Dieticians claim that it is better not to start a sport if you don’t mean to take regular exercises because irregular exercises promote obesity. Actually, experts at the Lawrence Berkeley National Laboratory have come to that point. They discovered that irregular physical exercises with long intervals resulted in putting on weight faster than if a person wouldn’t do them at all.

What’s more, researches managed to find out that it would be harder to lose the weight you gained that way. Scientists say you have to be physically active year-round and avoid seasonal pauses to slim effectively. For those who feel they can’t manage that regime, it is better not to start a sport at all. The study shows that those who run hard every day and then quit it gain their weight rapidly. Researches say those runners put on four times their weight before trainings.
