Why eating fewer carbs for 3 days made blood sugar spike 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

When healthy young men ate mostly fat and very few carbs for just 3 days, their blood sugar went up more after drinking sugar water, even though their body made more of a hormone called GLP-1 that usually helps control blood sugar.

Reduction in dietary carbohydrate intake improves postprandial glycemic control and lowers circulating triglyceride levels in humans.
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.
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.
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 body releases more of a gut hormone called GLP-1 when you drink sugar water — even though blood sugar goes higher.
