Excercise can help to decrease your appetite.
Fad diets, pills, surgeries and herbal supplements are all ways that people try to control their raging appetites to lose weight. Few would assume that exercise itself works as an appetite suppressant in many cases. While exercise is always healthy, certain types work better than others at decreasing appetite.
Resistance Exercises
Fitness activities like weight lifting and calisthenics burn fat, build muscle, strengthen bones and can lead to decreased appetite. Try lifting free weights or use machines like the "Bowflex" or other resistance equipment.
Keep It Hot
Cardio exercises like jogging, running, elliptical training and spinning increase body temperature, which in turn increases how many calories you burn.
Exercises that do not increase body temperature, such as swimming or working out in the cold (in which the body has to work to maintain its regular temperature) still burn ample calories, but will leave you feeling hungry after the activity is complete.
Intensity
Exercise intensity can also affect whether you'll be stimulating or decreasing your appetite after doing the activity. Higher-intensity activities have better appetite-suppressing effects than lower-intensity ones.
Endorphins
An article in the "Boston Globe" explains that decreased appetite post-exercise is caused by naturally-occurring brain chemicals called endorphins. In addition to decreasing appetite, endorphins can increase pain tolerance and induce feelings of euphoria during and after exercise.
Ghrelin and Peptide YY
Ghrelin and Peptide YY, two hormones that are excreted during intense exercise, also help to reduce appetite. Aerobic exercise like running on a treadmill or elliptical cause the body to excrete the greatest amounts of both Ghrelin and Peptide YY.
