She 100% crash dieted, lost the majority of the weight in around 6 months - and has stayed pretty stagnant since in terms of her fitness and physique, which is actually pretty odd considering the sheer volume of time she spends at the gym.
But when you are on a constant restrict and binge cycle (not just with food but with exercise) you will not progress.
My biggest issue with Emma, and the reason I comment here is because I genuinely think she is a very dangerous voice in the influencer space when it comes to eating and exercise for weight loss. There is a false guise of being intuitive, "body positive", fitness-focused, yet all of the content she puts out shows the opposite. She is deep, deeeeep in diet culture and her having a platform when she is this deep in it isn't healthy for viewers. She needs to be called out.
