Drinking Fennel Seed Water for Weight Loss

I love researching and writing about the health benefits of various fruits and vegetables.

What Is Fennel Seed Water?

Fennel seed water is simply water infused with fennel seeds. Infusing can be done either by immersing the seeds in hot water or by steeping them overnight in cool water. The infused water has a light golden colour, smells fresh and clean, and the taste is not bad at all! In the beginning, I did find the taste weird but I got used to it quickly!

In this article, you will learn how to make a large batch of fennel seed water so that you can sip it throughout the day. I found out about this kind of water a couple of months ago, but I only decided to write about it after I tested it out myself. It's a time-tested, ancient herbal remedy that is prescribed in Ayurvedic medicine as a treatment for obesity.

These seeds are tiny powerhouses of detoxifying and metabolism-boosting nutrients. They are rich in vitamins as well as minerals, as shown in the nutrition facts table later in the article.

How Fennel Water Helps You Lose Weight

  1. It increases metabolism. Metabolism refers to the rate at which our cells use up energy from the food we eat. By boosting metabolism, calories in food are burned off faster in the body, aiding in fat loss.
  2. It is a natural appetite suppressant. Thinking of purchasing artificial appetite suppressing tablets? Drink fennel water instead. Even chewing on the seeds helps naturally quell appetite.
  3. The seeds are said to aid in blood purification. Fennel seed water may help clear out excess uric acid in the blood stream and break down bile. It promotes digestion of fats in the liver as well.
  4. The water may help to detoxify the body. In today's world, we are bombarded with toxins from every angle, from car exhaust fumes to cosmetic products. This drink helps flush out the toxins in the blood stream via the kidneys.
  5. It is a mild stimulant. This infused water can help you keep alert and awake, without caffeine! Sipping the water throughout the day can help you keep alert and awake, giving you just enough motivation to get up and exercise, without the usual caffeine crash.
  6. An anti-spasmodic effect. The anti-spasmodic effect of fennel helps suppress hunger pangs by relaxing the stomach muscles that produce the sensation. This can help you intake less calories and lose excess weight.
  7. It may stimulate melatonin. Melatonin is a natural hormone produced in the brain by the pituitary gland, which is responsible for regulating sleep. A good night's sleep of 6-8 hours is crucial for healthy weight loss and maintenance.
Benefits of drinking fennel seed water include increased metabolism, appetite suppressant, and mild diuretic.

Uses in Traditional Medicine

Fennel seeds have been used by people since antiquity for a wide range of ailments, including respiratory, digestive, and even reproductive disorders. For an excellent overview of the health benefits, read this study conducted at the National Institute for Research in Reproductive Health in Mumbai, India.

Some women use fennel to increase the flow of breast milk.

Fennel Water Recipes for Weight Loss

Making fennel water is a simple task that doesn't require any complicated procedures.

Let's get right into the recipe. In my experience, there are two types of preparation:

  1. Brewing the seeds in boiling water and allowing them to cool.
  2. Overnight steeping.

How to Make Fennel Seed Water (Hot Brew Method)

Here is my first recipe for fennel seed water, made by brewing the seeds in hot water.


  • 1 liter or quart distilled water
  • 2 tablespoons raw fennel seeds


  1. In a deep pan, bring the quart of water to a boil. You can boil the water in your kettle, too, and transfer it to a pot.
  2. When the water starts bubbling, toss in the fennel seeds and immediately switch off the heat.
  3. Cover the pot with a lid and allow tea to cool to room temperature.
  4. Once it cools, your fennel water is ready! All you have to do is to transfer it into your glass jar or bottle and drink throughout the day.
  5. If you want to make a larger batch, simply double the recipe. Store in the fridge if you don't have time to make a fresh batch everyday.


  • If possible, use distilled water.
  • For extra aroma, roast the fennel seeds in a pan until they give off a sweet, toasted scent (about 20 seconds of toasting on a heated pan is needed).
  • For beginners, consider starting out with a smaller dose of seeds by using half the amount in the recipe. Work your way up as you get used to it.

Fennel boosts the metabolism, which will help you to burn fat more quickly.

How to Make Fennel Water (Overnight Brewing Method)

Lately I have preferred this method. It nice to have the water ready in the morning, when I'm in a rush to head out the door. Also, it doesn't involve applying heat, so the nutrients in the seeds are not destroyed. This method also requires fewer utensils so I have less washing up to do!

  1. Get a glass jar, add in 2 tablespoons of raw fennel seeds and fill with 1 quart or liter of distilled water.
  2. Cover with a lid or screwtop.
  3. At first the seeds will float on the top, but by morning they will be engorged with water and will have sunk to the bottom.

How Much Should I Drink?

As with all things, drinking fennel water should be done in moderation.

  • Follow the recipe given and make one batch of 1 litre or 4 cups per day. Sip throughout the day. Take your weight loss on a day-by-day basis.
  • If you are worried about any adverse symptoms, begin with one cup of fennel water per day and see how you react to it. You can the build up to 4 cups per day gradually.
  • Always consult your health care practitioner.
Fennel increases metabolism, which means you will burn more calories and fat.

6. Relieves Menstrual Problems

Many factors, including stress and poor diet, can interrupt a woman’s regular menstrual cycle. Fennel seeds have emmenagogue properties that promote and regulate menstrual flow. The herb also has phytoestrogens that help with issues like premenstrual syndrome, menopausal disorders, and breast enlargement.

A 2012 study conducted by researchers from Babol University of Medical Sciences and Health Services in Iran also indicates that fennel can help reduce symptoms of dysmenorrheal or painful menstruation.

Apart from menstrual benefits, fennel is traditionally used as a galactagogue to promote lactation in nursing mothers. It also works as an aphrodisiac to increase libido in both men and women.

gobi. on January 15, 2015:

Thanx for this remedies..its really works..

Abraham on January 14, 2015:

Wow, I am grateful for this hub: This reaffirms why I started drinking this and fenugreek tea/water in the morning to detox for better health (I am fascinated with herbal medicine from all cultures!). I definitely feel more energized and leaner when fenugreek and fennel seeds are in my diet.

Also, although I completely agree that everyone should do their own research and make educated/informed decisions when starting a new "diet", did you know that after pregnancy fennel and fenugreek is good for you? Apparently it increases lactation/milk production and balances hormones out!

aditi on January 11, 2015:

In this method, all you have to do is to get a glass jar, pour in 2 tablespoons of fennel water and fill it up with 1 litre of water

Hello, preweb! I believe fennel infused tea or fennel water is the remedy for weight loss in particular. Water has zero calories and fills your stomach and the fennel in fennel water has many properties that help suppress appetite.

As for your second question, is it possible to overdose on fennel seeds? The answer is, too much of anything can be bad for you. Eating a teaspoon of fennel seeds after every meal, for breath freshening is quite enough. You wouldn't need to eat fennel seeds more often than this.

Hope you found this helpful!

preweb from UK on April 25, 2014:

Nice hub. I always eat fennel seeds as a mouth fresher but didn't know other benefits earlier. One of my friend keeps chewing fennel seeds all day. Does over eating has any side effects? And is eating fennel seed has the same benefits as

fennel water ?
