I just found out that the kefir I ordered isn't real kefir. I have no idea what it is. So I ordered some real kefir grains and some mason jars. Ungh, what a waste of money.
In other news, my diet has relaxed a bit. The very low carb lifestyle is very good for those who have damaged their insulin producers/receptors/whatever. Having been very thin for most of my life, and catching the weight from high-carb veg rather early, I think I'm 'safe'. So, while I was never really low carb, I'm accepting moderate carb as my diet - 25-30% carb, 20-25% protein, 50% fat. This is still half the carbs of the average SAD, but it is much easier for me on a vegetarian diet, especially considering the fact that my family eats out every week, etc.
It's also good because I've decided to start training for ultra marathons, so my glycogen stores need to be reasonable.
Ultimately, I'm going to eat what's on hand that I want to eat. This experiment into as-low-as-possible carb has taught me that fat is GOOD! Add fat to everything! Nuts are the yummy fat candy of nature! It has also taught me that eating carbs with proportions of protein and fat (the same weight of each is a good estimate) seems to be ideal, and that all opportunities to not eat sugar or grains should be taken. Potatoes = okay; poptarts = bad.
That said, I'm still eating a ton of sushi and rice in Japan!
