In five experiments where guar gum (GG) or Solka-floc cellulose (SF) supplemented a semi-synthetic diet (100 g/kg) for male Wistar rats at 21°, it was found that GG acutely depressed both ad lib. and meal-fed food intakes by 40–50 %. The effect was temporary, with the GG having no effects on food intake in the longer term. Dietary energy balance over 28 d with animals fed on equal amounts of a basal ration showed partial digestible energy values, calculated from the intake and faecal loss of energy, for the supplements which averaged 0 kJ/g SF and 10 kJ/g GG, so that GG contributed substantial amounts of absorbable energy. Despite this additional energy from GG, there was very often no additional gain of body fat. Rather, in some experiments, fat deposition was actually decreased by supplementation with GG. GG is inferred to have a putative thermogenic effect which is often greater than the energy it supplies. This effect occurred to a greater extent in circumstances associated with a higher ‘energy status’, indicated by higher efficiencies of conversion of gross dietary energy to retained body energy, higher fat: lean tissue deposition ratios and the occurrence of larger deposits at the epididymal fat pad site. There was some evidence that deposition at this site was more extensively affected by GG than deposition of fat in the body as a whole. Possible implications of the present findings are discussed.

Hace falta evidencia acerca de la sinergia entre los factores psicológicos y contextuales que subyacen a la práctica simultánea de las conductas del balance energético corporal [BEC] (actividad física [AF], alimentación saludable [AS] y sueño de calidad [SC]). Por ello, se busca identificar si el optimismo disposicional [OD], flexibilidad en regulación emocional [RE], las creencias compensatorias en salud [CCS] y factores ambientales – socioculturales, predicen los dominios conductuales señalados en adultos, a través de un Modelo de Ecuaciones Estructurales [MEE]. Para ello, se dispuso de una investigación explicativa trasversal con una muestra de 300 participantes, que diligenciaron un cuadernillo compuesto por instrumentos psicométricos validados (uno por cada variable indagada). Los resultados establecieron que la tendencia a la realización de las conductas el BEC es predicha por los factores contextuales referidos y las variables psicológicas evaluadas (R=.54, valor p < .05). Se valida un modelo hipotético que incorpora el agregado conductual del sueño en la ecuación del BEC, susceptible de modificación e inclusión de nuevas variables.  Abstract. There is a lack of evidence about the synergy between the psychological and contextual factors that underlie the simultaneous practice of the behavioral domains of the Body Energy Balance [BEB] (Physical Activity [PA], Healthy Eating [HE] & Quality Sleep [QS]). Therefore, we seek to identify whether dispositional optimism [DO], emotion regulation [ER] flexibility, compensatory health beliefs [CHB], and environmental-sociocultural factors, predict behaviors of the body energy balance [BEB] in adults, through a Structural Equation Model [SEM]. To do this, cross-sectional explanatory research was available with a sample of 300 participants, who completed a booklet made up of validated psychometric instruments (one for each variable investigated). The results established that the tendency to perform the BEB behaviors is predicted by the contextual factors referred to, and the psychological variables were evaluated (R=.54, p-value < .05). A hypothetical model that incorporates the behavioral aggregate of sleep in the BEB equation is validated, subject to modification and inclusion of new variables.

There is no document that analyzes the state of the art of scientific research published between 2013 and 2018 in relation to possible interdependence links between emotional regulation [ER] and healthy behaviors associated with Body Energy Balance [BEB] (physical activity, balanced diet and sleep hygiene). To achieve this purpose, an exploratory systematic review was conducted, whose search criteria were “emotion regulation”, “emotion dysregulation” connected with the Boolean operator “AND” to the keywords “sleep hygiene”, “eating behavior” and “physical activity”. Terms like “alexithymia”, “depression”, “stress”, “negative emotions”, and “rumination” were omitted. The methodological quality of the evidence was assessed with a patented rubric. After applying the analysis criteria, 35 articles were obtained, reporting theexistence of reciprocal associations and interactions between ER and at least one of the three behaviors associated with BEB were analyzed. It is concluded that, despite the importance of these behaviors in the vital maintenance of people and the clear impact that emotional regulation has on them, their research has not been sufficient, and more empirical studies in this regard in Latin America are needed.

Apparent and partial digestible energy values for α-amylase (EC 3. 2. 1. 1)-resistant, retrograde starches, isolated from cooked maize and pea starches (RMS and RPS respectively), were determined in male Wistar rats (about 180 g) during a 28–29 d balance period with ten animals per treatment. The starches were provided as supplements (100 g/kg diet) to a semi-synthetic basal diet (B), and their effects on the apparent digestibilities of nitrogen and fat, and on gains of live weight, fat and lean tissue were examined. Diet B alone was the control; sucrose (Su) and Solka-floc cellulose (SFC) were also examined for reference. Apparent digestibilities for Su, SFC, RMS and RPS were 1.0, 0.16, 0.98 and 0.89 respectively. Whereas the apparent digestibilities of gross energy, N and fat in the diet were unaffected by supplementation with Su, each was decreased by supplementation with SFC, RMS and RPS. Partial digestible energy values calculated from the intakes and faecal losses of energy in the basal and supplemented diets were 15, 12.4 and 0.8 kJ/g for RMS, RPS and SFC respectively. These values were smaller than corresponding apparent digestible energy values calculated from the apparent digestibility of the supplement and its gross energy value. Only the Su and starch supplements increased the intake of apparent digestible energy and the gain of live weight. Both starches and Su increased total energy (and fat) deposition to almost similar extents. It is concluded that the resistant starches contribute significant dietary energy, enhance growth and elevate fat deposition to extents almost similar to Su.

Thyroid hormones and beta-blockers both affect energy balance and the heart. The interaction of 3,5,3'-triiodothyronine (T3) and the beta-blocker atenolol on some cardiac and energy balance parameters was therefore investigated. Stock-fed male Wistar rats (approximately 400 g) received 5 micrograms (expt 1) or 1.5 micrograms (expt 2) T3.100 g body wt-1.day-1 for 3 wk, with or without atenolol. In expt 3, rats were overfed with a "cafeteria" diet before and during the experiment and otherwise treated as in experiment 2. Compared with stock-fed (expt 1 and 2) or overfed (expt 3) controls, T3 caused an increase in food intake in experiments 1 and 2 but not in experiment 3. There was a large loss of body fat in all experiments, disproportionately greater than the body weight loss. Protein loss was significant only in experiment 1 and negligible in cafeteria rats. Heart rate and weight were increased, although heart composition remained unchanged. Atenolol, in a dose that abolished T3-induced tachycardia, did not modify any of the other T3 effects investigated, including the hypertrophy of the heart. These results indicate that T3-induced tachycardia can be abolished by concomitant treatment with a beta-blocker without altering parameters connected with energy balance, whereas protein loss caused by T3 can be attenuated by lowering the dose of T3 used and can be further blunted by dietary manipulation (cafeteria overfeeding).

Male Wistar rats with intact or lesioned central nucleus of amygdala (CeA) were kept at rest or subjected to a treadmill running program for 21 consecutive days. Food intake and body weight were monitored throughout the exercise training program. At the end of the program, rats were killed and their carcasses processed for analysis of the contents in energy, fat, and protein. Exercise and CeA lesions induced opposite effects on energy balance; exercise delayed gains in body energy and fat, whereas CeA lesions promoted them. Total energy intake was lower in exercised rats than in sedentary ones over the 12 and 24 h that followed exercise. Food intake was higher in lesioned rats than in intact animals over the second half of the 12-h period that followed exercise. There was no interaction effect of exercise and CeA lesions on energy balance and intake and on body composition. Plasma levels of adrenocorticotropin hormone and corticosterone were higher in exercised rats than in sedentary ones, but there was no difference between lesioned and intact rats. This study, as well as confirming the effect of exercise on energy balance, indicates that CeA lesions may promote energy deposition in rats. Above all the present results provide evidence that CeA does not represent a necessary neuroanatomic structure in the effect of exercise on energy balance.

The effects of the glucocorticoid receptor antagonist, RU-38486 (RU-486), and the mineralocorticoid receptor (MR) antagonist, RU-28318, on energy balance were investigated in a 2 [surgery: ovariectomy (OVX) and sham operation] x 3 (corticosteroid antagonist: placebo, RU-28318, RU-486) experimental design. Rats were treated for 28 days. Food intake and body weight were monitored throughout the treatment period. At the end of the treatment, rats were killed and their carcasses were analyzed for energy and nitrogen contents. Energy content was determined by adiabatic bomb calorimetry, whereas nitrogen was determined in 250-to 300-mg samples of dehydrated carcasses, with the use of the Kjeldahl procedure. The energy as protein was subtracted from total carcass energy to determine energy as fat. The gains in energy, fat, and protein were calculated by subtracting the values obtained at the end of the treatment period from initial values estimated from the body weights measured at the beginning of the experiment. A significant interaction effect of surgery and corticosteroid antagonist was observed on body energy gain, energetic efficiency, and fat gain. Whereas body energy gain, energetic efficiency, and fat gain were larger in OVX rats than in sham-operated animals treated with either placebo or RU-486, they were comparable in OVX and sham-operated rats treated with RU-28318. Surgery, but not corticosteroid antagonist, had a significant effect on digestible energy intake, energy expenditure, and protein gain. All these variables were higher in OVX rats than in sham-operated animals. Surgery also affected corticosterone levels and adrenal weight. Both of these variables were lower in OVX rats than in sham-operated animals. By demonstrating the ability of RU-28318 to attenuate the effects of OVX on energy balance, the present study provides evidence that MR occupation by corticosteroids facilitates the OVX-induced changes in energy balance.

Abstract The objective of the study was to evaluate the potential of Fourier transform infrared spectroscopy (FTIR) analysis of milk samples to predict body energy status and related traits (energy balance (EB), dry matter intake (DMI) and efficient energy intake (EEI)) in lactating dairy cows. The data included 2371 milk samples from 63 Norwegian Red dairy cows collected during the first 105 days in milk (DIM). To predict the body energy status traits, calibration models were developed using Partial Least Squares Regression (PLSR). Calibration models were established using split-sample (leave-one cow-out) cross-validation approach and validated using an external test set. The PLSR method was implemented using just the FTIR spectra or using the FTIR together with milk yield (MY) or concentrate intake (CONCTR) as predictors of traits. Analyses were conducted for the entire first 105 DIM and separately for the two lactation periods: 5 ≤ DIM ≤ 55 and 55 < DIM ≤ 105. To test the models, an external validation using an independent test set was performed. Predictions depending on the parity (1st, 2nd and 3rd-to 6th parities) in early lactation were also investigated. Accuracy of prediction (r) for both cross-validation and external test set was defined as the correlation between the predicted and observed values for body energy status traits. Analyzing FTIR in combination with MY by PLSR, resulted in relatively high r-values to estimate EB (r = 0.63), DMI (r = 0.83), EEI (r = 0.84) using an external validation. Only moderate correlations between FTIR spectra and traits like EB, EEI and dry matter intake (DMI) have so far been published. Our hypothesis was that improvements in the FTIR predictions of EB, EEI and DMI can be obtained by (1) stratification into different stages of lactations and different parities, or (2) by adding additional information on milking and feeding traits. Stratification of the lactation stages improved predictions compared with the analyses including all data 5 ≤ DIM ≤105. The accuracy was improved if additional data (MY or CONCTR) were included in the prediction model. Furthermore, stratification into parity groups, improved the predictions of body energy status. Our results show that FTIR spectral data combined with MY or CONCTR can be used to obtain improved estimation of body energy status compared to only using the FTIR spectra in Norwegian Red dairy cattle. The best prediction results were achieved using FTIR spectra together with MY for early lactation. The results obtained in the study suggest that the modeling approach used in this paper can be considered as a viable method for predicting an individual cow's energy status.
