Miranda, from Wisconsin, US, has gone viral for her hilarious relationship advice, disguised as fitness inspiration.
On Sunday night, she tweeted: "After getting called disgusting last night, I successfully dropped 200lbs!! (90kg)."
Her tweet included what she described as "before and after" pictures and showed her and her boyfriend in one picture.
The "after" shot was the same photo, but with her boyfriend cropped out of it.
