose 0 weight. No lose weight at all.
I just look bad when i have thighs big, while im a smaller.
Yes, im male. 19 years.

Uhhhh, are you talking surgery to get around genetics? Not sure how else genetics is going to be gotten around. Unless you are looking to get bitten by a mutant spider or fall into a vat of secret ooze.

I've never never heard a man want skinny legs but to each his own.
It's very easy to have extremely skinny legs. Start marathon training. Just look at professional long distance runners, their legs are strong healthy and thin at the same time.
So the key to your need for bird legs is to get out and run as much as possible. If I were you I'd even start a training program and start prepping for races in the near future

eat more and build up the rest of your body, then your thighs won't look out of proportion any more

what's your current height and weight? Because the way you're talking is quite worrying, to be honest. You say you can "diet, eat nothing" and not lose weight.... that really, sounds worrying (the fact that you've even tried eating nothing, I mean). Plus you want "super skinny" legs and you're comparing yourself to people whose "legs are thinner than arms" (like that's a good thing)....

I think I remember you making a post like this awhile back? People gave you very similar (and very good) advice.

I think you'll find that building up your upper body will really make a difference. Your upper body will then make your legs look much slimmer in comparison. Muscle is the one thing that you can work on that will dramatically alter your physique, body fat and bones pretty much decide what they want to do and where they want to go. It's okay if you have a preference for a certain type of look, but you have to know when to be realistic and work with what you've got. If you have a bad body image, in the end there is probably no amount of weight that you can lose or exercise you can do that will make you feel satisfied about your appearance. It's just as important to work on the inside as well as the outside in order to truly be happy with yourself. Best of luck to you lamb.
