I did the whole 5 days high fat/high protein and carb up on the weeks but I no longer do that. I've gone two weeks without carbing up and I felt fine. I do however carb up one day every 4-5 days.
Quote from page 95 Chapter 4 of "The Metabolic Diet"
"
Don't Mix Diets"
"The big temptation may be to mix diets combining aspects of both the high-carb and higer-fat diets and putting them together in your own personal Frankenstein stew.
Don't. Many people will go on the higher-fat/lower-carb diet but try to be true to their old high-carb master. They'll eat meat but it's all skinless fish, chicken and turkey.
While these foods may be quite nutritious and beneficial, even when used in the higher-fat/low-carb diet, they can't replace good, old-fashioned red meat. There just isn't enough fat there, although it's somewhat better if the skins are included.
What you end up doing by taking on the turkey/chicken/fish holy trinity is going on a high-protein, low-carb, and low- to medium-fat diet. Along with being even harder to stay on the Metabolic Diet weekday menu, this diet will severely limit your progress. You won't burn the fat like you should and you won't have the energy.
You need red meat. You need the fat and the nutrients it provides. Don't shortchange yourself by trying to avoid it some misled effort to stay true to forces in society who have labeled meat some kind of monster."
Jorsn, you should be following the diet
exactly as described. You can't pick and change things, you have got to stay on the low carb portion for 5 days, no less, no more. There should be no "tweaking" involved unless you mean reading more about the diet in the book and getting the details more precisely planned. If you don't have the Metabolic Diet book, get it already. There is no "winging it" when dieting. You will get out of what you put into it but if you don't want to take the time to read the book or spend the money on it than I don't know what to say. Sure you may be losing "weight" but there is a reason for the carb up days and a reason they are timed the way they are.
