In lab-grown muscle cells, adding ketones along with leucine (a muscle-building amino acid) makes the 'grow' signal way stronger and actually increases how much protein the cells make — ketones...

Similar Assertions

Taking leucine — a protein building block — might turn on muscle-building signals in your muscles, but if you're already training and eating enough protein, it won't actually make you stronger, bigger, or recover faster.

When trained guys drink a special ketone drink after a tough leg workout (and also eat protein and carbs), their muscles send stronger 'grow' signals than when they drink a fake version — even though their insulin levels are the same.
