Men who have overweight or obesity tend to have higher levels of triglycerides in their blood after fasting and after eating, compared to men with normal body weight, no matter whether they eat a meal high in fat or high in carbohydrates.

If you have metabolic issues like high blood sugar or cholesterol, eating foods that swap out butter or fatty meats for carbs (like bread or rice) or for olive oil and avocados doesn’t make a noticeable difference in your blood fat levels after meals.

In men with overweight or obesity, eating a single meal high in fat leads to higher levels of triglycerides and homocysteine in the blood after eating than eating a meal with the same number of calories but high in carbohydrates.

Almost everyone who switched to a low-fat, high-carb diet saw their blood fat levels go up—only one person didn’t, which means this effect happens in nearly all people.

Intermittent fasting might help lower triglycerides a little more than regular calorie cutting in people with overweight or obesity, but the difference is so small that scientists can't say for sure it's not just due to chance.

When healthy young men only eat between noon and 8pm for five days straight, it doesn't change their baseline blood fat levels
