For a temporary diet or a specific health benefit this is a good option but long term can definitely can issues.
I have found the same to be true with the Carnivore diet as well. But everyone is different.
We try and eat more of a "European Diet" aka "fresh foods diet".
For breakfast we typically eat free range eggs and a piece of sourdough bread toast (sometimes also homemade 100% spelt pancakes or yogurt).
For lunch we each usually eat a sourdough bread sandwich with nitrate free ham (or leftovers) and german style saurkraut.
For dinner we usually eat some sort of veggie and meat (a homemade stir fry, soup, stew or other). Sometimes also a salad and a meat with another veggie because the little boys have picked up on salad yet (except our youngest who LOVES it!).
For snacks the boys and I usually have fruit and sometimes cheese with it.
Everyone has almost unlimited access to raw milk and kombucha for drinking throughout the day at any time.
Obviously we visit family and there are days when we have exceptions when we are sick but I found I have less pregnancy sickness and tend to have a more healthy weight and general health with a balanced whole foods diet. (American portion vs. European portion size is also a big things to consider.)

When I have more energy I sometimes make homemade spelt bread, pizza, muffins, etc. for lunch. And this afternoon for a snack we had run out of fresh fruit and I was under the weather so we had tea and homemade smoothies instead (frozen fruit with a raw milk, a little sugar and a dash of salt.
