When you eat has a profound affect on your energy and mood. There is a tremendous amount of information on this website about leptin and The Leptin Diet, as I am the original author and national leading expert on diet-related information and leptin.

Leptin is a hormone that comes from your stored fat, travels to your brain, and tells your metabolism how fast it can go -- setting the energy production policy for your entire body. In fact, leptin tells your thyroid how fast to set its energy-producing pace. If you snack between meals, eat meals that are too large on a regular basis, or eat after dinner at night you cause leptin problems that are sure to foul up your energy and mood.

Another hormone coming out of your fat is called adiponectin, a hormone that helps leptin do its job properly, especially regarding your blood sugar levels. When you have leptin problems (being overweight = too much leptin),your adiponectin levels start to drop and you crave sweets and carbohydrates. To make matters worse, low adiponectin levels are associated with a really bad mood. This is most likely associated with unstable ups and downs in blood sugar leading to irritability.*

Following the Five Rules of The Leptin Diet is the foundation for solving this problem. Additionally, nutrients that support more stable and natural blood sugar function can really help out your mood. The tip off you may need some help is an expanding waist line, sugar cravings, excess food or carbohydrate consumption -- and trouble staying positive, especially between meals.*
