Ohaiyo-gozaimasu Back to you but I bet it is night there now!!!
most allow fat but there are some that balance things out much more as exactly how much fat and how many carbs and how much protein you can eat in each meal including snacks. I think that would be too hard to figure out as i need to just shove food in the face and run!!! although many do it and do wonderful. the Carb addicts diet can be low fat and low carb for those that really need the feeling like low fat. BUT NOT ME!!!! do not kill me with too many restrictions.
Start first now with slowly cutting out the diet coke. You will have a carb withdrawll headache you do not need a caffiene withdrawll too!!!
