This has lots of potatoes that are high in carbs, so I don’t think it’s keto. Also, everything is healthy in moderation (except stuff like smoking, alcohol) and unhealthy if you eat to much and the keto diet is definitely not for everyone, so be careful making those generalized claims.
Again, I’m happy that worked for you but it is not true for everyone and no claim like “sugar bad, fat good” is ever going to help everyone get more healthy. I myself lost weight by increasing fiber and protein (so many lentils and beans) and decreasing unhealthy snacks. But take my pasta and bread and I will feel unhappy and unmotivated and not move a muscle all day.
