Having lost weight on the Fast 800 as a vegetarian, then plateaued for a bit, then eaten rubbish for the last month, I want to try another few weeks, six maybe, on a low carb preferably vegan diet. Has anyone done this, and has it impacted their health negatively or positively? I would be eating more than 800 cals a day, ideally, but enough for weight loss. And taking a vitamin/mineral supplement too. Any suggestions for meals would be helpful too. Want to lose about a stone and improve general health. So far today had a green smoothie (kale, pear, cucumber, celery) which are although disgusting, weirdly energising.
