After a hard workout, ketone drink helps your muscles calm down their 'energy alarm' (AMPK) twice as fast as a placebo, likely because ketones give your muscles another fuel to burn and restore...

Drinking ketone drink after a hard workout doesn’t help your muscles refill their energy stores any faster than drinking a fake drink — even if your blood ketones are high.

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.

After a single workout with weights, your muscles temporarily slow down their protein-building process, and this might be because a specific energy-sensing molecule (AMPK) gets more active and tells the building machinery to take a break.

Even though your muscles get a signal to slow down energy use after lifting weights, they still keep building protein—like your body’s repair crew is ignoring the ‘slow down’ sign because the ‘build up’ signal is stronger.
