The Claim
Muscle glycogen stores are fully replenished within 24 hours on low-carbohydrate diets, and high carbohydrate intake is not required for recovery between resistance training sessions.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
On a low-carbohydrate diet, muscle glycogen is completely restored within 24 hours after resistance training, and consuming large amounts of carbohydrates does not improve this recovery process.
See the scientific wording
Muscle glycogen stores can be fully replenished within 24 hours on low-carbohydrate diets, rendering high carbohydrate intake unnecessary for recovery between resistance training sessions.
When carbohydrates are low, the body breaks down muscle protein and fat to make new sugar, which it then stores in muscles as glycogen, allowing muscles to refill their energy stores even without eating carbs.
What the research says
1 studyStudy: Metabolic characteristics of keto-adapted ultra-endurance runners.
The study found that ultra-runners on low-carb diets used and recovered muscle glycogen similarly to those on high-carb diets after a 3-hour run — but only after 2 hours, not 24, and not after weightlifting. So it doesn't prove low-carb diets work just as well for gym recovery.
