A new study by researchers at the University of Bath and the University of Birmingham sheds light on what's better: breakfast before or after a morning workout? Although there is no solid rule that is preferred, the study found that pre-breakfast exercise can dramatically reduce the chances of developing two common and serious health conditions.
People who have a regular sleep schedule end up fasting overnight, which means that they spend several hours or more between their last meal of the previous day and their first meal of the current day. During this time, blood glucose levels drop, leading to decreased levels of the hormone that regulates blood sugar, insulin.
Exercise before breakfast means that activity will continue until insulin levels are lower, indicating that the study is a good thing: this has doubled the amount of body fat burned compared to people who exercise after breakfast . It didn't make any difference in weight loss, but it had some other notable effects.
Based on a six-week study, researchers found that pre-breakfast exercises dramatically improved the body's ability to control blood glucose levels by increasing insulin sensitivity. Improving blood glucose control, the team noted that pre-breakfast workouts can reduce the risk of heart disease and type 2 diabetes.
There is a profound improvement in health, although both groups of participants experience the same level of weight loss and fitness gain. The study included only men and went on and on for six weeks, indicating that exercising before the first meal of the day could have many benefits, despite zero change in effort.
