Adherence to a carnivore diet (eliminating plant foods) for at least 6 months is associated with self-reported improvements in metabolic health markers, including significant reductions in BMI and HbA1c, and high satisfaction rates, despite reported elevations in LDL-cholesterol.
If you adopt a carnivore diet (eating only animal products) for at least 6 months, you may experience significant weight loss and improved blood sugar control, with high satisfaction. However, be aware that your LDL cholesterol may rise significantly, although other heart health markers like triglycerides often improve. This data comes from a self-reported survey, so individual results may vary, and long-term safety is not fully established.
Participants reported high levels of satisfaction and improvements in overall health (95%), well-being (66%–91%), various medical conditions (48%–98%), and median [IQR] BMI (in kg/m2) (from 27.2 [23.5–31.9] to 24.3 [22.1–27.0]). ... Among a subset reporting current lipids, LDL-cholesterol was markedly elevated (172 mg/dL), whereas HDL-cholesterol (68 mg/dL) and triglycerides (68 mg/dL) were optimal.
Why this rating
The study is a cross-sectional survey with significant selection bias (survivorship bias), self-reported data, and no control group, limiting causal inference.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
