An 8-week very-low-calorie diet drops liver fat as ketones and TCA intermediates rise

In a pilot of women with obesity and metabolic dysfunction-associated steatotic liver disease, an 8-week very-low-calorie diet cut weight about 11% and hepatic controlled-attenuation-parameter fat without changing stiffness. Ketones go up, amino acids go down, and CAP change tracks amino acids up and ketones plus tricarboxylic-acid-cycle intermediates down. A few circulating microRNAs move with CAP and HOMA-IR.

Finding. Eight weeks of a very-low-calorie diet in women with obesity and MASLD, no diabetes, took off about 11% of body weight and a lot of liver fat on controlled attenuation parameter. Stiffness and enzymes sat still. Deb, Correia and colleagues see ketones rise and amino acids fall, the look of fat oxidation and a catabolic state. The more CAP fell, the more ketones and tricarboxylic-acid-cycle intermediates moved the other way. A few circulating microRNAs, not the whole miRNome, travel with CAP and HOMA-IR.

Score 67. Human, imaging plus TCA/ketone metabolites. Confidence is medium: pilot, blood not liver mitochondria, abstract cut off.

What to do with it If you map diet-driven hepatic mitochondria, this is a CAP-versus-TCA-intermediate correlation. Do not write fibrosis reversal.
