I can't even finish reading this article. Low-fiber on the keto diet? What about avocados, nuts and seeds, salad greens, cucumber and zucchini, crucifers, asparagus? I could go on.
I'm not aware of a study which looks at the long-term effects of ketosis in humans. Rather, what I find is studies looking at the long-term effects of eating cheese and hot dogs at every meal, and some inapplicable rodent studies.
If only paleolithic people had access to kale they might not have gone extinct.
Look how bad a vegan diet is:
As someone who has successfully done keto multiple times, to read that the diet risks being low on fiber shows that they really don't understand the diet at all.
Dietary Fiber is basically the "get out of jail free" card for keto. It was incredibly common to see something tasty in the grocery store that I might be able to eat, then pick it up and feel disappointed when it had like 12g of carbs. But then get excited to see that 10g of that was dietary fiber, meaning it's only 2g net carbs!
It's also weird that this "nutrition scientist" claims keto is at risk of micronutrient deficiency because... Grains don't really have a ton of micronutrients. Wheat, rice, soy, That's why we fortify cereals. Without that fortification, grains provide some B vitamins and some heavy metals like iron and magnesium, but the vegetables you mentioned like avocados (and I'll add spinach and broccoli to your list too) are better sources of most of that anyways.
Yah I thought that was pretty egregious. Even if they're not getting Vit D from their food, they can easily supplement - half the population up here in the Frozen North already does that. I will continue to give paleo people shit about their diet being completely ahistorical, but as healthiness goes it seems fine. Wierd and baseless, but fine.
