The decision to get off the grain ride is the biggie. It will most likely take you a while to get your mind around the idea. Anybody can do it, but it takes some mental prep.
Tell yourself that this is a way of eating that will not leave you hungry.
There are different ways to do this. Some people go cold turkey and never stray from the rules. We know of others who stick to the rules for six days, and give themselves a grain treat on the seventh day. Decide which method will work best for your personality type.
Then, set yourself some goals. Start by challenging yourself to stick it out for two weeks.
You might want to document your results and the way you feel in a journal.
You need to be aware that the first five days or so will likely be the hardest, but from then onwards your body will get used to it. You won't be hungry, but you will find yourself craving something from the forbidden list. The way to overcome this is to get yourself a snack from the list of foods that are allowed. Don't worry about calories too much in the first week. Grab a handful of nuts if that helps. Drink a cup of tea. Go for a walk. After about 20 minutes, you'll feel better. Tell yourself that this will pass. It will.
After two weeks, you'll notice it's easier than you thought possible. You'll also be feeling really good. After six weeks or so, you'll notice that any arthritis aches and pains will be diminished. What a bonus!
