The author conducted a week-long experiment with a carnivore diet, consuming only beef, butter, salt, water, and espresso, with occasional lime juice, in an attempt to assess its health effects. With no prior research, they were motivated by a recommendation from someone who claimed the diet made them feel healthy. The author's observations included not feeling overly hungry despite reduced calorie intake, but experiencing headaches by Thursday, which they attributed to a lack of electrolytes and mitigated by adding lime juice to their water on Thursday and Friday mornings.
