text: YouTube star Cassey Ho has hit back at critics with a powerful and provocative new video, highlighting the cruel comments left by viewers of her fitness-focused clips who accuse the trim and toned online icon of being everything from ‘too fat’ to ‘ugly’ to ‘pudgy’. Cassey's YouTube channel, Blogilates, has over two million subscribers, so fans may have been surprised to learn that the negative comments left under the California resident’s fitness videos still manage to get under her skin – and have a much greater impact on her than any of the positive messages sent to her by her fans. But though mean and critical messages may have put a dent in the 28-year-old’s self-esteem, the workout pro is getting the last word with her latest video, The 'Perfect' Body, which examines just whether conforming to society's standards is the key to happiness, while highlighting some of the cruel comments she has received from viewers of her YouTube videos. Scroll down for video. Fighting back: In her new video, Pilates instructor and YouTube star Cassey Ho combats body-shamers who comment on her videos . She's only human: Seemingly full of confidence, Cassey said even she has felt bad about herself after reading nasty comments calling her 'fat' online . In a post on her Blogilates blog, Cassey said negative comments on her videos are nothing new, but the flood of nastiness has grown especially bad lately. She added that the trash-talking has even brought her to tears on more than one occasion. 'It’s hard to be content with the shape of your body when people are constantly telling you how fat you are, how much weight you need to lose, how much weight you need to gain,' she wrote. 'What do people want?' Cassey goes on to explain that, through her new video, fans can see what it's like to face that kind of negativity, and watch as her own self-esteem gets 'stripped away', leaving her feeling insecure and ashamed about her appearance. Fit or fat: The slim and toned blogger says that the negativity in the comments section of her YouTube channel has become especially nasty lately, and has even made her cry . Peanut gallery problems: In the new video, Cassey picks at her body, honing in on places that commenters say she could improve upon . The video begins with Cassey posting a selfie in gym clothes, taken just after a workout. She immediately starts to read the comments, and though they start off positive, soon people are telling her she shouldn't give fitness advice because she is fat. Cassey goes on to strip down to her underwear, examining, pinching and prodding her body, using the spiteful comments to direct her to different parts of her physique that people insist need changing. And as the video goes on, she grows more unsatisfied with herself as negative comments pop up around her. So the YouTube star gets to work, manipulating her body in a simulation of real-life Photoshop. She thins her thighs, hips, and waist, makes her butt and chest bigger, and even changes the color of her eyes. Finally, she posts another selfie of her 'improved' look - achieved with the help of a body double - but she is clearly still unhappy, and she uses this feeling to try and show viewers that giving in to body-shaming will only leave you worse off. Before and after: The fitness expert's body goes under a major transformation; Cassey used a body double to achieve the final look . Moral message: Even after making her butt and chest bigger and her waist and legs smaller, Cassey still doesn't find happiness at the end of the video . No Photoshop here: The retouching in Cassey's video was meant to prove a point - she doesn't use Photoshop in the photos she posts online . It seems that her 'take that' attitude has left her detractors speechless. Readers of her blog flooded the comments section of the latest post with overwhelmingly positive feedback. 'Thank you for standing up to this struggle for girls and women everywhere,' wrote one fan. Another chimed in: 'I absolutely applaud that you are your natural, beautiful self. I think you’re a wonderful inspiration for young people.' Cassey hopes viewers who relate to the video's message will share it in an effort to battle body shaming and cyber bullying.
