count calories AND carbs and cut out starches and sugars
that is it in a nutshell
avoid grains/rice/potato/legumes/bread/pasta/flour/cereals/fruit/sugar
only have those if you check by your meter that they do not rise your blood glucose
you can eat the same meals as everyone but leave the starches uneaten
I have lost 42 kilo of really stubborn fat since I changed to low carb diet
on low carb diet use need small servings of fat to give you good bowel movements instead of fibre
the change from previous diet will cause some constipation but it should settle down within a few days
good luck
