I'm a diabetic, so I have to mind my carb intake, but I will not try to cut out carbs altogether. People on extremely low carb diets suffer from nutritional deficiencies, and when they cut out carbs that have vital nutrients, they become malnourished.
I think the problem is with junk carbs -- the potato chips, cookies, etc. They have little to no nutritional value and are also loaded with fat, particularly saturated fa, and of course, excess sugar and saltt. I can see getting rid of those. But potatoes, for example, are loaded with B vitamins, among other nutrients. Those vitamins are necessary for good health and you don't want to cut them out along with the carbs.
