Objetivos: Examinar a prevalência da sub e supernotificação da ingestão energética em adolescentes e seus fatores associados. Métodos: Estudo transversal com 96 adolescentes na pós-puberdade (47 com peso normal e 49 obesos), com idade média de 16,6±1,3 anos. Peso e altura foram medidos e o índice de massa corporal foi calculado. A composição corporal foi avaliada através de absorciometria por raios X de dupla energia. A ingestão de alimentos foi avaliada por meio de um registro alimentar de 3 dias. Realizou-se uma avaliação bioquímica (níveis séricos de colesterol total, LDL, HDL, glicose plasmática e insulina). Os subnotificadores relataram uma ingestão energética < 1,35 x taxa metabólica basal (TMB), enquanto os supernotificadores relataram uma ingestão energética > 2,4 x TMB. Resultados: Notificação imprecisa (sub ou supernotificação) da ingestão energética foi identificada em 65,6 por cento dos adolescentes (64,6 e 1 por cento de sub e supernotificação, respectivamente). Os adolescentes obesos apresentaram 5.0 vezes mais chances de subnotificar a ingestão energética (IC95 por cento 2,0-12,7) do que os participantes com peso normal. Os subnotificadores apresentaram taxas mais altas de ingestão insuficiente de carboidratos (19...

O consumo de alimentos é frequentemente avaliado em estudos sobre a etiologia de doenças crônicas não-transmissíveis. A maioria desses estudos nutricionais utiliza métodos que dependem de auto-relato e são susceptíveis a potenciais erros. Um desses principais vieses é o sub-relato da ingestão energética, o qual consiste no relato de energia implausivelmente inferior às quantidades mínimas necessárias à manutenção do peso corporal do indivíduo. Objetivos: Identificar a prevalência e os fatores associados ao sub-relato e analisar os padrões dietéticos de indivíduos sub-relatores e não sub-relatores da ingestão energética. Métodos: Foram utilizados dados do estudo transversal de base populacional ISA - Capital 2008, de indivíduos com 20 anos ou mais, de ambos os sexos. A ingestão energética foi avaliada pela média de dois recordatórios de 24 horas coletados em dias não consecutivos. O gasto energético total foi calculado por equação preditiva, considerando sub-relatores indivíduos com ingestão energética inferior a 1 ou 2 desvios-padrão (DP) da razão ingestão energética/gasto energético total predito. A análise de regressão múltipla foi utilizada para identificar os fatores associados à subnotificação e a análise fatorial por componentes principais foi utilizada para identificar os padrões alimentares. Resultados: A prevalência de sub-relatores da ingestão energética utilizando o ponto de corte de 2 DP foi de 15...

Introdução. O consumo de açúcares aumentou consideravelmente nas últimas décadas, bem como a incidência e a prevalência da obesidade, gerando a elaboração de recomendações para moderá-lo. Os açúcares contribuem para a palatabilidade dos alimentos, podendo também aumentar sua densidade energética (DE), outro fator de risco para obesidade. Uma alternativa seria a substituição por adoçantes não calóricos, que também aumentam a palatabilidade dos alimentos, porém são isentos calorias. No entanto, ainda não existe consenso a respeito das implicações desta substituição principalmente na redução da ingestão energética e do peso corporal. Objetivo. Identificar a DE da dieta, a ingestão energética total e de macronutrientes, segundo consumo de adoçantes e/ou alimentos processados com adoçantes por adultos e idosos. Métodos. Estudo transversal, no qual foram coletados dados de sexo; idade; peso e estatura, para cálculo do IMC; consumo de adoçantes, por questionário adaptado e pelo recordatório de 24 horas, foram calculadas as médias de DE, de ingestão energética total e de macronutrientes. Para verificar associação entre variáveis independentes (idade, sexo, IMC, uso de adoçantes não calóricos) com a dependente "classificação da DE foi realizada regressão logística...

O objetivo do estudo foi descrever e comparar dois métodos de avaliação de consumo calórico e uma medida de gasto energético aplicados em adolescentes de uma coorte de nascimentos. Em uma subamostra da coorte de 1993 de Pelotas, Rio Grande do Sul, Brasil, acompanhada em 2006-2007, informações sobre consumo calórico foram obtidas através de questionário de frequência alimentar (QFA) e três recordatórios de 24 horas (R24h), enquanto gasto energético foi avaliado por acelerômetro. Gráficos de Bland & Altman foram usados na comparação dos métodos. A diferença média entre QFA e R24h foi 592 ± 929cal/dia. Ao comparar com gasto energético, o consumo foi superestimado se medido pelo QFA (357 ± 968cal/dia) e subestimado pelo R24h (-278 ± 714cal/dia). Apesar da grande diferença no consumo, menores diferenças foram observadas quando os dois métodos foram comparados ao gasto energético.; The study aims to describe and compare two methods of energy intake assessment and one measure of energy expenditure applied in adolescents from a birth cohort. In a sub-sample of the 1993 Pelotas (Brazil) birth cohort, followed up in 2006-7, information on intake was obtained through a food-frequency questionnaire (FFQ) and three 24-hour-recalls (24hR)...

The study aims to describe and compare two methods of energy intake assessment and one measure of energy expenditure applied in adolescents from a birth cohort. In a sub-sample of the 1993 Pelotas (Brazil) birth cohort, followed up in 2006-7, information on intake was obtained through a food-frequency questionnaire (FFQ) and three 24-hour-recalls (24hR), while energy expenditure was assessed using an accelerometer. Bland & Altman plots were used in the analyses in order to compare the methods. The mean difference between FFQ and 24hR was 592 ± 929cal/day. Compared to energy expenditure, intake was overestimated when measured by FFQ (357 ± 968cal/day) and underestimated by 24hR (-278 ± 714cal/day). In spite of the great differences between energy intake obtained using the two methods, lower differences were observed when these methods were compared to expenditure.

BACKGROUND: Gastric distension reduces food intake, and antral, rather than proximal, gastric distension may be the dominant mechanism in the induction of appetite-related sensations. Healthy aging is associated with reduced appetite. OBJECTIVE: We examined the effects of different energy preloads on appetite, plasma cholecystokinin, antral area, and subsequent energy intake in healthy older and young subjects. DESIGN: On 3 separate days, 12 young and 12 older subjects consumed 400 mL of a drink containing either 0 kcal (water), 250 kcal, or 750 kcal 70 min before a buffet-style meal. RESULTS: Hunger was less in the older than in the young subjects (P < 0.001). Both nutrient preloads reduced hunger and increased fullness more than did water (P < 0.02), and older subjects were more full than were the young (P < 0.05). Antral area was greater after the nutrient preloads than after water (P = 0.001) and greater in the older than in the young subjects (P = 0.005). In both groups, food intake was suppressed in an energy-dependent manner (P = 0.008). Plasma cholecystokinin was greater in the older than in the young subjects (P = 0.003). Immediately before the meal, hunger (r = -0.59) and energy intake (r = -0.90) were inversely related and fullness (r = 0.66) was directly related to antral area (all: P < 0.001). Antral area...

The presence of fat in the small intestine slows gastric emptying, stimulates the release of many gastrointestinal hormones, and suppresses appetite and energy intake as a result of the digestion of fats into free fatty acids; the effects of free fatty acids are, in turn, dependent on their chain length. Given these effects of fat, it is paradoxical that high dietary fat intakes have been linked to increased energy intake and body weight and are considered to play a significant role in the pathogenesis of obesity. However, increasing evidence indicates that a chronic increase in dietary fat is associated with an attenuation of the feedback signals arising from the small intestine induced by fat, with a consequent relative acceleration of gastric emptying, modulation of gastrointestinal hormone secretion, and attenuation of the suppression of energy intake. This review addresses the gastrointestinal factors involved in the regulation of appetite and energy intake, with a particular focus on 1) the gastrointestinal mechanisms triggered by small intestinal fat that modulate energy intake, 2) the potential role of a high dietary fat intake in the development of obesity, and 3) implications for the prevention and management of obesity.; Tanya J Little...

This thesis presents studies relating to effects of different macronutrients, predominantly fat and carbohydrate, on gastrointestinal motility, hormone release/suppression, appetite and energy intake in healthy subjects, and on symptom generation in patients with functional dyspepsia. The three broad areas that have been investigated in these studies are: (i) the effect of load, and duration, of small intestinal nutrient exposure on gastric motility, gastrointestinal hormone release/suppression, appetite and energy intake in healthy subjects, (ii) the dietary factors that may contribute to symptom generation in patients with functional dyspepsia, through analysis of diet diaries and acute nutrient challenges, and (iii) the effects of the herbal medication, Iberogast®, on gastric motility in healthy subjects. The ingestion of nutrients, triggers a number of gastrointestinal responses, including the modulation of antropyloroduodenal motility, gastrointestinal hormone release/suppression, and the suppression of appetite and energy intake, resulting in a slowing of gastric emptying to an average rate of 1 - 3 kcal/min, which is required for efficient nutrient digestion and absorption. Additionally, the rate at which glucose enters the small intestine influences postprandial glycaemia and incretin responses. These responses have been demonstrated in animals to be dependent on the length...

BACKGROUND: The regulation of gastrointestinal function and energy intake by fatty acids depends on their chain length. Animal studies suggest that lauric acid (C12) may have more potent suppressive effects on energy intake than does oleic acid (C18). OBJECTIVE: We compared the effects of equicaloric loads of C12 and C18 on antropyloroduodenal (APD) motility, plasma concentrations of cholecystokinin (CCK) and peptide YY (PYY), appetite, and energy intake. DESIGN: Thirteen healthy men (aged 20-46 y) were studied on 3 occasions in double-blind, randomized fashion. APD pressure waves, plasma hormones, and appetite perceptions were measured during 60-min intraduodenal infusions of 1) C12, 2) C18, or 3) 0.9% saline as control (rate: 4 mL/min; energy load for C12 and C18: 0.4 kcal/min); between 60 and 90 min, the subjects consumed a meal. Energy intake at a buffet meal was quantified. RESULTS: C12 and C18 both reduced antral (P < 0.001) and duodenal (P < 0.01) pressure waves and stimulated isolated pyloric pressure waves (P < 0.01) and plasma CCK (P < 0.001), with no differences between them. Although C12 and C18 both increased basal pyloric pressure (P < 0.05), C12 had a greater effect than did C18 (P < 0.01). In contrast, although both C12 and C18 increased plasma PYY (P < 0.001)...

Gastric emptying, as well as intragastric meal distribution, and gastrointestinal hormones, including cholecystokinin (CCK), play an important role in appetite regulation. The evaluation of gastrointestinal factors regulating food intake is commonly performed in healthy, lean, young male participants. It has, however, been suggested that there is a marked interindividual variability in the effects of nutrient ‘preloads’ on energy intake in this group. Whether there is significant intraindividual variation in acute energy intake after a nutrient preload, and, if so, how this relates to day-to-day differences in gastric emptying and gastrointestinal hormone release, is unclear. The purpose of the present paper is to evaluate the hypothesis that energy intake after a nutrient preload would be reproducible and associated with reproducible patterns of gastric emptying, intragastric distribution and gastrointestinal hormone release. Fifteen healthy men (age 25 (sem 5) years) consumed a glucose preload (50 g glucose in 300 ml water; 815 kJ) on three occasions. Gastric emptying and intragastric meal distribution (using three-dimensional ultrasound), blood glucose, plasma insulin and CCK concentrations and appetite perceptions were evaluated over 90 min...

Background: The interaction of nutrients with the small intestine modulates gastropyloroduodenal motility, stimulates the release of gut hormones, and suppresses appetite and energy intake. Objective: We evaluated which, if any, of these variables are independent determinants of acute energy intake in healthy, lean men. Design: We pooled data from 8 published studies that involved a total of 67 healthy, lean men in whom antropyloroduodenal pressures, gastrointestinal hormones, and perceptions were measured during intraduodenal nutrient or intravenous hormone infusions. In all of the studies, the energy intake at a buffet lunch was quantified immediately after the infusions. To select specific motor, hormone, or perception variables for inclusion in a multivariable mixed-effects model for determination of independent predictors of energy intake, we assessed all variables for collinearity and determined within-subject correlations between energy intake and these variables by using bivariate analyses adjusted for repeated measures. Results: Although correlations were shown between energy intake and antropyloroduodenal pressures, plasma hormone concentrations, and gastrointestinal perceptions, only the peak number of isolated pyloric-pressure waves...

BACKGROUND: Intraduodenal fat and carbohydrate modulate antropyloroduodenal motility and hormone release and suppress appetite and energy intake in a load-dependent manner. Protein also suppresses energy intake, but its effects on these gastrointestinal factors and their role in the appetite-suppressive effects of protein remain unclear. OBJECTIVE: We aimed to characterize the effects of different intraduodenal protein loads on antropyloroduodenal pressures, gastrointestinal hormone release, glucose and insulin concentrations, appetite perceptions, and energy intake. DESIGN: Sixteen lean, healthy men were studied on 4 occasions in a randomized, double-blind fashion. Antropyloroduodenal pressures, plasma glucagon-like peptide 1 (GLP-1), cholecystokinin, peptide YY, ghrelin, blood glucose, serum insulin, and appetite were measured during 60-min, 4-mL/min intraduodenal infusions of protein at 0.5, 1.5, or 3 kcal/min or saline (control). Energy intakes at a buffet lunch consumed immediately after the infusion were quantified. RESULTS: Increases in the load of protein resulted in greater suppression of antral motility, greater stimulation of basal and isolated pyloric pressures and plasma cholecystokinin and GLP-1 concentrations, and greater suppression of energy intake. However...

While protein is regarded as the most satiating macronutrient, many studies have employed test meals that had very high and unsustainable protein contents. Furthermore, the comparative responses between lean and obese subjects and the relationships between energy intake suppression and gut hormone release remain unclear. We evaluated the acute effects of meals with modest variations in 1) fat, protein, and carbohydrate content and 2) protein load on gastrointestinal hormones, appetite, and subsequent energy intake in lean and obese subjects. Sixteen lean and sixteen obese men were studied on four occasions. Following a standardized breakfast, they received for lunch: 1) high-fat (HF), 2) high-protein (HP), 3) high-carbohydrate/low-protein (HC/LP), or 4) adequate-protein (AP) isocaloric test meals. Hunger, fullness, and gut hormones were measured throughout, and at t = 180 min energy intake at a buffet meal was quantified. In lean subjects, hunger was less and fullness greater following HF, HP, and AP compared with HC/LP meals, and energy intake was less following HF and HP compared with HC meals (P < 0.05). In the obese subjects, hunger was less following HP compared with HF, HC/LP, and AP meals, and energy intake was less following HP and AP compared with HF and HC meals (P < 0.05). There were no major differences in hormone responses to the meals among subject groups...

The research presented in this thesis focuses on the complex and interrelated oral and gastrointestinal mechanisms involved in the regulation of appetite and energy intake in lean and obese individuals. The three broad areas of research that have been investigated in the thesis include: i) the gastrointestinal motor and hormonal functions involved in the regulation of energy intake in healthy individuals; ii) the effects of oral and intraduodenal nutrients on gastrointestinal motility and hormone release, appetite and energy intake in obese compared with lean individuals; and iii) the effects of acute and prolonged energy restriction on gastrointestinal function, appetite and energy intake. Following ingestion of a meal, the interaction of nutrients with receptors in the small intestinal lumen modulates gastro-pyloroduodenal motility, stimulates the release of gastrointestinal hormones, and suppresses appetite and energy intake. It appears that modulation of gastrointestinal functions, that is, gastrointestinal motility and hormone release/suppression, mediate the regulation of appetite and acute energy intake in humans, at least in part. Changes in motility and hormone secretion occur concurrently with changes in appetite; however...

BACKGROUND: A 4-d 70% energy restriction enhances gastrointestinal sensitivity to nutrients associated with enhanced energy-intake suppression by lipid. To our knowledge, it is unknown whether these changes occur with 30% energy restriction and are sustained in the longer term. OBJECTIVES: We hypothesized that 1) a 4-d 30% energy restriction would enhance effects of intraduodenal lipid on gastrointestinal motility, gut hormones, appetite, and energy intake in lean and obese men and 2) a 12-wk energy restriction associated with weight loss would diminish effects of acute energy restriction on responses to lipid in in obese men. DESIGN: Twelve obese males were studied before (day 0) and after 4 d (day 5), 4 wk (week 4), and 12 wk (week 12), and 12 lean males were studied before and after 4 d of consumption of a 30% energy–restricted diet. On each study day, antropyloroduodenal pressures, gut hormones, and appetite during a 120-min (2.86-kcal/min) intraduodenal lipid infusion and energy intake at a buffet lunch were measured. RESULTS: On day 5, fasting cholecystokinin was less, and ghrelin was higher, in lean (P < 0.05) but not obese men, and lipid-stimulated cholecystokinin and peptide YY and the desire to eat were greater in both groups (P < 0.05)...

BACKGROUND: Protein-rich supplements are used widely for the prevention and management of undernutrition in older people. The use of protein supplements in older people could, however, be counterproductive by reducing appetite and overall energy intake. OBJECTIVE: The objective was to determine whether aging influences the effects of protein loads, administered directly into the small intestine, on energy intake, antropyloroduodenal motility, and appetite. DESIGN: Intraduodenal infusions (240 mL, 60 min) of saline (0 kcal, control) and protein (hydrolyzed whey) loads of 30, 90, and 180 kcal were followed by an ad libitum buffet meal in 10 young (19-29 y) and 10 healthy older (68-81 y) men. Suppression of energy intake (kcal) at the meal by protein infusion compared with control was calculated. RESULTS: In young subjects, a dose-responsive suppression (±SEM) of energy intake was found at the buffet meal by protein (suppression at 30 kcal: 7 ± 8%, P = 0.189; 90 kcal: 17 ± 8%, P = 0.054; 180 kcal: 33 ± 7%, P = 0.002), whereas suppression was observed only after the 180-kcal load in older subjects (30 kcal: 7 ± 4% increase, P = 0.126; 90 kcal: 6 ± 7% increase, P = 0.291; 180 kcal: 17 ± 6% suppression, P = 0.016). Suppression of energy intake by protein was less in older than in young subjects (P < 0.005). In young subjects...

Energy intake, and the foods and beverages contributing to that, are considered key to understanding the high obesity prevalence worldwide. The relative contributions of energy intake and expenditure to the obesity epidemic, however, remain poorly defined in Spain. The purpose of this study was to contribute to updating data of dietary energy intake and its main sources from food and beverages, according to gender and age. These data were derived from the ANIBES (???Anthropometry, Intake, and Energy Balance in Spain???) study, a cross-sectional study of a nationally representative sample of the Spanish population (from 9???75 years old). A three-day dietary record, collected by means of a tablet device, was used to obtain information about food and beverage consumption and leftovers. The final sample comprised 2009 individuals (1,013 men, 996 women). The observed mean dietary energy intake was 7.6 ?? 2.11 MJ/day (8.2 ?? 2.22 MJ/day for men and 6.9 ?? 1.79 MJ/day for women). The highest intakes were observed among adolescents aged 13???17 years (8.4 MJ/day), followed by children 9???12 years (8.2 ?? 1.80 MJ/day), adults aged 18???64 (7.6 ?? 2.14 MJ/day) and older adults aged 65???75 years (6.8 ?? 1.88 MJ/day).

Protein-rich supplements are used widely for the management of malnutrition in young and older people. Protein is the most satiating of the macronutrients in young. It is not known how the effects of oral protein ingestion on energy intake, appetite and gastric emptying are modified by age. The aim of the study was to determine the suppression of energy intake by protein compared with control and underlying gastric-emptying and appetite responses of oral whey protein drinks in 8 healthy older men (69-80y) compared to 8 young male controls (18-34y). Subjects were studied on 3 occasions to determine the effects of protein loads of 30g/120kcal and 70g/280kcal compared to a flavored water control-drink (0g whey-protein) on energy intake (ad libitum buffet-meal), and gastric emptying (3D-ultrasonography) and appetite (0-180min) in a randomized, double-blind, cross-over design. Energy intake was suppressed by the protein compared with control (P=0.034). Suppression of energy intake by protein was less in older men (1±5%) than young controls (15±2%; P=0.008). Cumulative energy intake (meal+drink) during the protein days compared with the control day increased more in older (18±6%) men than young (1±3%) controls (P=0.008). Gastric emptying of all three drinks was slower in older men (50% gastric-emptying time: 68±5min) than young controls (36±5min; P=0.007). Appetite decreased in young...

OBJECTIVE: To compare dietary intake of women supplemented with multiple micronutrients (MM) or iron only during pregnancy. MATERIALS AND METHODS: Design: Randomized, double-blind, controlled community-based trial. Setting: One semi-urban community in Central Mexico. Subjects: Pregnant women identified before week 13 of pregnancy, willing to provide informed consent. Interventions: Women were randomly assigned to receive daily supplementation with MM or iron only from recruitment until delivery. Supplements were delivered to the participants' home and compliance observed daily. Dietary intake was assessed by repeat 24-hr recall. Data were analyzed using non-parametric tests and multiple regression analysis to determine the impact of MM supplementation on dietary intake of energy and select micronutrients. RESULTS: During the third trimester, women in the MM group consumed more energy and iron from dietary sources than women in the iron only group. After adjustment for differences between the groups at baseline, women in the MM group consumed 111.3 kcal/day more (p<0.05) energy. The difference in iron intake was not significant after adjusting for the increase in energy intake. CONCLUSIONS: Women consuming MM supplements during pregnancy increased energy intake from dietary sources without a concurrent increase in micronutrient density. Future studies should include measures of appetite and physical activity during pregnancy to determine the implications of additional energy intake for weight gain and retention.

OBJECTIVE: To compare dietary intake of women supplemented with multiple micronutrients (MM) or iron only during pregnancy. MATERIALS AND METHODS: Design: Randomized, double-blind, controlled community-based trial. Setting: One semi-urban community in Central Mexico. Subjects: Pregnant women identified before week 13 of pregnancy, willing to provide informed consent. Interventions: Women were randomly assigned to receive daily supplementation with MM or iron only from recruitment until delivery. Supplements were delivered to the participants' home and compliance observed daily. Dietary intake was assessed by repeat 24-hr recall. Data were analyzed using non-parametric tests and multiple regression analysis to determine the impact of MM supplementation on dietary intake of energy and select micronutrients. RESULTS: During the third trimester, women in the MM group consumed more energy and iron from dietary sources than women in the iron only group. After adjustment for differences between the groups at baseline, women in the MM group consumed 111.3 kcal/day more (p<0.05) energy. The difference in iron intake was not significant after adjusting for the increase in energy intake. CONCLUSIONS: Women consuming MM supplements during pregnancy increased energy intake from dietary sources without a concurrent increase in micronutrient density. Future studies should include measures of appetite and physical activity during pregnancy to determine the implications of additional energy intake for weight gain and retention.
