title: Adipose tissue lipoprotein lipase activity in rats maintained at a reduced body weight.
abstract: Male rats fed a cellulose-diluted diet maintained a reduced body weight. Adipose tissue lipoprotein lipase (LPL) activity decreased after two days of cellulose feeding, but was not different from chow-fed control levels with weight stabilized at 90% or 70% of the control group. Plasma triglyceride concentration decreased with weight loss and remained depressed with stabilized reduced weight. Regaining lost weight had no effect on LPL activity when compared with chow-fed controls or with levels obtained for the weight-reduced group. However, plasma triglyceride concentration returned to chow-fed control levels with weight gain. The disparity between these results and those obtained in obese human beings lends support to the hypothesis that the increase in adipose tissue LPL activity in weight-reduced obese human beings is indicative of a defect in regulation of adipose tissue metabolism.
