Whatever her method for weight loss, it isn't healthy, and she knows it because saying she goes to barrys bootcamp just ain't cutting it.
Weight loss - diet 80% exercise 20%
You just wouldn't see weight loss of that extreme from exercising now and again especially since she isn't toned she's just looking more and more emaciated.
It would be a breath of fresh if she just put her hands up and said, "You know what, thanks for all the comments of concern [sorry for deleting them], I'm fine, it's just I've lost my appetite a bit and stress has contributed too." All of which is down to divorce I imagine, which she should also admit, it would be a comfort to many.
But no, these influencers, have to portray the perfect life, the perfect body and make it all sound effortless leaving us normal people feeling inferior and buying what ever products they flog to try and be the same. It's so fucked up.
She could really reboot her career and become relatable by talking about the struggles of divorce etc but no, no, doesn't fit her perfect life, still besties with ex etc etc
