Fonts slow down website speed

Hi, I can see in test results that fonts are heavy on my website. I have GZIP compression enabled on NGINX. But, still they are far more heavier.

I don’t have cache enabled. But, I have heard about NGINX reverse proxy cache stuffs.

I also see doubleclick content breakdown on No. 30. However, I don’t have Adsense on my website. Its very confusing!

So, is there anyway to use minimal fonts? Also, I will be thankful if I can get any tutorial to enable content cache on NGINX.

Here are my test results:
