While most appetite suppressants work by altering your levels of catecholamine or serotonin, there are some that behave differently. For example, cinnamon lowers your blood sugar levels, which in turn alters your insulin levels and helps you to control your appetite. Your body is a complex machine, and there are many different factors that dictate when you feel hungry. It’s important that you listen to your body and try a few different supplements to figure out what works for you. Just because your best friend swears by cayenne pepper, it does not mean that it will be the perfect supplement to help you on your fat loss journey.
Appetite suppressants can be incredibly effective at promoting short and medium term weight loss, however they should not be taken long term. It is possible to develop a tolerance to appetite suppressants. Most people find that their weight loss plateaus after six months. It is best to use these supplements in addition to a calorie controlled diet. Once you have taught yourself how to exercise good portion control and manage your diet, you may want to consider stopping the use of diet aids for a little while. You can reintroduce them if you struggle to shed the last couple of pounds, but try not to depend on them.
