José´s answer is perfect
Me gustaría volverme más sano andando.
The only confusion would be between "being healthy while walking" and "being healthy by walking."
Since you wrote "..... by walking," a more accurate translation would be "Me gustaría volverme más sano por andar (caminar)."
Me gustaría volverme más sano andando.
