As someone who lost 40kg by just eating mostly meat (one year meat for lunch, salami for dinner), I’d argue it’s healthier than the stuff that’s advertised to be healthy.
wanna build muscle? well, eating pasta and salad every day won’t get you very far.
Sure, there are other protein sources, but let’s be honest, nothing is more nutritional, efficient (and delicious) than meat.
I think we should really focus on the truely unhealthy shit that’s out there in the supermarkets, and not on meat.
