I’m not sure what I’m meant to take from those links. Do you know of any direct studies comparing similar macros etc to isolate meat or any longer term analysis across similar target demographics? The first one seems to be about low carb vs high carb - where was the meat + carb vs no meat + high-carb comparison? The second seems to be specific to milk and not animal products in general.
