Absolutely not, carnivore diet doesn't cause metabolic slowdown. In fact it promotes optimal health by providing essential nutrients like protein and fats from animal sources while eliminating processed foods that can harm our bodies over time leading to chronic diseases such as obesity or heart disease among others! Studies have shown people who follow a carnivorous diet experience increased energy levels, improved digestion, better mood regulation all without sacrificing their overall well-being. Don't believe me? Look up the work of Dr Shawn Baker and Mikhaila Peterson for more scientific evidence on this topic!
