Well, sex can definitely not be counted as a form of exercise since the calorie loss from it is minimal. However, sex could help you in reducing weight. It’s more an emotional thing. Many of us eat for emotional reasons. When we are depressed or disturbed, we tend to reach out for that plate of food. Having a good sexual relationship gives you a feeling of well being and satisfaction. This reduces your craving for food and thus helps you to keep your weight under control. In addition, an intimate relationship helps you to improve your self-esteem and confidence and thus you are unlikely to indulge in obsessive or binge eating.
