Exercise after meals to reduce the harm of fatty foods
The results show that walking and light exercise an hour after taking fatty food lowers the level of triglycerides in the blood, which usually occur after eating fats. What’s more, exercising after eating is more effective in reducing triglycerides than exercise before eating.
The study involved only 10 people, men and women, which the scientists measured triglyceride levels after they ate fatty foods (38% fat). On the first day people were engaged in physical activity for an hour before a meal, the second day ‒ an hour after. On the third day the participants in the study only ate.
In a day without physical education, two hours after lunch, their triglyceride levels rose from 66 mg/ DL (milligrams per deciliter) to 172 mg/ DL. The normal level is 150 mg/ DL and below (on empty stomach).
When people exercise before dinner, their triglyceride levels increased to 148 mg/ DL. When they exercised after a meal, their triglyceride levels increased to 131 mg/ DL.
Six hours after eating fatty foods, triglyceride levels of all participants were approximately the same, regardless of whether they were engaged exercise that day or not. However, according to the researchers, even a temporary elevation of triglycerides after a fatty meal may eventually lead to cardiovascular diseases.
Exercise after fatty foods accelerate the process of absorption of fat by the body, thereby reducing triglyceride levels, researchers say. And it’s a good excuse to go for a walk after a heavy meal.
