I think that a big, big reason that people are scared of trying something like the SCD is the total absence of sugar.
On SCD you can use fruits and honey, sparingly. That's about it.
Here's some fun blog posts that I found on the topic:
Modern Forager confirms that the best sugar for us is honey, sparingly. I agree!
Pay Now, Live Later tells us that we're all sugar junkies -- well, those of us not on SCD, at any rate.
Sugar is a drug. Don't believe me? How about all those people in this country eating themselves to death, with skyrocketing rates of obesity?
That's not lack of willpower, kids. That's ADDICTION.
I was completely and wholeheartedly addicted to sugar before SCD. I did not know what it was like to not be hungry, because I was always hungry. My blood sugar was out of control along with my appetite.
During my first week on SCD, I thought I would die. It was a true and serious withdrawal.
And then I felt great afterwards, and forever more.
I can walk right by those giant muffins, because to me they are no longer food. People look at me with pity. But then I see them returning to the muffins again and again...telling me they just can't stop thinking about them, that "it was calling to me."
Yeah, that's one voice in my head I do not miss at all.
