After eating mostly fat for three days, healthy young men released more of a gut hormone (GLP-1) that helps control blood sugar when they drank sugar water, even though their blood sugar still went higher.

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

Scientists gave men a high-fat, low-carb diet for 3 days and found their bodies released more of a hormone called GLP-1 after drinking sugar water, compared to when they ate a normal diet — exactly what the claim says.

Even though the body released more of a sugar-controlling hormone after eating fat for three days, blood sugar still went higher—meaning the hormone wasn’t strong enough to fix the problem.

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.

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.
