The Claim
In humans, post-endurance exercise consumption of a low-carbohydrate diet preserves insulin sensitivity, whereas consumption of a high-carbohydrate diet reduces insulin sensitivity compared to the low-carbohydrate condition.
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 endurance exercise, eating a low-carbohydrate meal maintains insulin sensitivity, while eating a high-carbohydrate meal reduces insulin sensitivity.
See the scientific wording
In humans, consuming a low-carbohydrate diet after endurance exercise preserves insulin sensitivity, while a high-carbohydrate diet blunts this benefit, mirroring findings observed in rats.
After exercise, eating a lot of carbohydrates causes excess sugar to flow into a specific metabolic pathway that modifies key proteins involved in insulin signaling. These modifications block the movement of glucose transporters to the cell surface, preventing muscle cells from taking up glucose in response to insulin.
What the research says
1 studyStudy: Seeking the Mechanism for Reversal of Enhanced Insulin Sensitivity after Acute Exercise
After a workout, eating lots of carbs makes your body lose the improved insulin sensitivity you gained, while eating fewer carbs helps keep that benefit. This study shows that in people, just like in rats, too many carbs after exercise undo the good effects.
