Substantial Early Changes In Bone And Calcium Metabolism Among Adult Pharmacoresistant Epilepsy Patients On A Modified Atkins Diet

Researchers studied whether the modified Atkins diet (MAD), a less restrictive version of the ketogenic diet, affects bone health and calcium metabolism in the body. They followed 53 adults with drug-resistant epilepsy who followed the MAD for 12 weeks, comparing them to 28 similar patients who continued their regular diet. The researchers measured various markers of bone health, calcium levels, vitamin D, and hormones before and after the 12-week period.

The study found significant changes in the MAD group's bone and calcium metabolism. Participants experienced decreases in parathyroid hormone (which regulates calcium), calcium levels, vitamin D in its active form, and markers that indicate bone turnover - essentially how quickly bone tissue breaks down and rebuilds. However, they did see an increase in stored vitamin D levels. These changes were most pronounced in younger participants (under 37) and those with higher body mass indexes, while sex and seizure medications didn't influence the results.

These findings are important for metabolic health because bone metabolism is closely connected to overall metabolic function. The changes occurred relatively quickly - within just 12 weeks - suggesting that ketogenic-style diets can rapidly alter how the body processes calcium and maintains bone health. While this study focused on epilepsy patients, the metabolic changes observed could be relevant for anyone considering a ketogenic diet for weight loss or other health benefits.

From a clinical standpoint, these results suggest that people following ketogenic diets may need closer monitoring of their bone health markers and calcium levels, particularly during the initial months of the diet. Healthcare providers should consider baseline and follow-up testing of these markers when patients begin ketogenic dietary interventions.
