Kalonji Seeds For Weight Loss: What Is The Science Behind It?

If you are on a weight loss journey, you may have heard that adding these seeds to your diet could aid weight loss. But is this theory scientifically backed up? This remains the million-dollar question that we will try to answer today.

There is no scientific material that details the exact mechanisms of how kalonji seeds promote weight loss. But, several compounds are thought to contribute to the possible benefits of kalonji seeds for weight loss. One of them is phytochemicals.

How Do Phytochemicals Promote Weight Loss?

According to a 2016 review, some phytochemicals have been found to reduce adipose tissue growth, appetite, and the differentiation of preadipocytes (2). Additionally, certain phytochemicals have been found to facilitate weight loss by promoting lipolysis and fatty acid oxidation (2).

The review was conducted on phytochemicals in general, not on kalonji seeds specifically, but kalonji seeds do contain phytochemicals. In addition to weight loss, phytochemicals can also have antioxidant, anti-proliferative, anti-inflammatory, anti-carcinogenic, and anti-aging properties.

How Effective Are Kalonji Seeds For Weight Loss?

Of course, everyone wants to consume or use weight loss products with effective results. That said, it is natural to question how effective kalonji seeds aid weight loss. Before we continue, it is important to note that there is no direct mechanism proven on how nigella seeds promote weight loss. Let us keep that in mind.

Is Kalonji Water Good For Weight Loss?

One of the many ways people consume kalonji seeds for weight loss is by having them in warm water. All you have to do is take a glass of warm water and add a pinch of powdered kalonji seeds.

Some people also add the seeds in a combo of warm water, lemon, and honey.

That said, weight loss results are more effective when consuming a low-calorie diet and exercising regularly. These two practices help you sustain a calorie deficit that helps keep the weight off for the long haul.

Besides weight loss, drinking kalonji water has been claimed to enhance heart health and lower blood sugar levels in individuals with type 2 diabetes. Further research is still needed to investigate these and other promising health benefits of these seeds (1).

How Much Kalonji Should I Take For Weight Loss?

When preparing kalonji water, you only need to use at least 5 to 10 nigella seeds. Instead of using them as they are, you crush them to make a fine powder before adding them to a glass of warm water. 

Make sure you mix well before consuming. Alternatively, you can add a spoon of honey and the juice of half a lemon for added benefits.
