Researchers recruited healthy, active young men and fed them a bad diet for six weeks. A group of them that exercised before breakfast gained almost no weight and showed no signs of insulin resistance. What’s more, they burned the fat they were taking in more efficiently.

According to the New York Times:
“Working out before breakfast directly combated the two most detrimental effects of eating a high-fat, high-calorie diet. It also helped the men avoid gaining weight.”

New Study: LESS Cardio Gives Better Results

Many experts “recommend that children and teenagers exercise one hour every day and adults get a weekly minimum of two hours and 30 minutes of moderate intensity physical activity.”

“This could be activities such as brisk walking, dancing, gardening) or one hour and 15 minutes of vigorous activity (jogging, aerobic dancing and jumping rope,” CNN reported.

However, a new study in the Journal of Physiology found that about 20 minutes of high-interval training provided the same benefits of longer exercise sessions that focused on endurance training.

As CNN reported, “The study suggested that quick, high-interval training may represent an alternative to endurance training to improve metabolic health and reduce the risk for chronic diseases.”
