Hi I am new here. I started the Dr Atkins diet in 1976. I lost loads of weight! Now many years later I am grossly obese and have numerous health problems. I keep trying to use Dr Atkins but get very dizzy, sweaty and panicky. I believe part of the problem is because I am now hypoglycemic. Which means I need a certain number of carbs to maintain the balance. I am now starting the diet with 25 grams of carbs and will see if this helps the lightheadedness. I think this is an option to investigate for those who are having the same problem. I also have found if I am not eating enough calories this too causes lightheadedness and dizzy spells.
