Ketone Drink Makes Muscles Feel More Anabolic — But Doesn't Rebuild Glycogen Faster
Intake of a Ketone Ester Drink during Recovery from Exercise Promotes mTORC1 Signaling but Not Glycogen Resynthesis in Human Muscle

Surprising Findings
Ketone ester didn’t improve glycogen resynthesis despite elevating blood ketones to fasting-level concentrations.
Most assume ketones replace glucose as fuel—so people expected faster glycogen recovery. Instead, ketones boosted signaling without touching energy stores, revealing a completely separate biological pathway.
Practical Takeaways
If you’re already taking protein + carbs after workouts, adding a ketone ester might amplify muscle growth signals—but only if you can tolerate the stomach upset.

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.
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.
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 energy quicker.
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 aren’t just fuel, they help the signal work better.
The ketone drink made half the guys feel sick to their stomach — bloating and nausea — but didn’t change their ketone or blood sugar levels, meaning the side effects aren’t linked to the good effects.
