The Claim
In elite race walkers, a 3-week ketogenic low-carbohydrate, high-fat diet (LCHF) providing less than 50 grams of carbohydrate per day and 78% of energy from fat is associated with markedly increased whole-body fat oxidation during exercise, with peak fat oxidation rates reaching 1.57 ± 0.32 grams per minute at approximately 80% of maximal aerobic capacity, representing one of the highest sustained fat oxidation rates ever recorded in endurance athletes.
What the research says
Supports is higher
Support is ahead, but a single strong opposing 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.
Elite race walkers who eat a super low-carb, high-fat diet for 3 weeks start burning fat like crazy when they exercise — one of the highest fat-burning rates ever seen in top athletes.

What the research says
1 studyThe study found that elite race walkers on a strict low-carb, high-fat diet burned fat at very high rates during exercise, just like the claim says.
