Fish oil may or may not help you with weight management, or more specifically, fat management. Several factors come into play, some of which can enhance the positive effects of fish oil and others of which can undermine them. Read more… »

Fish oil weight loss benefits include protection against metabolic syndrome. DHA deficiency, on the other hand is linked to obesity, metabolic syndrome, and even MS. Read this summary of a research article by scientists at Louis Pasteur University in Strasbourg, France.

DHA deficiency linked to obesity

STRASBOURG, FRANCE. Obesity is a growing problem among adolescents and is often accompanied by metabolic syndrome (MS). Metabolic syndrome involves a cluster of several metabolic abnormalities including overweight (specifically abdominal adiposity), insulin resistance, high triglycerides and low HDL (high-density lipoprotein) levels, and is associated with an increased risk of cardiovascular disease.

Researchers at the Louis Pasteur University of Strasbourg now report that overweight adolescents and overweight adolescents with MS exhibit significant differences in the fatty acid content of plasma phospholipids when compared to their non-overweight peers. Their study involved 60 12-year-olds (30 boys and 30 girls) with normal weight and 60 12-year-olds who were overweight. Twenty-five per cent of the overweight children had been diagnosed with MS as well (none of the normal weight children had MS). Analyses of the phospholipid phase of the blood plasma revealed several important differences between the overweight and normal-weight groups. There was a highly significant difference in DHA (docosahexaenoic acid) concentration with normal-weight subjects having a substantially higher level. Normal-weight participants also had a significantly higher ratio of polyunsaturated fatty acids (PUFAs) to standard fatty acid (SFAs). Furthermore, overweight adolescents with MS had even lower levels of DHA and lower PUFA/SFA ratios than did those who were merely overweight.

The researchers conclude that a diet providing a high ratio of PUFAs to SFAs and, more specifically, a high intake of long-chain PUFAs such as DHA may protect obese persons against the development of metabolic syndrome.

Key Fish Oil Component

By all accounts from recent research, the key omega-3 oil from fish is DHA. (The other main omega-3 from fish oil is EPA.) Weight control and other benefits regarding metabolism are just one of the many important benefits from fish oil.

All the best for fish oil weight loss,
