What is better for health; the exercise in empty stomach or after eating? It is one of the most age-old questions for physicians as well as general public. While most people believe empty stomach is better for productive workouts, some people consider after eating exercise to be more effective than the former one. If like those thousands of people, you also have been wondering if it is better to eat or keep the stomach empty before a workout session, then the new study has the right answer for you. A team of international researchers has found that workout on an empty stomach is much better for long-term health benefits in contrast to after eating exercise.
In the study, investigators from the University of Bath in the UK conducted a thorough examination of the effects of eating versus fasting on gene expression in adipose or fat tissue in response to work out and found that exercise in empty stomach is much more efficient and powerful than the contrary option. Work out on an empty stomach is likely to help cut more amount of body fat in comparison to the post eating workout. It is also proven to stimulate your metabolism and boost your health for a long-term basis, suggests the new study.
For the experiment, researchers from the University of Bath in the UK took a group of overweight males into account and asked them to walk for 60 minutes daily at 60% maximum oxygen intake on an empty stomach. Plus, the participants were also requested to take two hours of the walk after eating a high-calorie carbohydrate-rich breakfast. The research team also collected multiple blood samples from the participants after eating and fasting, after a workout session. They also took adipose tissue samples right one hour before and one hour after walking.
After analysing two trials and their reports, the researchers found that gene expression in the adipose tissue significantly fluctuated in the both trials. They also found that the expression of two DNAs – PDK4 and HSL, improved when the men exercised in empty stomach and went down when they ate before a workout session.
According to Dylan Thompson, the lead author of the study, from University of Bath, “HSL naturally boosts when adipose tissue draws on the stored energy to shore up amplified activity, such as exercise.”
