She claims her breasts have grown since starting a carnivore diet, which is believable if she was too skinny and malnourished before.
This other girl grew a round butt after starting a carnivore diet:
The asian chick in the video used to be vegan so it's 100% certain she was malnourished .
In her videos she talks about needing to eat a lot of fat and she is essentially on a classic ketogenic diet (70% + calories from fat and zero carbs)
I like steak but I don't want to eat 2 pounds of it every day. I can't even tolerate eating more than about 6-8 ounces at one meal.
I don't know of any bodybuilders (natural or enhanced) who use this diet. I don't believe the BS about Nubret. He might have gorged at night but I'm not buying the 5lbs of horsemeat at one meal and he was also known to eat rice and beans and he supposedly like french pastries too.
I don't know many bodybuilders (especially natural ones) who follow the carnivore style diet.
There probably is someone (that Trystin Lee kid comes too mind and Mark Bell)
BTW - this is another video she made with her boyfriend (who wants to gain muscle) and he couldn't follow the diet.
This video is kind of hilarious for because of the concerned look in her eyes as he's explaining why he couldn't stay on the diet. He may no longer be carnivore but at least he still gets to enjoy the benefit of the carnivore diet via his girlfriend new big boobs.
Bottom line is that if it works for you that's great but it's definitely not ideal for everyone (for a variety of reasons)
