The number one instagram page I would recommend is @saggysara on Instagram 

https://www.instagram.com/saggysara/

Her message is beautiful. She posts pictures of herself when she's posing/not posing, using a filter/not using a filter, she posts about trends and how the natural human body looks like. Under her pictures she writes lengthy captions about her experience and why we should not think the way we think nowadays. I have the utmost respect for her and how brave she is and her whole message. I have been following her for a while now and it always makes me smile. Here are just a few examples:

The other two resources are websites.

Adios, Barbie is about body image issues among people of all genders, races, body types, ages, sexual orientations, etc. They encourage people to think critically about their media consumption and shift from being consumers to active participants in the media culture (media literacy tab at the top). There are blog posts, articles, and information that helps everyone feel comfortable in their own skin.

I will let them speak for themselves from their "about" section: "Lindsay and Lexie help girls and women recognize and reject the harmful effects of objectification in their lives through their significant social media reach, online Body Image Resilience course and facilitator program for dieticians and therapists, their popular book (More Than a Body), and regular speaking engagements for thousands of people of all ages."
