OMEGA 3 AND WEIGHT LOSS



Fish oil supplements may help overweight people and people with high blood pressure to lose weight, according to the National Institutes of Health. Omega-3 fatty acids or polyunsaturated fatty acids, are found in fish oil. They are considered essential to your diet because your body can't make them. Take supplements only under the care of a knowledgeable health care provider to prevent adverse side effects and interactions with other medications you may be taking.

Identification

Omega-3 fatty acids are integral to brain function and normal growth and development. They may reduce risk of heart disease. Docosahexaenoic acid, or DHA, and eicosapentaenoic acid, or EPA, are types of omega-3 fatty acids found in fish oil. Alpha-linolenic acid or ALA, is a kind of omega-3 fatty acid found in some nuts, like English walnuts and vegetable oils, including canola, soybean, flaxseed/linseed and olive oil. The American Heart Association recommends getting omega-3 fatty acids from fatty fish twice per week.

Effects

Rats fed fish oil gained less weight and fat than those fed soybean oil, according to a 2002 study published by Michael Pellizzon in "Obesity Research." A diet rich in omega-3 fatty acids may protect against obesity, according to a 2000 study published by Hongqin Wang and colleagues in the "American Journal of Physiology, Endocrinology and Metabolism." A group of rats fed a diet with high omega-3 fatty acids had reduced fat and leptin levels. Leptin is a hormone that has an effect on appetite regulation. Leptin concentrations are low in people and animals with low body fat.

Mechanism

 

EPA and DHA may reduce accumulation of body fat by limiting both hypertrophy and hyperplasia of fat cells, according to a 2004 study in "Lipids." Hypertrophy refers to an increase in bulk. Hyperplasia means increased cell production. Researcher Jana Ruzickova and colleagues also proposed that increased intake of EPA and DHA may be beneficial regardless of ALA intake.

Fish Oil Supplements and Weight Loss

Fish oil supplements that contain DHA prevent pre-fat cells from becoming fat cells by killing them. As a result, they help in weight loss by decreasing the accumulation of fat in the body. In addition, they reprogram the genes so that carbohydrates are broken down by the body and not stored as fat. The Omega-3 fatty acids in fish oil supplements increase your rate of metabolism and blood flow, which in turn assists in weight loss. These supplements should be taken in conjunction with a high protein balanced diet, a healthy lifestyle and regular exercise. Studies Carried Out

There have been several studies carried out to show the connection between fish oil supplements and weight loss. In one study, four groups were monitored. One group was given fish oil supplements, and the second was given fish oil supplements but had to exercise regularly. A third group was only given sunflower oil, and the last group was given sunflower oil and they too were made to exercise regularly. It was found that only the group that was given fish oil supplements and made to exercise regularly experienced weight loss. Hence, fish oil supplements can’t make you lose weight unless you consume plenty of water, exercise regularly and adhere to a healthy and nutritious diet.

Other Benefits of Fish Oil Supplements

The Omega-3 fatty acids in fish oil supplements are important for the growth and development of the body and for proper brain function. Fish oil is especially beneficial to patients suffering from Alzheimer’s disease or strokes. The supplements also benefit people suffering from diabetes, arthritis, cancer, heart disease and inflammation. These supplements boost the immune system and make you better able to fight and recover from diseases. Fish oil supplements are available in capsule form and can be easily obtained at most medical stores. Besides assisting you in losing weight, these supplements help you live a healthier life.
