Dragon fruit and weight loss

Macronutrients and micronutrients

When you look at dragon fruit's nutrition, you can see that it is a fruit that can help you lose weight. Since it's mostly water, it ensures that even though you eat a lot of food, you only take in a few calories. It makes you feel fuller, helps your stomach, and keeps your skin glowing, which is especially helpful when you're dieting.

The main source of energy in dragon fruit is carbohydrates. However, it's the fruit's high dietary fibre level that makes it stand out when it comes to weight loss.3 Food high in fibre benefits the body in ways beyond digestion. Since it makes you feel full for longer periods, you're less likely to overeat or snack on things you don't need. In addition, foods high in fibre can help keep blood sugar levels steady, which can help dieters avoid giving in to their sugar urges.

Even though Dragon fruit doesn't have a lot of protein like some other foods, it has a good amount in comparison to other fruits. This helps repair muscles, which is important if you're working out to lose weight. Dragon fruit is low in fats, but the ones it does have are mostly good unsaturated fats that can help your heart stay healthy while you lose weight.4

Essential vitamins and minerals

There are more ways that dragon fruit can help you lose weight than just its macronutrients. For example:

Vitamin C: Vitamin C and E are antioxidants that fight off free radicals in our body, which can otherwise damage cells and contribute to chronic diseases. They not only help the defence system but also speed up the metabolism.5 To lose weight, you need to make sure that your metabolism works well so that your body burns calories efficiently.

Vitamin E: This is another antioxidant found in dragon fruit, and can help reduce inflammation in the body. Chronic inflammation can make it hard to lose weight, which is why vitamin E is so important.4

B-Vitamins: Dragon fruit has a lot of B-vitamins, especially B3 (niacin), which can help keep blood sugar levels stable and speed up your metabolism, which are both important for managing your weight.

Magnesium: Magnesium helps the body's enzymes do many things, including processes that speed up the metabolism. Having the right amount of magnesium also helps you sleep well, which is very important for losing weight.6

Iron: Iron helps oxygen get to all parts of the body, so your muscles and metabolic processes get the oxygen they need to burn the most calories.

Calcium: Calcium is important for bones, but it also helps store and break down fat. If you get enough calcium, your body will store less fat and break down fat more efficiently.6
