How to practice Carnivore diet
For most people, this diet should be viewed as an elimination or short-term experiment, not a permanent regimen. If attempted, include a variety of animal sources, fatty fish, organ meats, eggs, to minimize nutrient gaps. Monitor lipids, kidney function, and bowel habits regularly. Supplement with electrolytes and possibly vitamin C. Reintroduce fiber-rich plants if digestion or energy falters. Long-term exclusion of plant foods lacks evidence and should be approached cautiously under medical supervision.
The evidence behind Carnivore diet
Mechanistically, very low carbohydrate intake reduces insulin and inflammation markers in the short term, which some report as improved focus or mood. However, there are no long-term RCTs evaluating brain or cardiovascular outcomes. Observational data suggest potential nutrient deficiencies (vitamin C, folate, fiber) and altered gut microbiota. Benefits may stem from elimination of processed foods or blood-sugar stabilization rather than the absence of plants. Risks include dyslipidemia, constipation, and limited dietary diversity.
