According to a study, intermittent fasting can reduce triglyceride levels by as much as 40% after meals in healthy but overweight subjects. The study was conducted on a group of individuals who ate normal meals for five days of the week and then fasted or ate low-calorie meals for two days. The findings of the study indicate that intermittent fasting is more effective at reducing triglyceride levels than daily calorie-restricted dieting. However, you must consult with your doctor before embarking on a fasting or dieting regimen.
