Food cravings between meals are usually caused by stress, anxiety or emotional distress. The spike in serotonin levels due to the Garcinia Cambogia intake usually lifts your mood and helps reduce food cravings. Garcinia is an appetite suppressant, so it helps you reduce your calorie intake. You may find that you can go longer between meals without snacking as Garcinia Cambogia increases satiety and leaves you feeling full for longer. The HCA content in Garcinia increases the conversion of carbohydrates for energy and it also revs up your metabolism allowing you to become more energetic and physically active. All this contributes to Garcinia Cambogia's effectiveness as a weight-loss supplement.
