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.
