congrats on all the healthy changes! a growth spurt at 30 seems a bit late in life - but you should ask your doctor abou that. either way your body seems to be responding positively to all the healthy changes! keep it up! and people do look taller when they are leaner - so perhaps that is part of it?
i just turned 30 and seem to be going through a growth spurt is that cause for concern? . i did change up my diet to a mostly vegetarian diet and i stopped drinking soda. i also started exercising regularly and taking a daily vitamin. my diet before was terrible and consisted of mostly junk food and i drank soda about 9 out of every 10 times i drank something. if it helps i also hit puberty kind of late probably around 16 or maybe early 17.
