Strong Support

When healthy young men ate the same number of calories but swapped carbs for fat for just three days, their body’s response to sugar changed—blood sugar went up, insulin came out slower, and a gut hormone went up.

Short-term low carbohydrate/high-fat diet intake increases postprandial plasma glucose and glucagon-like peptide-1 levels during an oral glucose tolerance test in healthy men

Cross-Sectional Study
Human
2012 Aug

The study gave men a high-fat, low-carb diet for 3 days and found that their blood sugar and GLP-1 levels went up after drinking sugar water, while their insulin response dropped — just like the claim said it would.

Similar Assertions

After eating just three days of mostly fatty food instead of carbs, healthy young men had higher blood sugar spikes when they drank a sugary drink, meaning their bodies handled sugar less efficiently.
