Exercise Before Meal

A study suggested that taking a long walk before a fatty meal can reduce the effects of high fat intake on blood vessel function. Eating food high in fats transiently increase fat and triglycerides levels of the blood. A recent research showed that a rich meal could temporarily impair the function of the endothelium (inner lining of blood vessels).

Another study reported that moderate exercise could blunt these effects in both thin and obese middle-aged men. In this study, 20 men ate a rich meal including whipping cream, chocolate and a whopping 80 g of fat under different conditions. In one condition, the men walked 90 minutes on the treadmill the day before meal. In another, there was no exercise.

Researchers found that the men’s post-meal triglycerides levels rose to lesser degree when they exercised before the meal. Moreover, better blood vessel function was found as compared with that with no exercise. Researchers could not clearly figure out how pre-meal exercise could counter the effects of fatty meal. However, they suggested that activity may help lowering blood fat levels, giving less opportunity to fat particles to interact with the blood vessel walls.

The duration of exercise need not be very long. The researchers further pointed out that shorter exercise sessions might also be helpful for the blood vessel function. It was previously found that 30 minutes of activity could lower post-meal blood fat levels.

Exercise can lower the risk of developing heart disease as well as other diseases. It is a healthy lifestyle that should not be ignored. If time permitted (or rather you should force yourself to squeeze some time out of your “busy schedule”), take up a simple program: walk for 3 km or 5000 steps per day, at least 5 times a week. And if you do believe the findings from the above studies, schedule it before meal.
