Benefits Of Lemongrass For Weight Loss

What is lemongrass?

Lemongrass is a tropical herb that comes from the lemongrass plant and is native to many Asian countries, such as India, Sri Lanka, Thailand, etc. but is now grown in other parts of the world too. The lower portion of the lemongrass plant (stalk) is used in various Asian cuisines; the leaf is used in herbal tea, salads, and soups; and the lemongrass essential oil is a great stress buster, helping to combat anxiety and depression when used in aromatherapy.

Lemongrass has a stingy, citrus flavour (different to sourness) and has many health benefits, including having an effect on weight loss, which will be discussed further in this article. 

Benefits of lemongrass for weight loss

The term ‘weight loss’ is used everywhere. In a 2018 July report from the CDC,1 data from the National Health and Nutrition Examination Survey shows that in the year 2013–2016, 49.1% of U.S. adults tried to lose weight in the last 12 months, including 56.4% of women and 41.7% of men tried to lose weight.

Lemongrass contains polyphenolic compounds2 such as flavonoids, tannins, etc., and citral, which is also responsible for its lemon aroma and flavour. Drinking lemongrass tea every day can help in increasing your metabolic rate. Polyphenolic compounds, especially flavonoids and phenolic acids, inhibit α-glucosidase and α-amylase, which are the key enzymes responsible for the digestion of dietary carbohydrates to glucose. Phenolic compounds available in beverages, vegetables, galenical pears, and berries, may facilitate fitness thereby decreasing the risk of metabolic syndrome.3

We often hear about the term ‘metabolism’ concerning weight loss. Metabolism is the chemical change4 that takes place in a cell or an organism, building energy and keeping the organism moving. Metabolism helps eliminate toxic substances from the body, the higher the metabolism, the higher the calorie count of an individual to maintain body weight.5
