Less body fat does not always mean better metabolic health
What a rare genetic disorder reveals about fat storage and mitochondrial function.
What the research found
Human biopsies and mouse experiments linked LMNA-related lipodystrophy to disturbed lipid pathways, inflammation and regional adipocyte loss. Established human disease combined lower total fat with worse glucose and triglyceride measures. Direct respiratory impairment was demonstrated in particular mouse fat depots.
What it does not establish
This small genetic-disease study does not show that ordinary dieting produces lipodystrophy, or that additional calories treat it. Human gene-expression changes are not direct measurements of mitochondrial ATP output.
A research question for EPK
EPK should test function and fat distribution alongside mass. A useful outcome set would include strength, glucose regulation, liver fat where feasible, and regional body composition. These are proposed measurements, not demonstrated EPK benefits.
