Basically I stopped adding honey to my coffee (sad - it's delicious) and cut my fruit intake from 10-15 pieces to 2 per day. Also I eliminated all other sources of sugar such as cake, though these had been pretty minor in my case anyway.
I agree with Lustig that fruit is less toxic than concentrated sucrose or HFCS, but I am living proof that in sufficient quantities it is still bad news.
I added some extra fats (nuts, flax oil) and some extra protein (beans, peas, fish, red meat, chicken).
The best thing about the weight loss is that I lost weight in the bad places (ie my stomach) which previously had been impossible to move.
