My most recent keto "find" doesn't involve food at all, but rather the lack of it.
For the last few weeks, I've been experimenting with a technique known as intermittent fasting (or IF) which is described in several keto resources, where you rely entirely on fat stores to provide fuel, rather than dietary fat.
Today I'm on the second day of a fast that began Tuesday evening. Weirdly, I don't feel much hunger at all. In fact I feel great, and was even able to go for a workout yesterday afternoon. I guess this is one of the advantages of being fully adapted to burning ketones instead of glucose derived from carbohydrates. Six months ago I wouldn't have been able to go without food for more than 12 hours at most.
The only "food" I've consumed has been coffee with cream in the morning, and just water for the remainder of the day. Tonight I plan on having a real dinner.
This has also (not surprisingly) brought my blood sugar down considerably. Yesterday it was in the low to mid 70s most of the day. When I got up this morning it was 79. Normally my BG is always around 90 in the morning. I'll continue to check it throughout the day to make sure it doesn't drop too low.
