The comedian is competing in the BBC One show with pro Karen Hauer and at the weekend she embraced body confidence by donning a black leotard for a Flashdance-inspired routine.
The performance went down a storm with most viewers, but some trolls attempted to fat-shame the star over her shape.
Adams has now hit back with a message on Instagram that said: "Them: She shouldn't be on Strictly because she's fat.
"Me: If I stay on Strictly, I'll get less fat."
In the caption, the star thanked the fans who had been supportive and assured them she would not let her mental health be affected by the abusive remarks.
"I’m getting lots of nice people sending me many DMs worrying about my mental health because stupid people are saying silly things about my weight after my thighs went viral on Saturday night," she said.
"You need to know, I would never allow someone who doesn’t see the idiocy of this logic, to affect my mental health AND if it did creep in, not only do I have Karen but I’m surrounded by people who would either gather round me or if it got REALLY bad, they’d track them and pay them a visit I’m sure."
She went on: "If there was something that wrong with me, I wouldn’t be able to dance six hours every day and lift Karen.
"Because of how stupid this logic is, I suspect their issues aren’t to do with me at all. But women always get it in the neck don’t they.
"I’m not ignoring it, I’m addressing it. The more I show resilience to it, the more other people will be able to and that’s useful I think."
"I love the love though," she added, before signing off: "All MY love, from me and my massive thighs."
Fans called Adams an "icon" and an "inspiration" after her post.
And TV star Dawn French posted: "Go mighty thighs!"
