I've been LCHF since June 2017. I've lost 15 pounds (would love to lose 10 more but probably won't). I feel SO MUCH BETTER! No more bloating, gas, fatigue. There a dozens of books on the subject (including KETO) that explain why/how it works, but basically, the human body does not need carbohydrates. At all! Period! I can't explain it in a blog post, so if you're interested, read Grain Brain or Why We Get Fat. Or any of the other books.
The downside is that it shows me how much I am addicted to carbs. That sugar rush (even from a potato or beets) is real and absolutely does affect how I feel. They make me fat, tired and hungry but the addiction calls them to you.
Another downside is that 15 pounds was apparently holding my face up
. I look so much more wrinkly now. But my clothes fitting better makes all the difference.
I've also had zero hypoglycemic events. And I've only had one cold (very minor one).
When our FDA finally turns its back on the sugar and grain industries, we'll all be better off.
FYI, my diet is called NSNG (No Sugar-No Grain).
