Researchers at Loughborough University in the U.K. found a probable reason why this occurs. In their study, they found that people increase their portion sizes by about a quarter after a workout as a way to "reward" themselves for breaking a sweat. Many often eat back all – if not more than – the calories they worked so hard to burn. Exercise then becomes counterintuitive in this case, as it could lead to weight gain for people with this mindset.
For the study, the researchers recruited 40 participants who were tasked to take part in an aerobics class at least three times a week. After measuring the participants' weights, they were asked how much they eat after a workout and on a rest day.
The researchers found that regular exercise led to an initial weight loss. However, the rate of weight loss declined, or weight became stable over time as the participants chose to eat a larger portion size meal, particularly a 24 percent increase in energy content of food served after a workout session. They explained that this increase might diminish the negative energy balance induced by exercise. Consequently, this may undo any weight loss with regular exercise training.
In addition, the researchers found that the volunteers increased their lunch-time portions by 150 calories after exercising. They warned that eating more during dinner would more than outweigh any benefit of exercising.
They also found that the consumption of chocolate increased by 20 percent. This pattern was seen more commonly in women than in men.
The findings of the study suggested that aerobic exercise may affect meal planning, at least in those who exercise regularly, which may be responsible for the stabilization of weight loss. For this reason, the researchers stressed the importance of combining exercise with a healthy diet when trying to effectively shed off some pounds.

One of the reasons why you tend to be hungry after working out is because exercise increases appetite. Reduced glycogen stores, dehydration, and inadequate pre-workout fuel are several other reasons why you get hungry after exercising.
