yes.... BUT. I can lose weight very quickly when I do not eat carbs. And I will do 2 carb free days in a row about every other week. The big BUT is that you do a total low carb diet for months and months - when you return to normal eating, and you will eventually have to return to normal eating - you can gain the weight back supper easy. When you do eat carbs they need to be of the fruit and veggie variety, and you will probably never be able to eat white foods (white bread, white rice, white potatoes, etc.) on a regular basis again. Roll with dinner once or twice a month - ok. Daily turkey on white bread. No good - you will gain all the weight you lost by doing low carb right back
This is just my personal observations and experiences - YMMV.
