One of the biggest problems when starting low carb is the hunger pangs and the need to eat your favourite foods.
Depending on where you are on the road to better control, you really don't have to do without some of them. Just the really bad ones!
It's about portion size.
The reason a lot of T2s don't eat these foods is because they know what the effects would be if they indulge.
I think that if you can discover your baddies and concentrate the goodies that don't spike you too .such you will be getting somewhere.
There are always alternatives.
Because I have to very low carb and experimented with different foods and found that my tastes have diversified and eating stuff that I never thought I would, salad is great if you get the combinations right.
Tastes change and if you know that it is beneficial, it makes you feel much better.
Plan your shop, plan your foods that your gonna buy, do it on line so your not persuaded to buy something you can't resist, if it's not in the house, that is half the battle. You like fish, have it without the batter, bake but don't eat too many, curries are low carb, soups are low carb, find different ways to cook meat. Steak with onions mushrooms, bacon, gammon and eggs, I'm getting hungry now!
Plan ahead, if I can, you can.
Best wishes.
