Hello MN-ers
So, I have PCOS and am getting fatter. Currently I'm 5'10" and around 90kg. My GP has suggested I need to get to about 65kg 
I don't eat dairy, eggs, meat or poultry, but I do eat a small amount of fish - only salmon, mackerel or haddock. I'm also allergic to peppers. I don't drink alcohol,
I'm just starting to read about 5:2 or other intermittent fasting. All the recipes for the fast days seem to include poached eggs - would really appreciate some experienced advice. Can I do this on my semi-vegan diet? Will it work with PCOS?
I did manage to lose 25kg on SW a few years back after having DS2, but I did 6 red and one EE per week, and lived off ham and boiled eggs. All my hair fell out but I went from a size 22 to a 14 and am now around a 16. I can't do it again now that I'm so plant-based.
I do have quite good willpower. Is this possible?
Thanks - and advice really appreciated :)
