How successful were you in loosing weight question?

After my PSC diagnosis, last year, my hepatologist strongly suggested the Mediterranean diet. Fruits, veggies, nuts, beans, etc... more fish & poultry (little to no red meat). Kick the processed foods (Chips Ahoy, Cheetos, Pepsi) to the curb. I wasn't a big guy 155lbs before diagnosis, now just over 1 year later I'm weighing in around 140lbs. I know 15lbs doesn't sound like much, but think about it in percentages (I now weigh ~90% of what I used to weigh).
