BEWARE..... MINI SOAPBOX ALERT BELOW.
My coach allowed for NO extras for the first 70% of weight that needed to be lost. I was without extras for almost 6 months. It worked for me and I lost about 80 pounds.
I honestly think the longer you can go the better off you are.
That isn't so much an issues these days and I have been told directly by people with IP that I did it not only the hard way but, a way they do not approve of now.
There is a reason that restricted items are now allowed from week one and it is because some people need them.
If you are not using restricted food items but are adding a carb from sugar free ketchup, dijon mustard, flax seed, black soy beans, shirataki noodles or some other element and you are keeping yourself in ketosis (under 30g of carbs a day) you are fine.
Just THINK about it, many people on here are losing using alternate products to do the IP PROTOCOL... THAT IS NOT IP... Sorry folks, it isn't. It uses the principals but, you will never get an exact chemistry and formulation with all the unknown elements of those foods. We know some things are closer in formulation than other but, you get more or less protein, an extra carb, extra fat, extra fiber, extra vitamins, or LESS of all those things when you choose EAS, ATKINS, PREMIER, MATOL, NASHUA, LINDORA, NEW LIFESTYLES, Syntrax, or any other substitute. Even when they come out of the same factory they are not formulated EXACTLY alike.
SO, to make those little adjustments on your own, using product you find convenient... is as fine in my book as saying you are doing IP when what you are doing is an IP PROTOCOL. Which works in all cases if you stay in ketosis, in an unbalanced diet phase, with low calories/low carb/ and low fat.
The diet is designed to rest the pancreas and make it more manageable for you to "stick with it" by being planned the way it is. It does not have to be ridiculously crazy and if you ever compare Dr Tran's original diet in his book/website to IP you will see he is even more liberal and his people still lose.
If what you are doing is working, you are losing, you aren't having cravings, and you feel like you aren't fatigued then you are doing what is good for you. Let that be your guide. More or less, we are all unique and our bodies are our little labs.
I have tasted and sampled many of the alternate products. They work fine for me and for maintenance I will incorporate them in and, for anyone who wants to do this on a smaller budget they are a great alternate option. I will not slam anyone for doing an alternate plan and I won't ask but, I won't fuss over 5 or 7 odd carbs coming from other reasonable sources either.
Sorry, off my soapbox. That is my little opinion.
ALSO, I don't know exactly where it got going, and I do know I have shared it, but, when I got my literature and started this diet NO WHERE did it say stay under 30g of carbs a day. I was told eat on the program and you are fine. I learned that little carb value thing HERE. And, yes, some coaches go by it. The truth is, some people are in ketosis at 60g of carbs a day and some at 20g a day. The lower you are to start the better the "induction" to borrow an Atkins phrase. It is not necessary to stay at that level indefinitely if your body is able to be in ketosis at a higher level. So, even that concept we readily attach ourselves to is very narrow and limiting and, in some person's case incorrect. Trust your body to let you know if you are in ketosis, it is apparent, you will lose well and lose inches too. Trust the diet and FOLLOW it.. The guess work is taken out of it if you do.
