What happens when you swap butter for sugar?
Adverse effects on insulin secretion of replacing saturated fat with refined carbohydrate but not with monounsaturated fat: A randomized controlled trial in centrally obese subjects

Surprising Findings
Replacing saturated fat with refined carbs reduced insulin secretion relative to glucose — even though glucose levels rose higher.
Most assume more sugar = more insulin. This shows the opposite: the pancreas under-released insulin for the sugar load, suggesting early beta-cell fatigue — a red flag for metabolic disease.
Practical Takeaways
If you're trying to reduce saturated fat, swap it with monounsaturated fats (olive oil, avocado, nuts) instead of refined carbs (bread, pastries, sugary cereals).

If you swap out foods like butter and cheese for things like white bread and sugary snacks, it might raise your blood sugar and fat levels after meals, which could make your heart more likely to get sick.
If you swap out a small amount of fatty foods for sugary or starchy ones for six weeks, your body releases less insulin after eating—even though your blood sugar goes up the same—which might mean your pancreas isn’t working as well.
If you swap out a small part of the fatty foods you eat—like butter or cheese—with healthier fats like olive oil or avocado for six weeks, it won’t hurt your body’s ability to manage blood sugar.
If you're overweight around the middle and eat a meal full of carbs, your blood sugar and insulin spike more than if you ate a meal with lots of butter or olive oil—but your body doesn’t make as much insulin for how much sugar is in your blood.
