To explain quickly, SeroLean is a potent formula that contains a specific blend of powerful natural ingredients, that have been clinically shown to help your body naturally produce much needed serotonin, which – when lacking – can be responsible for runaway hunger, emotional overeating, carb cravings, mood, stress and sadness. Here’s the serotonin process in detail: Serotonin signals the brain when it’s had enough food. This is called the “full belly mechanism.” Without serotonin, the brain senses its food needs are not being met, and goes into a “red alert” sending out powerful signals to your “appetite control center” telling your body to “start eating fast” and “stock up on carbohydrates.”. Low serotonin levels can lead to carbohydrate cravings, and high carbohydrate intake can lead to weight gain. With more serotonin in your body, your “appetite control center” can receive strong signals indicating that enough food has been consumed. This can “switch off” food cravings and create a feeling of fullness. This can result in fewer calories during the day without severe hunger and cravings … leading to potential faster weight loss.
