Do what makes you feel energetic and happy. I was eating purely veggies in the morning (cooked in bacon fat) for a while and I must admit, I felt light and reasonably upbeat. I'm trying to slowly strip away cards and most veggies now, I'd like to try carnivore for a while and see how I feel. I think the plant based diet stuff works the same way keto/carnivore does, it can happen but most can't properly balance it. I think the negative attention called to either is mostly based on a lack of full commitment, keto for instance requires way more fat that most realize and seems to require supplementing salts like magnesium, plant based requires protein etc.; if you skip out on that stuff you are gonna have a bad time.
