Does eating fewer carbs make your blood fats go up?

Consuming large amounts of carbohydrates leads to prolonged higher levels of glucose in the blood because the body converts carbohydrates to glucose faster than it can remove it from the bloodstream.

In people with type 1 diabetes, eating a diet with 40% low-glycemic carbohydrates raises blood levels of free fatty acids and triglycerides more than eating a diet with 60% high-glycemic carbohydrates, even when blood sugar levels stay similarly stable.

For adults with type 1 diabetes, changing the glycemic index of foods does not meaningfully alter blood glucose patterns over four weeks, whether they eat a lower or higher amount of carbohydrates.

For adults with type 1 diabetes, eating a diet where 40% of calories come from carbohydrates does not lead to higher levels of ketones in the blood compared to eating a diet where 60% of calories come from carbohydrates. This suggests that moderately reducing carbohydrate intake does not trigger ketosis or raise the risk of ketoacidosis under controlled conditions.

For adults with type 1 diabetes, changing what they eat for four weeks does not lead to a measurable change in fructosamine, a marker of average blood sugar levels over the past few weeks.
