This systematic review provides compelling evidence supporting the hypothesis that social norms significantly influence dietary practices, both healthy and unhealthy. By experimentally manipulating information about others’ eating habits, researchers demonstrated that eating norms exert a moderate but measurable impact on food intake and choices. Meta-analyses revealed that high intake norms increased food consumption (Z=3.84; P=0.0001; standardized mean difference 0.41, 95% CI 0.20 to 0.63), while low intake norms reduced it (Z=2.78; P=0.005; standardized mean difference -0.35, 95% CI -0.59 to -0.10).
Additionally, there was consistent evidence that information about food choices influenced participants’ behavior, with norm-based cues about low-energy or high-energy foods significantly increasing the likelihood of individuals selecting similar options. These findings suggest that informational eating norms can be strategically leveraged to encourage healthier eating habits and reduce overconsumption, highlighting their potential for public health interventions.
By shaping norms that promote healthier dietary behaviors, society can foster positive changes that align individual actions with broader health goals, offering a promising avenue for addressing dietary-related health challenges.

In the context of the systematic review, low intake norms and high intake norms refer to social cues or information provided to individuals about the typical eating behavior of others, specifically the quantity of food consumed. These norms influence an individual’s perception of what is socially acceptable or expected in a given situation, thereby affecting their own eating behavior.
Low intake norms: These suggest that others are eating smaller quantities of food or consuming fewer calories. For example, participants might be informed that most people in a similar situation eat small portions or low-calorie meals. This information creates a social expectation to eat less, which often leads individuals to reduce their own food intake to conform to the perceived norm.
High intake norms: These indicate that others are eating larger quantities of food or consuming more calories. For instance, participants might be told that people in similar contexts tend to eat larger portions or high-calorie meals. Such cues can encourage individuals to eat more to align with the social expectation of higher consumption.
These norms are experimentally manipulated in studies by providing participants with fabricated or real information about the eating habits of others, allowing researchers to measure the influence of such social information on participants’ food intake and choices.

A notable study by Lumeng and Hillman examined this effect in children aged 2–6 years. The researchers compared children’s snack consumption in groups of three and groups of nine. Each session was videotaped to assess the number of graham cracker portions consumed, as well as eating rates and meal durations. The findings indicated that children ate more when in larger groups, suggesting that the presence of peers can significantly influence eating behavior.

Mechanisms Behind Social Facilitation of Eating in Children:
Modeling: Children often imitate the eating behaviors of their peers. If peers eat larger quantities, a child may be inclined to do the same, consciously or unconsciously adopting similar eating patterns.
MDPI
Social Interaction: Eating in a group setting can be more enjoyable and may lead to longer meal durations, providing more opportunities to eat. This extended time spent at the table can contribute to increased food intake.
PMC
Peer Influence: The desire to fit in or be accepted by peers can lead children to adjust their eating behaviors to match those around them. This peer influence can play a significant role in shaping eating habits.

salvy et al., 2010
Male and female children consumed less energy from unhealthy snacks when in the presence of their mothers than when in the company of their friends. Conversely, female adolescents consumed less energy from unhealthy snacks and more energy from healthy snacks when they were with their friends than when with their mothers.
Conclusions: Food selection is differentially influenced by the source of social influence and the age and sex of the child. Parents may act as an inhibitory influence on unhealthy eating for younger children. Adolescent girls may try to convey a good impression of healthy eating when eating with same-sex friends, but the eating habits of teenage boys are not as influenced by the social context
lab study, buffet meal- ecological validity?
participants (families) were volunteered- certain type of people may volunteer?
