The aim of this study was to assess the effectiveness of a long-term interdisciplinary lifestyle modification therapy on food intake, body composition, and anthropometric measurements of obese women. ⋯ Long-term interdisciplinary therapy was effective in decreasing the intake of calories, carbohydrates, and fats. The therapy positively changed the body composition and reduced anthropometric measurements. However, the intake of some micronutrients after therapy was still significantly lower than recommended. These results demonstrated that the proposed interdisciplinary methodology can be effective in treating obesity; however, the present study reinforced the need to address the micronutrient deficiency in the target population.

One of every four pregnant women in Chile is obese. Gestational obesity is associated with maternal metabolic complications in pregnancy (e.g., gestational diabetes, preeclampsia), but to our knowledge, there is little evidence on relationships with future metabolic risk. The aim of this study was to evaluate the association between prepregnancy obesity (prepregnancy body mass index ≥30 kg/m(2)) or excessive gestational weight gain (GWG; according to the 2009 recommendations from the Institute of Medicine), and maternal metabolic complications 10 y postpartum in premenopausal Chilean women. ⋯ Gestational obesity was associated with maternal metabolic alterations 10 y postpartum. Prevention strategies for chronic diseases should consider prepregnancy obesity as a modifiable risk factor for future metabolic health.

The aim of this study was to assess whether diet quality and functional status were associated with serum levels of interleukin (IL)-6 and tumor necrosis factor (TNF)-α in frail, elderly, community-dwelling individuals. ⋯ MAR of the diet was inversely associated with IL-6 concentration in frail elderly individuals, and higher SPPB score was associated with lower levels of TNF-α. Results from the present study suggest that improving diet quality and physical performance might lower levels of inflammation in this frail, elderly population.

A citrulline (CIT)-enriched diet improves locomotor activity in aged rats, but the underlying mechanism is unknown. The aim of this study was to determine the effect of CIT administration on locomotor activity and dopamine activity in healthy aged rats. ⋯ In aged rats, CIT is able to stimulate locomotor activity via the dopaminergic pathway.

The "lipid hypothesis" determined that saturated fatty acid (SFA) raises low-density lipoprotein cholesterol, thereby increasing the risk for metabolic syndrome (MetS). The aim of this study was to investigate the effect of subchronic withdrawal from a high-carbohydrate, high-saturated fat (HCHF) diet during MetS with reference to changes in deleterious SFA (C12:0, lauric acid; C14:0, myristic acid; C16:0, palmitic acid; C18:0, stearic acid) distribution in liver, white adipose tissue (WAT), and feces. ⋯ The prolonged consumption of an HCHF diet leads to increased SFA accumulation in liver and WAT, decreased SFA excretion, and reduced hepatic LDLr expression during MetS, which is prominently reversed after subchronic withdrawal of the HCHF diet. This can contribute to better understanding of the metabolic fate of dietary SFA during MetS and may apply to the potential reversal of complications by the simple approach of nutritional modification.
