Do Appetite Suppressants Really Work?

Anyone who has ever tried to lose weight knows that one of the hardest parts is fighting cravings and hunger pangs. It seems like no matter how hard you try, your body is working against you. You’re always thinking about food, and it’s tough to stay on track. That’s where appetite suppressants come in.

Appetite suppressants are designed to help you feel full so that you eat less and lose weight. There are a lot of different kinds of appetite suppressants on the market, from pills to powders and shakes. But do they really work? Let’s take a look.

How Appetite Suppressants Work

Most appetite suppressants work by stimulating the sympathetic nervous system, which releases chemicals that tell the body to stop eating. Some work by inhibiting the production of hunger-signaling hormones like ghrelin. And others simply make you feel fuller so that you eat less.

There are a lot of different ingredients in appetite suppressants, and they all work differently. Some common ingredients include:


Caffeine is a stimulant, so it has an energizing effect. It also inhibits the hormone adenosine, which makes you feel sleepy. Caffeine can help you feel more awake and alert, and it may also help to reduce your appetite.

Green tea extract: 

Green tea extract is high in antioxidants, which can help protect your cells from damage. It also contains caffeine, which can help to boost your metabolism and reduce your appetite.

Conjugated linoleic acid (CLA): 

CLA is a type of fatty acid found in meat and dairy products. It’s thought to have a number of health benefits, including reducing inflammation and boosting metabolism. CLA may also help to reduce your appetite by increasing levels of the hormone GLP-1. 

Do Appetite Suppressants Really Work?

There is some evidence to suggest that appetite suppressants can help you lose weight, at least in the short term. One study showed that people who took an appetite suppressant lost 5% of their body weight over 12 weeks compared to people who didn’t take an appetite suppressant. However, it’s important to note that this study was sponsored by a company that makes an appetite suppressant supplement, so it may not be completely unbiased. 

Additionally, there are some potential side effects associated with taking appetite suppressants, including headaches, anxiety, insomnia, and high blood pressure. So if you’re considering taking an appetite suppressant to lose weight, it’s important to talk to your doctor first to make sure it’s safe for you. 


If you’re struggling with cravings and hunger pangs while trying to lose weight, then an appetite suppressant may be right for you. These supplements can help you feel fuller so that you eat less and lose weight; however, they come with some potential side effects like headaches and anxiety. Talk to your doctor before taking any type of supplement for weight loss to make sure it’s safe for you!
