how does a hight fat diet decrease lipogenesis

Br J Nutr — Received Jun 24; Revised Sep In principal, mass enrichment of 13 C or 2 H tracers can be detected in any newly synthesized lipid using MS and chromatographic separation Recent research has established that sterol regulatory element binding protein-1 is a critical intermediate in the pro- or anti-lipogenic action of several hormones and nutrients. We found that total carbohydrate and alcohol intake were associated with lower and higher estimated SCD activity, respectively. Nutrition 30, 1—9. Cettour-Rose, P. D and J. Peroxidase-catalyzed color development from o-Phenylenediamine was measured at nm. Satapati S.

In white adipose tissue of these mice, expression of genes implicated in cholesterol metabolism was markedly elevated, whereas the expression of genes implicated in fatty acid and triglyceride synthesis remained unchanged Shimomura et al. Nutrition 30, 1—9. Obesity: overview of prevalence, etiology, and treatment. Body protein was determined from a general formula relating energy derived from fat, total energy value of the carcass, and energy derived from protein Dulloo and Girardier, ; the caloric values for body fat and protein were taken as In equation 17, and subsequent equations, the proton spectrum is used to normalize the deuterium spectrum i. Desaturase activity was determined in a similar fashion as lipogenic flux. Journal List J Lipid Res v. Penicaud, L. Thus, reduction of the C:L ratio from 3. Cettour-Rose, P. For weight gain and adiposity, the differences between groups could be due to several mechanisms that are interdependent.

Solinas, G. CrossRef Full Text. When deuterated water is administered, deuterium enriches these positions proportional to the synthesis rate, which 2 H NMR detects as stoichiometric peak intensities in the various functional groups of the lipid molecule. The non-linear relationship between these two latter biomarkers and disaccharide intake, however, warrant further study of both n-7 and SCD-1 index in PL as potential biomarkers of very high sugar intake. No significant variation was found in the activity levels of the two groups of rats Table 3. Cell size distributions in the retroperitoneal fat pad were similar to those of the subcutaneous WAT Fig. Metabolism 41, — Notably, SFA intake was weakly but significantly directly associated with adipose tissue and , suggesting that in Swedish male populations around the time of the s, higher proportions of SFA and in serum and AT do not seem to reflect a higher carbohydrate intake and DNL activity, but more probably a higher dietary SFA and alcohol intake. Fasting reduces lipogenesis in adipose tissue, which, combined with an increased rate of lipolysis, leads to net loss of triglycerides from fat cells.
