Four Ways Fish Oil Can Help You Lose Weight

Are you wondering how fish can oil help you lose weight?

Fish oils are an excellent source the omega 3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

A number of multiple study reviews have shown that these long chain polyunsaturated omega 3 fatty acids are beneficial for reducing obesity.

The research shows that fish oils can help weight loss by:

  • suppressing the appetite and enhancing fat burning
  • reducing the body’s ability to store fat
  • boosting protein metabolism which fosters muscle growth 
  • improving insulin sensitivity in overweight individuals

This article takes a closer look at the effects of EPA, DHA and fish oil in obesity and weight loss. 


1.  Omega 3 Fatty Acids Protect Against Obesity

A study published in the 2009 issue of Obesity Reviews reported that an increased intake of EPA and DHA helps reduce body fat due to their appetite-suppressing effects.

It was also found that omega 3 fatty acids can curb fat deposition and increase energy expenditure due to altering the DNA in skeletal muscle.


2. Fish Oils Improve Insulin Sensitivity in Overweight Individuals

It turns out that fish oils can help you lose weight by increasing your sensitivity to insulin.

What does insulin have to do with helping you lose weight??

Insulin is the main hormone responsible for converting your blood glucose into energy. It also plays an important role influencing an enzyme that helps your body break down extra fat stores.

Researchers have proven that overweight and obese people are more insensitive to insulin. Therefore, people who are less sensitive to insulin have a greater likelihood of storing fat and will have more difficulty losing weight.

A study in The Journal of Diabetes Research showed that taking 3 grams a day of EPA and DHA caused increased insulin sensitivity and lower triglyceride levels.

Scientists concluded that this increased insulin sensitivity may help the body break down body fat more efficiently which could promote more effective weight loss.


2.  Fish Oil Helps Weight Loss by Enhancing Protein Metabolism

Your muscles are some of the most metabolic-active tissues in the body.

Scientists believe that overweight people who increase their muscle mass can boost their metabolisms which provides a stronger calorie-burning effect.

An interesting study looking at cancer-induced weight loss showed that fish oils helped reduced protein breakdown through enhanced protein metabolism.

It’s thought that improving your body’s ability to metabolize protein may encourage more muscle growth; and having more overall muscle boosts your metabolism by burning more calories. 

The researchers found that a minimum daily dose of 1.5 grams of fish oils was associated with improvements.


3.  Adding Seafood or Fish Oil to Diet Improves Weight Loss

Turns out that just adding seafood to your diet may help you lose even more weight….

Icelandic researchers found that adding fish oil to your diet can boost weight loss efforts. Study participants eating a low-calorie diet who included either fatty fish or fish oils, lost about 2 pounds more than people who didn’t include seafood or fish oils in their diet.


4.  Fish Oils Help Your Body Stop Storing Fat

When you eat food, your body converts it into glucose which is used for energy. Any excess glucose not used up for energy is stored as body fat.

Scientists in the Czech Republic discovered fish oils help weight loss in overweight women due to a reduced conversion of glucose to fat.

Researchers stated that fish oil may help weight loss efforts by reducing the body’s tendency to store excess calories as body fat.


What’s the Best Fish Oil Dosage to Lose Weight?

The current research shows that fish oils and omega 3 fatty acids may play a role in enhancing weight loss.

Due to the variety of guidelines seen in many weight loss studies, more research is needed to determine the best fish oil dosage that will help weight loss.

For example, a study in Australia found 6 grams a day of fish oil that provided 1.9 grams of omega 3 fatty acids helped people lose weight and reduced their triglyceride levels.

Another study published in the Journal of International Society of Sports Nutrition showed 4 grams a day of fish oil providing 1600 mg of EPA and 800 mg of DHA help lower body fat and increase muscle mass.

Furthermore, some food scientists believe that the fat-burning effect of fish oils may only be seen in obese or sedentary individuals who aren’t participating in any regular exercise plan.

It’s recommended you consult with your physician to help you plan a safe and appropriate weight loss plan that meets your individual health needs.
