After eating a high-fat, low-carb diet for three days, the body releases more of a gut hormone called GLP-1 when you drink sugar water — even though blood sugar goes higher.

Similar Assertions

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.

90%

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.

Eating very low-carb, high-fat food for just three days makes blood sugar spike higher after drinking a sugary drink, compared to eating a normal diet.

82%

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.

After eating a high-fat, low-carb diet for three days, the pancreas releases less insulin right after you drink sugar — even though blood sugar goes up.
