I adopted a low-carb diet, after much searching for relief from long-term illness. But mine more involves a liberal saturated fat intake (from meats, dairy[butter, cheese, and at one point coconut oil but that proved to be a bit expensive]), and not so much fat of the plant variety (except that of coconut). Think paleo diet.
I will never go back to the way I used to eat. Every now and again I allow myself something that I shouldn't, but I pay for it.
There are certain foods I decided I could have again, after I had cut them out of my intake for a while (potatoes, fruit), as a result of substantial improvement in health,
But then my sensitivities kicked up again, and I knew why - too much intake of carbs.
There are more and more (formerly rare) sensitivities becoming more commonplace every day - such as that of gluten. -Why? - Well, wheat as it exists today has evolved. It's no longer quite as it once was. In it's grass form though, it's fine. It's the grain part (particularly the gluten) that's causing problems
It was rather hard at first, because I didn't know what to eat. My diet had consisted mostly of breads and fruits and soy and potatoes - bearing in mind though that fruit is healthy, and potatoes may be - the jury is out on that one -- but moderation is key.
I think of it this way: fruit is not naturally available year-round. So it isn't natural for our bodies to consume a lot of it.
I get some flack from people who have no clue that there is a Huge difference between a low-carb diet and a No-carb diet.
My diet is not carb-free. Carbs are a necessity. But there are different types and some foods are absolutely loaded(think bread type items and commercial snack items in general), and people just don't realize it, or what it's doing to there bodies, and consume tons (as I did for years).
It's still hard - but SO worth it.
There are similar diets, such as GAPS, FODMAP, and, one used to treat autism in children, SCD (specific carbohydrate diet).
Hope this helps someone.
