Khloé Kardashian has been busy promoting her new 30 day challenge with Protein World on social media, but not everyone is sold on her new training regime.
The Keeping Up with the Kardashians star has received mixed feedback for her collaboration with the company, who are famed for their controversial "beach body" advertising campaign in 2015.
Khloé Kardashian has received mixed feedback for her new protein campaign
When Khloé posted a video of herself preparing one of the protein shakes on Instagram, many fans were unconvinced that Khloé had been using the products, with one writing: "Nobody's buying your IG ads."
Meanwhile another user raised the point that the protein powder contains dairy – which Khloé famously cut out of her diet as part of her weight loss regime.
"So you started back using dairy? The product contains whey - the watery part of milk that remains after the formation of curds. May cause bloating," they wrote.
The reality TV star previously credited cutting out dairy to help her lose 11lbs
The Revenge Body host previously credited cutting out dairy for an 11lb weight loss in just six weeks. If Khloé is still eliminating dairy from her diet then these whey protein shakes wouldn't comply with that.
"I'm obsessed with cheese and milk, but eliminating them from my diet made the biggest difference," Khloé said in the December 2015 issue of NewBeauty magazine. "In a month and a half, I lost 11 pounds just from not eating dairy, without doing anything else different, and that totally blew my mind."
However she did motivate some of her fans, who commented that she was "an inspiration".
Khloé has lost 40lbs in the past couple of years
Khloé has lost 40lbs through overhauling her diet and exercise routine, and recently admitted that she never thought she would develop a passion for fitness.
Sharing before and after photographs of her transformation, Khloé wrote: "If you were to ask me five years ago if I ever saw myself being completely in love with fitness and health. That I would be an inspiration to many others, that I would be the push that others needed to find their way. I would've laughed in your face. Me? The chubby one? No way!"
