I make it very easy;
I eat fish or meat or birds as I always have done(about 200 gram). I eat as much vegetables as I can( ususally 3-400 gram), avoid rice, potatoe and pasta and makes sauce from full fat cream or sour.
In meat, fish, chicken there is none carbo.
Depending of which type vegetables you choose there will be carbo. The same in dairyproducts; you have to read and measure to know excactly how many carbo there is.
In the beginning I always measured and counted and tested my BG. Now I know how much carbo there is in for example broccoli and how much of broccoli will give for excample 5 carbo.
A typical dinner for me would be some type of meat- 3-4 oz ( steak, bunless cheese burger, chicken or pork), large salad with 0 carb dressing and some type of veggie like mushrooms, spinach, zucchini, etc. Usually for dessert I will have a Breyer's Carb Smart Bar.
