Fish oil is the best option for healthy weight loss. This healthy fat found in fatty fish is the richest natural source of omega-3 fatty acids. Researchers have found that fish oil can help improve cardiovascular health, promote brain development, and reduce inflammation and the risk of diabetes. In fact, fish oil also reduces cortisol levels and can help you get rid of belly fat! In this article, we will discuss how using fish oil for weight loss is beneficial, supplements, dosage, whether you should consume it during pregnancy, and much more. But first, let me tell you about fish oil in brief.

What Is Fish Oil?

Fish oil is derived from fatty fish. It is loaded with Polyunsaturated Fatty Acids (PUFAs), known as omega-3 and omega-6 fatty acids. They are called PUFAs because they have multiple double bonds in their chemical structure. These have been found to be beneficial for human health as compared to saturated fatty acids (no double bond in the chemical structure).

Now, let’s dig a little deep. There are three types of omega-3 fatty acids – EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and alpha-linolenic acid (ALA). And these are important for better human health. ALA can be synthesized by humans but not EPA and DHA. Though ALA can be converted into EPA and DHA, the conversion percent is very low. Fortunately, fish oil or fatty fish is the only source from which you can get the recommended ratio of EPA-DHA, which is 1.5:1. How does this ratio or, in general, omega-3 fatty acid in fish oil aids weight loss? Let’s find out in the next section.

Bottom Line: Fish oil from fatty fish is a great source of omega-3 fatty acids (EPA and DHA) that are beneficial for human health.

How Fish Oil Aids Weight Loss

Weight loss is determined by a number of factors, but most of us suffer from a common problem – not being able to get enough omega-3 fatty acids from regular food sources. And this is one of the major reasons for weight gain.

In general, the ratio of omega-6 fatty acids to omega-3 fatty acids should be 1:1. But, according to a study published in Biomedicine & Pharmacotherapy, this ratio is 15:1 or higher in Western diets. This imbalance results in cardiovascular diseases, inflammation, stress, depression, obesity, and cancer.

By consuming fatty fish or taking fish oil supplements, you can restore the omega-6 and omega-3 ratio. This, in turn, reduces inflammation and inflammation-induced weight gain and improves lipid profile. This is the basic scientific logic behind fish oil’s magical weight loss properties.

Here are some more cool facts and research studies that connect the dots between fish oil and weight loss.

  • Fish Oil Increases Satiety

 In an experiment, obese patients were supplemented with long-chain omega-3 fatty acids along with diet restrictions. The patients were provided with 260 mg/day or 1300 mg/per day of omega-3 fatty acids, and their postprandial satiety was measured.

Patients supplemented with both doses of omega-3 fatty acids reported higher satiety levels. Therefore, it can be concluded that consuming fatty fish or fish oil supplements can help suppress your appetite. This, in turn, will prevent you from overeating and gaining weight.

  • Fish Oil Lowers Triglyceride Levels

Triglycerides are the end products of fat digestion in your body. They circulate in the blood and are used by the body as energy or are taken up by the fat cells and stored.

When you consume a lot of unhealthy food and don’t work out, the triglyceride levels go up. This puts you at the risk of obesity and related diseases like heart disease, diabetes, atherosclerosis, etc.

It has been found that the omega-3 fatty acids in fish oil help lower the serum triglyceride levels. Triglycerides are synthesized by joining the fatty acid molecules. Omega-3 fatty acids reduce the availability and delivery of fatty acids and decrease the fatty acid synthesizing enzymes. This, in turn, prevents the formation of triglyceride molecules and protects you from gaining weight (visceral and subcutaneous fat).

  • Fish Oil Helps Burn The Fat

Fat oxidation is the process where fat molecules are broken down into fatty acids and triglycerides. This process is necessary for the cells to be able to function properly because fat, as such, cannot be directly used as an energy source. But, as mentioned before, too many triglycerides in the blood can be very harmful.

Sadly, most obese and sedentary people have high triglyceride levels in the blood. And this is the where fish oil comes into the picture. Researchers from France conducted an experiment with a few healthy individuals. For three weeks, the participants were on a controlled diet, and for the next 10-12 weeks, they were given 6g/day of fish oil along with the same controlled diet. After 12 weeks, the results were recorded, and it was found that the fish oil induced fat oxidation. Therefore, fish oil can help you mobilize the fat and help you lose the extra fat.

  • Fish Oil Lowers LDL Cholesterol

LDL cholesterol is also known as bad cholesterol. And that’s because an increase in the LDL cholesterol levels can lead to clogged arteries. Unfortunately, obese people have a higher level of LDL cholesterol and lower levels of HDL or good cholesterol in their blood. In a study, researchers reported that human participants supplemented with fish oil had decreased LDL cholesterol levels. In another study by American scientists, omega-3 fatty acids helped increase the HDL or good cholesterol levels. Therefore, if you are obese and need to lose weight, add fish oil to your diet. It will not only help you lose subcutaneous fat but also reduce the risk of obesity-related diseases.

  • Fish Oil Helps Build Muscle

Fish oil also helps build muscle, which helps to increase the metabolic rate. Scientists have found that supplementing human participants with fish oil aided muscle anabolism and improved muscle mass.

  • Fish OIl Prevents Insulin Resistance

Your body can become insulin resistant when your blood sugar levels are constantly high. Insulin becomes insensitive to glucose and doesn’t take it up. This makes you feel hungry as your cells are devoid of glucose. As a result, you eat more and gain weight. Researchers have found that fish oil helped increase insulin sensitivity in human participants with metabolic disorders.

  • Fish Oil Reduces Inflammation

Inflammation is the first sign of wound healing. But it is not good when it continues for a long period. It not only induces physical discomfort but can also weaken your immunity. Moreover, prolonged periods of stress in the body can also make you gain weight. Studies have confirmed that fish oil is anti-inflammatory. It helps reduce the inflammation in the body by inhibiting the inflammatory pathways.

 So, these were the scientific reasons behind fish oil’s weight loss aiding property. Now, let’s talk about how much fish oil should you take for weight loss.

Fish Oil Dosage For Weight Loss

You can either consume fatty fish or use fish oil pills or supplements. Here is how much fish oil you should take for weight loss.

  • Healthy individuals – 500 mg/day
  • Obese individuals – 800-1000 mg/day

Remember, the dosage will vary depending on your age, medical history, current medications, etc. So, talk to your doctor before taking fish oil to determine the correct dosage for you.
