Good on you for trying again.
i did the same thing. Four years ago when i got diagnosed with diabetes 2, I lost 13 kgs through a similar diet(I was not aware of BSD at that time). My sugar levels were great and felt so much better. However, changed jobs, highly stressful and with in 6 months all weight was back on and sugar levels were again scary.
About 6 months ago I started exploring the idea that i had food addiction. If there was food in front of me i had to eat it. Next three months were a real struggle- I was trying to curb my eating without much success which led to anger towards myself.
I cant say what changed two months ago. I went and bought book , read it and then read it again ,suddenly, a switch turned on and here i am 10 kgs lighter- sugar levels are erratic but they will settle down.
I can still succumb to curries ,especially when my son gets takeaway but have had a naan or roti in two months.
i am extremely satisfied as of now.
I just want to wish you all the best for your venture with BSD.
