A total of 2029 respondents (median age 44 years, 67% male), reported consuming a carnivore diet for 14 (interquartile range 9–20) months, motivated primarily by health reasons (93%). Red meat consumption was reported ≥ daily by 85%. Under 10% reported consuming vegetables, fruits or grains > monthly, and 37% denied vitamin supplement use. Prevalence of adverse symptoms was low (<1% to 5.5%). Symptoms included gastrointestinal (3.1–5.5%), muscular (4.0%), and dermatologic (1.1–1.9%). Participants reported high levels of satisfaction and improvements in overall health (95%), wellbeing (69–91%), various medical conditions (48–93%) and BMI (from 27.2 [23.5–31.9] to 24.3 [22.1–27.0] kg/m2). Among a subset reporting current lipids, LDL-cholesterol was markedly elevated (172 mg/dL), whereas HDL-cholesterol (68 gm/dL) and triglycerides (68 mg/dL) were optimal. Participants with diabetes reported benefits including reductions in BMI (4.3 kg/m2, 1.4–7.2), HbA1C (0.4%, 0–1.7), and diabetes medication use (84–100%).

Conclusions

Contrary to common expectations, adults consuming a carnivore diet experienced few adverse effects and instead reported health benefits and high satisfaction. Cardiovascular risk factors were variably affected. The generalizability of these findings and the long-term effects of this dietary pattern require further study.

I still eat fish, but I have given up beef, chicken and pork for ethical and environmental reasons. I lost 13 lbs and feel great.

What does all this mean?

The old model of atherosclerosis and heart disease suggested that arteries were like pipes, and cholesterol clogged them.

In reality, atherosclerosis is an inflammatory disease.

Triglycerides and HDL are markers of insulin resistance, which raises inflammation.

Is there a simple way to identify insulin-resistant individuals at high risk for cardiovascular disease? Yes, a triglyceride/HDL ratio of >3.5 identifies them.

The ratio of triglycerides to HDL is the most important blood lipid marker.

With that said, you do you, brothers. If eating meat all day works for you then don’t stop.

But I haven’t lost anything other than body fat on my relatively low protein plant based diet.
