“…In this study, the effect of the MC3r activation on food intake in animals exposed to an HFD was evaluated. Once the recovery period from the stereotaxic surgery ended, daily food intake (g) and body weight were monitored for 10 days, following the same protocol of a previous study (Díaz-Urbina et al, 2018). On day 16, the pharmacological treatments were administrated in the lateral ventricle and the behavioral test was carried out at the onset of the dark phase.…”

“…Consumption of HFD alters homeostatic processes, such as spontaneous locomotion (Moretto et al, 2017) and circadian clocks that regulate the feeding schedule (Honma et al, 2016; Kohsaka et al, 2007). We have previously reported that consumption of HFD modifies the feeding efficiency, increasing the energy intake per unit of time, stimulating the early feeding cessation (Díaz-Urbina et al, 2018). Furthermore, animals subjected to obesogenic diets display alterations in neural systems controlling hunger, satiety, and food motivation (Carlin et al, 2016; Fordahl, Locke & Jones, 2016; La Fleur et al, 2010; Mercer et al, 2014).…”

The knowledge about the role of MC3 receptors (MC3r) in the regulation of feeding behavior is limited. The present study was conducted to determine whether MC3r mediates the hypophagic effects of the melanocortins under conditions of positive energy balance. Male Wistar rats were fed with a high-fat diet (HFD) for 15 days and on day 16 the animals received an intracerebroventricular injection of the following treatments: Vehicle, D-Trp8-γ-melanocyte-stimulating hormone (MSH; MC3r agonist), SHU9119 (MC3r/MC4r antagonist), or D-Trp8-γ-MSH+SHU9119. Food intake was measured and the behavioral satiety sequence (BSS) analysis was carried out during the first hour of the dark phase. The c-Fos and α-MSH immunoreactivity in the arcuate nucleus (ARC) was evaluated 60 min later the onset of food intake. The results indicated that D-Trp8-γ-MSH decreased the ingestion of the HFD and this effect is associated with the early development of the satiation process Moreover, the D-Trp8-γ-MSH increased the accumulation of the α-MSH in the ARC and the c-Fos activity in the PVN. The antagonist SHU9119 partially prevented the D-Trp8-γ-MSH-induced hypophagia. Moreover, behavioral analysis suggests that central activation of MC3r accelerated the cessation of feeding in conditions of positive energy balance; the possible role of MC4r is discussed. Present data indicate that central stimulation of MC3r prevented the overconsumption of the HFD without affecting the natural satiation process, suggesting a potential use of MC3r for the treatment of eating disorders that are stimulated by hypercaloric diets.

“…According to Licholai et al (2018), high‐fat diets fed ad libitum appear to induce overconsumption in mice; beyond the mechanisms that regulate daily caloric intake. Also, Díaz‐Urbina et al (2017) showed that male rats exposed to the high‐fat diets accumulated more body fat and showed increased feeding behaviour. In most of the previous studies fish oil has been supplemented with normal/high‐fat diets (HFD) in much lower doses (about 5%–10%; Cao et al, 2020) than our study and it has decreased FI.…”

Effects of dietary supplementation of different oils and conjugated linoleic acid on the reproductive and metabolic aspects of male mice

et al. 2022

The present study was carried out to examine first, if diets enriched with 320 g of the base diet with common dietary oils including fish oil, olive oil, hydrogenated sunflower seed (H‐SFS) oil, flaxseed oil and sunflower seed oil (SFS) could induce weight gain and alter reproductive and metabolic characteristics of male mice. Second, whether the addition of conjugated linoleic acid (CLA, 10% of the diet) could ameliorate any negative effects. In this cross‐sectional study, 90 four‐week‐old male NMRI mice were used in two consecutive experiments. A high level of dietary oils negatively affected some reproductive and metabolic characteristics of male mice (p < 0.05), specifically, sunflower seed oil enrichment resulted in higher HDL levels and apoptosis of germinal epithelial cells. An olive oil‐enriched diet caused an increase in plasma triglyceride concentrations and germinal cell apoptosis, as well as a decrease in sperm concentration and perturbed spermatogenesis. When CLA was fed in conjunction with dietary oils it successfully mitigated some of the negative reproductive and metabolic characteristics. We conclude that male reproductive processes are affected by high dietary oils, even before signs of obesity are evident. Inclusion of dietary CLA may provide some benefit to offset negative effects, although further studies are required.

“…Grupo A (n = 33) de azúcares refinados en comparación con el grupo A; esta tendencia se reporta también en el estudio de Escobar y colaboradores, en el que se intervino a una población a la cual se le prescribió una dieta en la que predominaba el consumo de lípidos sobre los HCO en horas de oscuridad, y se reflejó en una ganancia de peso y valores elevados de grasa corporal, similar al consumo y características de la población de este estudio (grupo B) que consume mayor cantidad de lípidos y tiene un %GC mayormente elevado en comparación con el grupo A (17) . En el grupo A, el valor de MMT es superior al del grupo B; con respecto a la masa grasa, es el grupo B el que tiene valores más elevados de esta; Jacubowicz y colaboradores estudiaron una población similar y concluyeron que una dieta basada en un desayuno hipercalórico y una cena hipocalórica pueden resultar benéficos debido a que se verá favorecida la movilización de la grasa almacenada en el tejido adiposo y, por consiguiente, una pérdida de %GC, ya que en horas de oscuridad intervienen distintas hormonas (aumento de leptina y disminución de grelina y resistina), que disminuyen la ingesta de alimentos y controlan la glucemia, por lo que protegen de la aparición de obesidad y de enfermedades crónicas no transmisibles (ECNT) (18,19) .…”

La población universitaria es un grupo vulnerable a cambios radicales en la alimentación que impacta negativamente en la composición corporal. El objetivo del estudio fue comparar la composición corporal de mujeres universitarias de acuerdo con la ingesta de desayunos o cenas hipercalóricas. Material y métodos: estudio transversal analítico, muestra no probabilística. De cada participante se obtuvo peso, estatura, índice de masa corporal (IMC), porcentaje de grasa corporal (%GC) y de masa muscular total (%MMT), así como indicadores dietéticos y de actividad física. Se calculó la media y desviación estándar; además, se realizó la prueba T de Student ANOVA simple, con significancia de p < 0,05 y se calculó el coeficiente de correlación de Spearman. Resultados: 75 universitarias fueron incluidas, con una edad promedio de 18 ± 0,63 años. La ingesta energética promedio del día fue de 1647 ± 385 kcal, con tendencia a los azúcares refinados y a las grasas saturadas. El horario del desayuno fue de 8:30 ± 2,5 horas, almuerzos: 13:30 ± 3,5 horas y cenas: 20:30 ± 3,4 horas. El 85 % de las universitarias con %GC > 28 y %MMT < 34 % consumían el 50 % ± 25 % de la ingesta calórica total por la noche con respecto al desayuno (15 % ± 30 %), y esta diferencia fue significativa (p < 0,05) independientemente del IMC. Conclusiones: en este estudio se observó que las universitarias que consumen desayunos hipercalóricos altos en azúcar y grasa saturada tienen menor GC y mayor masa muscular en comparación con las que consumen cenas con las mismas características y la misma ingesta calórica en el día.
