I’m not sure I should but I’m gonna answer.
I read through the article you posted, Bill C. The reasons they were stating that we needed a high fiber diet are: 1) for normal bowel movements, 2) bowel health, 3) lowering cholesterol, 4) helping control blood sugar, and 5) aiding in achieving a healthy weight.
Some people do have a harder time adjusting to a keto diet than others. That’s well known. But bowel movements normalize over time. If they don’t, it’s time to seek help, and people do. (Sometimes it can be adding fiber, sometimes it is avoiding fiber.) As I have stated, I do not have a problem in that area. My bowel health is just fine. I have no issues with diverticulitis. I do not have hemorrhoids. I eat things like yogurt and sauerkraut and have a healthy gut bacteria.
I think there is quite a bit of data out there that proves that people can and do have healthy cholesterol levels with a keto diet. You can bark up that tree for a very long time and you’re not gonna get much satisfaction with real people eating a keto diet. Besides, even mainstream medicine is finally starting to (reluctantly) admit that maybe cholesterol isn’t the monster it’s been made out to be the last few decades.
If you spend any time at all here, you know there are hundreds if not thousands of people here who have either dramatically lowered their needs for diabetes meds or gotten off of them completely by eating a low-carb / keto diet. This is not new, it’s been around for decades. This is not quackery. People are normalizing their blood sugar with a ketogenic diet. And there are real medical doctors seeing real patients that advocate a ketogenic diet to their patients and have excellent results year after year. They don’t need Stanford or Harvard or any other university or medical school to tell them how poor of a job they may be doing with their patients. They have the feedback right there in their own offices.
Finally, as for the matter of maintaining a healthy weight, maybe you should look at the company you’re in here. There are very few people who are not improving their situation on the keto diet, losing weight, getting closer to a healthy weight or maintaining a healthy weight while eating a low-carb / keto diet. I’ve lost 70 pounds and am getting close to my weight goal. Others have lost more than that. It’s pretty common with people who’ve adopted a keto way of life.
So I’ll ask you the questions again, how do you quantify how much fiber your body needs and how would you know if you’re not getting enough? If it’s a matter of being satisfied that the five things mentioned in the above article are satisfactory in the person eating a ketogenic diet, or at least going in the right direction, It would seem the person in question is getting enough fiber.
That said, there are some people who do not do as well on a keto diet. Some of it is genetic. Some have tried it and not done well and then moved on to some other way of eating that works for them. If you are one for whom keto doesn’t work, why stick around here? Go find a good fit for you. Hey, I tried for decades to be a plant based vegan and vegetarian. (Talk about high fiber!) I ended up prediabetic, obese, and set up nicely for a heart attack and/or stroke. That’s not the kind of health I was looking for. Keto has turned a lot of that stuff around for me. I’m in better health then I’ve been in 20 years and still improving. So when I read a news story from Harvard or where ever that tells me I need to be a plant based vegan or vegetarian to be healthy, I’m sorry, I just can’t do that. Been there, done that, it wasn’t good for me. I wanted it to work for me, I really did. I wanted to prove how healthy it was. And I still kinda envy people who can eat that way and be healthy. I can’t.
Hitch your wagon to whatever star you choose. But if you should find yourself going the wrong way, unhitch and find a new star. Good luck in your journey. I hope you find what you’re looking for.
