hahaha..I ate a carnivore diet before it was cool... (over 10 years ago!). And I have been around in the keto and carnivore space for just as long. I have seen countless people not lose weight and gain bodyfat on an all-meat diet. I was a member of the only and first carnivore diet forum around back then. Trust me I know what I speak about... Sadly, people who are dismissing the real life experience of others and indirectly imply people are lying are just making things worse for those who were not achieving what they wanted or were promised on that particular diet (pick any...it's not lc / keto specific but here you can see the same pattern)
