It's all on the blog:
Specifically, weight loss is mentioned under "Meet Esther " (pull down the "about" tab). She makes reference to body image / weight in a couple of places eg
- "I was born with eczema and spent weeks in hospital and it meant during my school years I was bullied. For years and years I've had an issue with my body image yet now I've turned that around for good!" and
- "I was in desperate need to slow down and learn what it meant to look after myself. Cheesecake, pizza and late nights juggling 3 jobs were not the way to health and happiness. Ending up 30kg overweight, friends not recognising me, high blood pressure and finally a virus which later lead to a ME/CFS breakdown, frazzling my nervous system should have been enough of a warning sign but no I still pushed on and on. ...."
There is a
absolute mass of very personal information about Esther and Dan, and their relationship on the blog, including information about disagreements they had (see
17 Years On - A Relationship That's Totally Perfect In Its Imperfection | Esther & Dan - Adventuring Together - Life, Love, Health & Travel). It's incredibly personal. The "about our blog" pages states "we decided that we wouldn't try and remove or change any of the older posts on the blog. It's a record of our journey." - hopefully each of them would be able to disable the blog if they changed their mind on this.
IMO Esther was struggling (dark clothing - no evidence of the bright clothing referred to on the blog), and struggling to take proper care of herself (possible inadequate food supplies). For all the apparent freedom the lifestyle had no stability or real direction (nothing wrong with this - a lot of people go through the same), and so much time alone to overthink things - perhaps leading her to make decisions that were different from those expected of her.
