She’s an absolute joke, there is no difference between those photos & anyone telling her otherwise is lying to her. She seriously needs to give this diet up as it is extremely unhealthy & if what she is posting is true she is starving herself.
Her family/friend/fiancé need to have a word with her & tell her she needs to stop. Meal replacement shakes are not good to begin with but her documenting her half arsed effort to 19k followers she is just making a fool of herself.
The issue is she is going from one extreme to another, she thinks by starving herself she is going to get instant results but she ends up just binging which, after a period of starvation, will cause her body to grab onto all the calories and fat it can get and will store it to prepare itself for the next starvation phase.
this is exactly why she isn’t losing anything. It’s completely idiotic and pointless.
If she just went on a simple 500cal deficit which for her size I would guess she would need to be on about 2000 cals a day, she could eat normally every single day and will still lose weight every week.
