The main ingredient important for weight loss in cayenne peppers is “capsaicin. This substance is also found in other types of peppers.

Capsaicin is a thermogenic chemical (1). That means that capsaicin may speed up your metabolism and decrease your hunger.

Reducing cravings

In a small study with 15 people consuming red peppers with every meal increased feeling of fullness (2). The study suggests that adding capsaicin to your meals may help you reduce hunger.

More studies with more people are needed to completely confirm this result.

Speeding up metabolism

Another small study examines the effect of fresh chili peppers on metabolic rate. Metabolic rate is the rate of energy expenditure.

The research indeed found that metabolic rate was increased (3).

Another study looked at how dihydrocapsiate increases metabolic rates. Dihydrocapsiate is a capsinoid found in chili peppers. People who took a supplement with this substance for a month raised their metabolic rate by around 50 calories (4).

This last research provides you with a more specific number on what you can expect.

Health benefits of cayenne pepper

Cayenne pepper may also provide you with other health benefits besides losing more weight.

It has anti-inflammatory properties and may improve vascular and metabolic health (5, 6).

How to implement cayenne pepper in your diet

There are multiple ways you can add cayenne pepper in your diet.

You can consume it in its whole form or you can buy powdered cayenne pepper and add it to your meals, into your water or tea, or just pure if you’re up for it.

In terms of dosage you should aim for about 28 grams of fresh chili pepper a day or 1 gram of powdered chili pepper. The dosage of course varies from person to person.

Before you go straight to the big doses, you might want to start small and increase from there. Some people don’t react very well to spicy food.

Cayenne pepper is not for everyone

In certain cases, you want to consult with your primary care provider before you add cayenne pepper to your diet.

For example when you take medication, when you are pregnant or breastfeeding, when you have a surgery coming up and have a history of medical conditions.

The long-term effects of large doses aren’t completely clear. The safe option is to add it to dishes every once in a while instead of taking it daily.

Cayenne pepper may also cause irritation if it comes into contact with your skin and eyes.
