Improvement in the high-fat diet-induced dyslipidemia and adiponectin levels by fish oil feeding combined with food restriction in obese KKAy mice.

The effect on weight reduction of fish oil combined with food restriction in comparison with that of beef tallow was investigated in high-fat diet-induced obese KKAy mice. Although the reduction of body and white adipose tissue weight was similar in the two groups, fish oil increased adiponectin levels in the plasma, improved dyslipidemia accompanied by suppression of lipid synthesis in the liver when compared with beef tallow.
