In the quest for health and wellness, many Australians over 60 are exploring various diets and lifestyle changes to improve their quality of life. One such diet that has been gaining traction is the carnivore diet, which promotes an all-meat and animal by-products regimen. However, a recent case has surfaced that may cause you to reconsider adopting this extreme dietary approach.


A man from Tampa, Florida, following a strict carnivore diet, experienced a bizarre and alarming side effect that left medical professionals stunned. After eight months of consuming only meat, fat, and dairy products, he developed unusual 'yellow nodes' that began to ooze from his palms, elbows, and the soles of his feet. This extreme diet, which excludes all plant-based foods, has been touted by some in fringe fitness circles for its supposed benefits, including weight loss and enhanced mental clarity.


The man in question, in his mid-40s, reported positive changes such as weight loss and increased energy. However, his physical examination revealed multiple painless yellowish nodules on his skin. These were not just cosmetic issues; doctors discovered that his total cholesterol level was alarmingly high, exceeding 1000 mg/dL. To put this into perspective, in Australia, where cholesterol levels are measured in millimoles per litre (mmol/L), the man's cholesterol was around 55.5 mmol/L—well above the healthy range of 3.9 – 5.5 mmol/L recommended by Australian guidelines.


High cholesterol is a well-known risk factor for coronary heart disease, and in this man's case, it led to a diagnosis of xanthelasma. This condition is characterised by the formation of localized lipid deposits due to high cholesterol levels or other fats in the blood. While xanthelasma commonly appears around the eyes, it can also manifest in other areas, as seen in this individual.

The case study, published in JAMA Cardiology, serves as a stark reminder of the impact dietary patterns can have on lipid levels and the importance of managing hypercholesterolemia to prevent complications. It also echoes concerns raised by medical professionals about the potential risks associated with the carnivore diet.

Dr Rupy Aujla, while appearing on the popular podcast The Doctor's Kitchen, warned that strict carnivore and keto diets could be pro-inflammatory and pro-ageing. He pointed to research showing changes in key organs, such as the heart and kidneys, where the accumulation of senescent cells contributed to systemic inflammation and toxicity. These cells, which are not cleared away by the immune system, can lead to overall systemic inflammation and increase the risk of cardiovascular disease and even dementia.


While some proponents of the carnivore diet argue that it can be beneficial for those with genuine intolerances, Dr Aujla cautioned that this approach is akin to 'playing with fire', especially given the lack of long-term studies on the effects of such diets.
