The Claim
A 6-week ketogenic diet was associated with a reduction in skin sodium concentration from 16.6 ± 2.1 mmol/L to 12.6 ± 2.1 mmol/L and in medial gastrocnemius muscle sodium concentration from 20.5 ± 0.9 mmol/L to 16.7 ± 0.7 mmol/L in three healthy individuals, as measured by 7-T 23Na MRI.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In three healthy people, following a ketogenic diet for six weeks was linked to lower sodium levels in the skin and calf muscle, as measured by a specialized MRI scan.
See the scientific wording
In three healthy individuals, a 6-week ketogenic diet was associated with a reduction in skin sodium concentration from 16.6 ± 2.1 mmol/L to 12.6 ± 2.1 mmol/L and in medial gastrocnemius muscle sodium from 20.5 ± 0.9 mmol/L to 16.7 ± 0.7 mmol/L, as measured by 7-T 23Na MRI.
When the body burns fat for fuel instead of carbs, it produces ketones that signal the kidneys to release more sodium into the urine. This lowers the total amount of sodium in the blood, which causes sodium to move out of skin and muscle tissues into the bloodstream to balance the levels, resulting in less sodium stored in those tissues.
What the research says
1 studyStudy: A KETOGENIC DIET REDUCES TISSUE SODIUM CONTENT: AN EXPLORATORY STUDY
In three healthy people, scientists used a special MRI scan to measure salt in their skin and leg muscles before and after eating a low-carb ketogenic diet for six weeks. The scans showed that salt levels went down in both places, which matches exactly what the claim says.
