A newly published study by the University of Bath revealed that individuals who exercise before consuming breakfast burn more fats compared to those who replenish after. The results were based on six weeks program composed of 30 men who either categorized as obese or overweight.
The participants were grouped into two — those who ate breakfast before exercise and those who ate after — to determine which method burns more fats. Take note, the participants of the study did not make any significant lifestyle changes.
The Journal of Clinical Endocrinology & Metabolism detailed that those who work out before breakfast burns fat twice compared to those who ingest after.
The increased fat burning during a workout from people who fasted overnight is said to be due to the low levels of insulin in the body. The researchers pointed out that since the body is exercising with no fuel, it looks into its stored carbs. And, once those are burned, the body turns to fat cells.
During the six week program, both groups lost a similar amount of weight. The difference, however, the eat before group burned more fats than the eat after group.
When the research subjects skipped meals before they start exercising, their muscles were reactive to insulin — the hormone that controls high blood sugars. With that being said, the body reduces the risk of developing heart diseases and diabetes.
“The group who exercised before breakfast increased their ability to respond to insulin, which is all the more remarkable given that both exercise groups lost a similar amount of weight and both gained a similar amount of fitness,” said Javier Gonzalez, an associate professor in the department for health at the University of Bath and exercise physiologist.
Gonzalez has also co-authored a similar study at the same institution in 2017. The study focused on 10 men who burned more fat because their blood sugar levels were low after fasting. However, in this study, men who ate breakfast first burned more calories.
There was also another study made in 2010 that had similar results. According to the study, 28 physically healthy men were involved and divided into groups.
One of them did not go through any exercise at all. Two other groups had to go through running and cycling four times a week. Another group was asked to eat after working out while another was assigned to eat after their exercises.
The results showed that those who failed to workout gained weight. Those who also ate breakfast before their workout managed to gain weight. The group who managed to maintain their weight and lose fat with normal blood sugar levels were the ones who worked out with an empty stomach.
In conclusion, exercising before eating imposes a positive effect on the overall health of a person. To avoid the breakdown of muscle tissues, it’s important to rehydrate, replenish, repair, and reinforce.
