Exercises are a major contributor to fat lose. Especially doing like 20 sit ups daily for one month can contribute a lot . I personally have tried this and seen its results although its very hard to manoeuvre during the first times. Also exercises like running short distances can help. What you need yo avoid during exercises is the marathon running and don't exercise for long. Anything good has got its disadvantages as well. This can affect your health and also psychology. Also ensure you check on your diet. Eat diet that's full of proteins, vegetables and fruits. Eating five meals a day is highly recommendable if you need to cut your belly fat. By five meals, I don't mean you have heavy meals, no, just slight meals are okay. This will help in reducing cravings for the junk which is the major contributor to the belly fat. Finally, drink a lot of water like 6 to 8 glasses a days. Water helps in weight loss and also increases the rate of the metabolism.
