This article reviews the present evidence on whether omega-3s fish oil can assist you to lose weight. Fish oil is one among the foremost common supplements on the market. It’s rich in omega-3 fatty acids. These omega-3 fatty acids supply various health benefits. Such as better heart and brain health, reduced risk of depression and even better skin health.
What Are Fish Oil Omega-3?
Omega-3 fatty acids are a family of fats that’s essential for human health. There are several sorts of omega-3 fats, but the foremost important ones are often categorized into two main groups:
Essential omega-3 carboxylic acids: omega-3 fatty acid (ALA) is the only essential omega-3 fatty acid. It is found during a wide selection of plant foods. Walnuts, hemp seeds, chia seeds, flaxseeds, and their oils are the richest sources.
Long-chain omega-3 fatty acids: the 2 most known are omega-3 fatty acid (EPA) and omega-3 fatty acid (DHA). They are mainly found in fish oil and fatty fish, and also in seafood, algae and algae oil.
ALA is taken into account essential because your body can’t produce it. This means you want to get this sort of fat from your diet.
On the opposite hand, EPA and DHA aren’t technically considered essential. Because the physical body can use ALA to supply them.
However, this conversion isn’t very efficient in humans. Your body turns only about 2–10% of the ALA you consume into EPA and DHA.
EPA and DHA are involved in many essential body functions, like a brain and eye development and performance.
Studies show that maintaining adequate levels of EPA and DHA can also help prevent inflammation, depression, and carcinoma.
There are many fish oil omega-3 supplements on the market, usually available as oil drops or capsules.
Fish Oil May Reduce Hunger and Appetite
Fish oil omega-3s may help people reduce in several ways, the primary of which involves reducing hunger and appetite.
This effect could also be particularly useful for those that are following weight-loss diets. Because dieting may sometimes cause increased feelings of hunger.
In one study, healthy people on a weight loss diet consumed either fewer than 0.3 grams or quite 1.3 grams of fish oil omega-3s per day. The high-fish-oil group reported feeling significantly fuller up to 2 hours after a meal
However, these effects are not universal.
Interestingly, one study observed that fish oil omega-3s increased the amount of a fullness hormone in obese people, but decreased levels of an equivalent hormone in non-obese people.
Thus, it’s possible that effects vary counting on your health status and diet. However, more studies are needed before strong conclusions are often made.
Fish Oil May Increase Metabolism
Another way fish oil omega-3s may assist you to reduce is by increasing your metabolism.
Your metabolism is often measured by your rate, which determines the number of calories you burn every day.
The higher your rate, the more calories you burn and therefore the easier it’s to reduce and keep it off.
One small study reported that when healthy young adults took 6 grams of fish oil per day for 12 weeks, their metabolic rates increased by around 3.8%.
In another study, when healthy older women took 3 grams of fish oil per day for 12 weeks, their metabolic rates increased by around 14%, which is that the equivalent of burning an extra 187 calories per day
Most of the studies reporting increases in metabolic rates also observed a rise in muscle mass. Muscle burns more calories than fat, thus a rise in muscle mass may explain the upper metabolic rates observed in these studies.
That said, not all studies have observed this effect. Thus, more studies are needed to know the precise effects of fish oil on metabolic rates.
Fish Oil May Boost the Effects of Exercise
Research suggests that consuming fish oil can also amplify the number of calories you burn during exercise.
Researchers believe this happens because fish oil may assist you to switch from using carbohydrates to fat as a source of fuel during exercise.
One study reports that ladies given 3 grams of fish oil per day for 12 weeks burned 10% more calories and 19–27% more fat once they exercised.
Fish Oil May assist you Lose Fat
Even if fish oil omega-3s don’t help some people reduce, they’ll still help them build muscle and lose body fat.
People that want to reduce are often encouraged to use a tape or track their body fat percentages to assess their progress, instead of relying only on the size.
Using bodyweight to trace the loss of body fat can also explain why some studies have did not find any effect of fish oil omega-3s on weight loss. However, studies that use more precise measurements of fat loss often tell another story.
For instance, a study of 44 people reported that those given 4 grams of fish oil per day did not tend to lose weight more than those given a placebo.
In another study, six healthy adults replaced 6 grams of fat in their diets with 6 grams of fish oil every day for Fish oil does reduce waist circumference and waist-to-hip ratio more effectively.
Thus, fish oil might not assist you to reduce intrinsically, but it’s going to make it easier for you to lose inches and assist you to go down in clothing sizes.
Dosage and Safety
Among the foremost recent studies that found that fish oil had a positive effect on weight or fat loss, daily dosages of 300–3,000 mg were used.
It’s good to stay in mind that omega-3s have blood-thinning effects which will cause excessive bleeding in some people.
If you’re taking blood-thinning medication, ask a healthcare professional before adding fish oil supplements to your diet.
In addition, take care of the sort of fish oil supplements you’re taking. Some may contain vitamin A, which may be toxic when taken in high amounts, especially in pregnant women and young children. Cod liver oil is one example.
And finally, confirm you concentrate on the content of your fish oil supplements.
Unfortunately, certain types actually don’t contain much fish oil, EPA or DHA. To avoid these “fake” products, pick a supplement that has been tested by a 3rd party
