Background. Portion sizes of many foods have increased over time and reducing food portion sizes has been proposed as a public health strategy to reduce obesity. However, the extent to which reducing food portion sizes affects daily energy intake and body weight is unclear. Objective. To systematically review and meta-analyse experimental studies that have examined the effect that serving smaller vs. larger portion sizes has on total daily energy intake. Design. We used systematic review methodology to search identify eligible articles that used an experimental design to manipulate portion size served to human participants and measured energy intake for a minimum of one day. Multi-level meta-analysis was used to used to pool effects of portion size on daily energy intake. Results. Fourteen eligible studies were included and 85 effects were included in the primary meta-analysis. There was a moderate-to-large reduction in daily energy intake when comparing smaller vs. larger portions (SMD = -.709 [95% CI: -.956 to -.461], p < .001, I2 = 80.6%) and evidence of a dose dependent response. Larger reductions to portion size and reducing portion sizes of multiple meals per day both resulted in larger decreases in daily energy intake. There was also evidence of a curvilinear relationship between portion size and daily energy intake, whereby reductions to daily energy intake were markedly smaller when reducing portion size from very large portions. In a subset of studies that measured body weight (n=5), being served smaller portions was associated with less weight gain than larger portions (SMD = .536 ([95% CI: .268 to .803], p < .001, I2 = 47.0%). Conclusions. Smaller food portion sizes substantially decrease daily energy intake and there is evidence that over time this results in lower body weight. Reducing food portion sizes may be an effective population level strategy to reduce obesity.

Although meal replacement can lead to weight reduction, there is uncertainty whether this dietary approach implemented into a lifestyle programme can improve long-term dietary intake. In this subanalysis of the Almased Concept against Overweight and Obesity and Related Health Risk (ACOORH) study (n = 463), participants with metabolic risk factors were randomly assigned to either a meal replacement-based lifestyle intervention group (INT) or a lifestyle intervention control group (CON). This subanalysis relies only on data of participants (n = 119) who returned correctly completed dietary records at baseline, and after 12 and 52 weeks. Both groups were not matched for nutrient composition at baseline. These data were further stratified by sex and also associated with weight change. INT showed a higher increase in protein intake related to the daily energy intake after 12 weeks (+6.37% [4.69; 8.04] vs. +2.48% [0.73; 4.23], p < 0.001) of intervention compared to CON. Fat and carbohydrate intake related to the daily energy intake were more strongly reduced in the INT compared to CON (both p < 0.01). After sex stratification, particularly INT-women increased their total protein intake after 12 (INT: +12.7 g vs. CON: −5.1 g, p = 0.021) and 52 weeks (INT: +5.7 g vs. CON: −16.4 g, p = 0.002) compared to CON. Protein intake was negatively associated with weight change (r = −0.421; p < 0.001) after 12 weeks. The results indicate that a protein-rich dietary strategy with a meal replacement can improve long-term nutritional intake, and was associated with weight loss.

ABSTRACT Objective: To characterize breakfast eating among Brazilian adolescents. Methods: Food intake was estimated based on a 1-day food record of adolescents aged 10-19 years, according to the first National Diet Survey (2008-2009). Breakfast was considered as the first meal of the day eaten between 4 and 11 am. Results: Ninety-three percent of adolescents reported eating breakfast. This meal contributed to 17.7% of the daily energy intake. The most commonly consumed food groups were: coffee and tea, breads, butter/margarine, milk, cakes and cookies, packaged snacks, corn-based dishes, cheese, processed meats, and fruit juice. In the Northern region there was a higher frequency of coffee and tea and roots and tubers intake and lower frequency of milk intake than that in the other regions in the country. In the Northeastern region, the intake of corn and eggs was high; in the Southern region, there was high intake of processed meats and fruits. Adolescents from families in the first income quartile reported higher intake of coffee and tea, packaged snacks, corn, and roots and tubers intake, and lower intake of milk and dairy products. Adolescents from families in the highest income quartile reported higher intake of milk, fruit juice, cheese, and sugar-added beverages. Conclusion: In Brazil, the contribution of breakfast to daily energy intake among adolescents is low. The nutritional quality of breakfast improved with increased income. The three most frequently consumed items were coffee and tea, breads, and butter/margarine.
