This will likely only happen this once, but I feel really really bad for Yawn, terrible in fact.
It appears she has struggled with her weight since at least she started in FL, likely before that as well. She has been yo-yo dieting and using the FL supplements and C9's ever since.
She appears in a widely shared photo where she lost over 2 stone many years ago.
I saw a video where she added about 600 calories worth of peanut and coconut butter to a weight loss smoothie.
She doesn't appear to know how to count calories and eat healthily and that this has to be done forever. Weight doesn't return when you go back to a 'normal' diet. Your interpretation of a 'normal' diet was what caused the excess weight to begin with. Hence why you have to learn how to eat so that you ingest roughly the same amount of calories you burn each day.
C9 just encourages you to crash diet and yo-yo diet, it's not healthy.
With all the money she has spent on the C9's, which is likely thousands of pounds, she could have sought out a nutritionist. Or for no money she could just have stuck two fingers up at the world and not started crash dieting in the first place.
If you want to lose weight then lose weight, but do not body shame others into doing the same. I've seen her sell the C9 to women who obviously have a BMI under 25.
She obviously has poor self esteem bodywise, which is stupid. I don't like her, but there isn't anything wrong with her body the way it is. She should learn to love the way she looks instead of trying to change it with magic beans.
