This isn't specifically commenting about your, but I love how wildly different these comments are. The one currently below you said they improved when they switched to a plant-based diet.
Everyone is different, but I just thought it was funny to see how different everyone is.
I'd imagine both diets cut out bad things while prioritizing either mostly meat or mostly plants. E.g you go from a poor, unplanned diet to an improved, focused diet and it will work well.
I am eating lots of plants along with meat, but I would say my 75% calories now come from meat. I dont have stomach acidity (i used to have it since grade 4), frequent migraines, IBS. I have increased mental clarity, better focus, better sleep.
I would attribute most of these changes to grains/gluten reduction than meat adoption.
