You'd have to stick with vegetables and fruits, but even then there's debate over what is truly healthy. Is corn healthy? Is wheat healthy? Are carrots healthy?

You'd have to stick with vegetables and fruits, but even then there's debate over what is truly healthy. Is corn healthy? Is wheat healthy? Are carrots healthy? They're all plants after all, however... All three are high in carbohydrates and would be considered "unhealthy" from a keto-perspective. The best bet here: don't listen to one source of information. There are literally thousands of experts on diet, health, and nutrition, no one of them is totally correct. Find what you can tolerate, what you can stick to; eat mostly plants, and not too much.
