New studies are showing that a more intense exercise can have more unique benefits than a normal or gentle work out. Since these intense workouts are becoming popular and people are starting to believe that the shorter workouts are just as effective as the longer sessions of moderate exercise, a study came about. The study would compare the effects of easy versus exhausting exercise to a person's desire to eat. It was very clear that these more vigorous exercises were effective with things such as aerobic fitness, blood pressure, and insulin sensitivity; However, they weren't sure how it would or if it would effect weight control. 

So with the study they recruited 17 overweight but healthy men who would show up at the University's exercise lab on 4 different days. "One of these sessions was spent idly reading or otherwise resting for 30 minutes", next day  "the men rode an exercise bike continuously for 30 minutes at a moderate pace". Then the  "third session was more demanding, with the men completing 30 minutes of intervals, riding first for one minute at 100 percent of their endurance capacity, then spinning gently for 4 minutes." Moreover, "The final session was the toughest, as the men strained through 15 seconds of pedaling at 170 percent of their normal endurance capacity, then pedaled at barely 30 percent of their maximum capacity for a minute, with the entire sequence repeated over the course of 30 minutes." 

So they compared this by drawing blood before and after exercise and rest to check for levels of a particular substance that's know to influence appetite. So after the most intensive exercise, food was supplied, and the men consumed less than they did after the more moderate exercise. The results of this study was parallel to another study done on appetite and exercise intensity which made the results more valid. This helps display how exercise and eating can go hand-in-hand when it comes to remaining healthy and not being overweight.
