A 2025 paper in JACC: Advances claiming the ketogenic diet does not promote arterial plaque formation has been retracted after widespread critique of methods, data access, and potential conflicts of interest; the journal said the errors were too significant to fix with a corrigendum, and independent reanalyses raised further concerns, fueling ongoing debate about nutrition science and disclosure practices.
A TODAY dietitian warns against ultra-restrictive weight-loss diets that ban foods without clear medical reasons, saying they are hard to sustain and undermine eating enjoyment. Instead, focus on small, gradual changes that emphasize protein, fiber, smarter swaps, and portion control to create a sustainable calorie deficit.
Kennedy’s claim that ketogenic diets cure schizophrenia is not supported by current science. Evidence is preliminary, coming from small studies and case reports that suggest possible symptom improvement when ketosis is achieved under medical supervision, but large, randomized trials showing clear benefit over medication alone are lacking. The Stanford study reported most adherent patients improved but had no control group, and researchers caution that keto should supplement rather than replace antipsychotic treatment while more rigorous research is underway.
Health Secretary RFK Jr. claimed the keto diet could cure schizophrenia, a statement experts say greatly overstates early research as he campaigns for real-food eating and new dietary guidelines that favor fats and proteins over carbohydrates.
A long-term ketogenic diet may prevent weight gain but can cause severe metabolic problems such as fatty liver disease and impaired blood sugar regulation in mice, highlighting potential health risks that warrant caution and medical supervision.
A long-term mouse study suggests that while keto diets may promote weight loss, they can also increase blood lipid levels, cause fatty liver, and impair glucose regulation, raising concerns about their long-term safety for metabolic health. Further research in humans is needed to fully understand these risks.
Research from UT Health San Antonio suggests that ketogenic diets may cause harmful cellular changes in male mice but not females, with estrogen providing protective effects, highlighting potential sex-specific responses to the diet.
A mouse study suggests that a ketogenic diet may accelerate aging in males but not in females, possibly due to estrogen's protective effects; further research is needed to see if these findings apply to humans.
A controversial study on the ketogenic diet's effects on cholesterol and artery plaque has sparked intense debate in the nutrition community, with critics questioning its methodology and conclusions, while some advocates see it as challenging long-standing beliefs about LDL cholesterol and heart disease.
Dr. Mehmet Oz and Dr. Michael Roizen discuss the benefits of a healthy keto diet for individuals with Type 2 diabetes, emphasizing the importance of avoiding red and processed meats and focusing on mono- and poly-unsaturated fats from sources like olive oil and fatty fish. They highlight that a low-carb diet can potentially help reduce medication dependency by encouraging insulin production. The article advises eliminating processed carbs and incorporating vegetables for fiber and nutrients.
A study published in Cell Reports found that a ketogenic diet can reduce the severity of multiple sclerosis (MS) in mice by altering gut bacteria and their metabolites. The research suggests that molecules produced by gut bacteria, such as beta-hydroxybutyrate (BHB) and indole-3-lactate (ILA), play a crucial role in these benefits. This discovery opens the possibility of using BHB and ILA supplements as a more manageable treatment for MS, potentially bypassing the need for a strict keto diet.
Researchers at UC San Francisco have found that the keto diet may help treat autoimmune disorders like multiple sclerosis by increasing the production of anti-inflammatory compounds. In a study with mice, the diet led to higher levels of the ketone body β-hydroxybutyrate (βHB), which in turn prompted the gut bacterium Lactobacillus murinus to produce indole lactic acid (ILA). This metabolite blocked the activation of T helper 17 immune cells, reducing inflammation. While promising, these findings need further testing in humans.
The ketogenic diet, originally developed to treat epilepsy in children, has become popular for weight loss by emphasizing high fat and low carb intake to induce ketosis. However, experts warn that it is often unsustainable, can lead to nutrient deficiencies, and poses health risks such as heart disease and liver problems. They recommend focusing on long-term, sustainable habits like increased physical activity and a balanced diet rich in fruits, vegetables, and fiber instead.
A study from UT Health San Antonio suggests that long-term ketogenic diets may cause cell aging in organs like the heart and kidneys, but taking intermittent breaks from the diet can prevent these negative effects. Researchers recommend planned breaks to enhance the benefits of a ketogenic diet and avoid potential long-term consequences.
US scientist Professor David Gius suggests taking regular "keto vacations" to mitigate the potential negative effects of a ketogenic diet, such as the accumulation of ageing cells in organs. His study on mice showed that while the keto diet has initial health benefits, prolonged adherence may accelerate organ ageing. Periodically switching back to a standard diet can reduce these ageing cells, indicating that a cycling ketogenic diet might be more beneficial.
