The Claim
A single high-glycemic carbohydrate meal containing 88% carbohydrate reduces skeletal muscle pyruvate dehydrogenase kinase (PDK) activity by 56% within 3 hours in healthy men following a 6-day high-fat diet, returning PDK activity to near-baseline levels.
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.
After six days of eating a high-fat diet, consuming one meal that is 88% carbohydrates causes a 56% drop in skeletal muscle PDK activity within three hours, bringing the activity level back to what it was before the high-fat diet.
See the scientific wording
A single high-glycemic carbohydrate meal (88% carbohydrate) rapidly reduces skeletal muscle PDK activity by 56% within 3 hours in healthy men after a 6-day high-fat diet, returning it to near-baseline levels.
After a high-fat diet, muscle cells rely heavily on fat for energy, which builds up molecules that block sugar use. When a large carbohydrate meal is eaten, blood sugar and insulin rise quickly. Insulin turns on enzymes that remove a chemical tag from the sugar-processing machine, turning it on. At the same time, the buildup of fat-derived molecules starts to decline, removing their block on the machine. Together, these changes cause the blocker enzyme to drop in activity, allowing sugar to be used again.
What the research says
1 studyAfter eating mostly fat for a week, a muscle enzyme that blocks sugar use goes up. But after one big carb meal, that enzyme quickly drops back down to normal levels within three hours.
