“…On the contrary, in G1, the absence of a factor that decreases the BG levels, cholesterol, low-density lipoproteins, and triglycerides in the blood during lactation maintained active metabolic mechanisms that cause lactational hypophagia (Paspala et al, 2012) and its negative effects on voluntary feed intake (Rigón et al, 2008). The fact that the increase in dFI −1 of sows in G2 was not lineal during the 3 weeks of lactation (Fig.…”

The effect of spineless cactus intake (Opuntia ficus-indica) on blood glucose (BG) levels in lactating sows and its impact on daily and total feed intake (dFI−1 and TFI, respectively), body weight loss (BWL), and weaning-estrus interval length (WEI) were evaluated. Thirty-four hybrid (Yorkshire × Landrace × Pietrain) sows in lactation phase were used. Sows were divided into two groups: G1 (n = 17) where they received commercial feed and G2 (n = 17) provided with commercial feed plus an average of 2.0 ± 0.5 kg spineless cactus, based on a sow’s body weight. The variables evaluated were BG, dFI−1, TFI, BWL, and WEI. Statistical analysis was performed by using a fixed and mixed model methodology, under a repeated measurements experiment. Group effects were found on all analyzed variables (P < 0.05). The BG was lower in G2 (55.2 and 64.5 mg/dL pre- and post-prandial, respectively), compared to that in G1 (70.9 and 80.1 mg/dL pre- and post-prandial, respectively) (P < 0.05). G2 showed better performance than G1 for dFI−1, BWL, and WEI (P < 0.05) whose averages were 5.5 ± 1.8 kg, 7.4 ± 4.5%, and 5.3 ± 1.2 days, respectively. Averages for these variables in G1 were 4.7 ± 1.5 kg, 16.8 ± 4.6%, and 6.1 ± 1.6 days, respectively. Intake of spineless cactus reduced BG levels in lactating sows, generating greater dFI−1, lower BWL at the end of lactation, and a lower WEI.

“…Ghrelin is produced predominantly by the cells of the gastric fundus, the majority of which is removed during this procedure. Ghrelin stimulates appetite, increases gastric motility and secretion, increases growth hormone secretion and reduces fat utilization [ 10 – 12 ]. Short-term studies have confirmed the safety and effectiveness of this restrictive procedure; however, limited long-term data (> 5 years) are available so far [ 9 , 13 – 15 ].…”

IntroductionSurgical intervention in obesity is today the most effective treatment method in high level obesity management. Bariatric interventions not only ensure body weight reduction, but may influence dietary habits.AimTo assess changes in adipose hormones and dietary habits in obese patients after sleeve gastrectomy.Material and methodsThe study set comprised 37 subjects (29 females and 8 males) 24 to 68 years old with body mass index 43.0 ±4.9 kg/m2. Pre-operative examination included baseline measurements of body composition. Dietary habits and intake frequency were monitored by a questionnaire method. Follow-up examinations were carried out in a scope identical to the pre-operative examination, 6 and 12 months after surgery, respectively.ResultsThe average patient weight loss 12 months after surgery was 31.7 kg. Excess weight loss was 55.2 ±20.6%. Patients reported reduced appetite (p < 0.001), increasingly regular food intake (p < 0.001), intake of more meal portions per day (p = 0.003) and a decrease in consuming the largest portions during the afternoon and evening (p = 0.030). Plasma levels of fasting glucose, leptin and ghrelin significantly decreased (p = 0.006; p = 0.0.043); in contrast, the level of adiponectin significantly increased (p < 0.001).ConclusionsSleeve gastrectomy and follow-up nutritional therapy resulted in a significant body weight reduction within 1 year after surgery. An improvement of certain dietary habits in patients was registered. At 12 months after surgery, there were no statistically significant differences in decreases in ghrelin and leptin concentrations between patients without changed appetite and those reporting decreased appetite.

“…While food intake refers to 'what we eat', eating behavior refers to 'how we eat'. Food intake is a biological phenomenon that intends to maintain the energy balance of the body, eating behavior is an environmental phenomenon affecting the dietary preferences and food induced hedonic effect 1,2 . Energy intake is affected by various factors and characteristics of the food environment ( Fig.…”

Regulation of Food Intake : A Complex Process

<p>Researchers have created a wealth of knowledge about the mechanisms that regulate food intake, appetite and therefore weight control. The control of appetite is a complex mechanism and involves the coordination of inputs from both physiological and environmental sources. Early theoretical approaches were based on the idea that the control mechanism was dedicated exclusively to signals from glucose metabolism, amino acids or proteins, or adipose tissue. However, a complex system of biologic and environmental factors regulates our appetite. The brain integrates chemical and nervous signals to control hunger and satiety. These controls include sensory and gastrointestinal signals, neurotransmitters and neuropeptides. This review paper summarizes the existing plethora of the highly convoluted process of appetite regulation and food intake.</p>
