Twenty-seven percent of US adults are actively working to lose
weight, per Gallup’s November 2024 national poll of 1,001 adults
— the closest available proxy for dissatisfaction with eating patterns
that might motivate adopting a meals-only structure. That figure is
the inaction-side proxy shown above. It falls short of a direct regret
measure: the meals-only pattern is the minority position in the US,
so the question “do you regret not snacking?” is structurally rare,
and most adults who restrict to defined meals do so deliberately as
a weight-management or blood-sugar strategy rather than as a
regret-driven reversal of a prior snacking habit.
On the other side, 25% of US consumers set a food or nutrition-
related New Year’s resolution in 2024, per Purdue’s Consumer Food
Insights survey of 1,200 US adults — up six percentage points from
2023, with “the majority” planning to limit salty snacks, sugary
foods, regular soft drinks and alcohol. That 25% spans many dietary
goals, not snacking, so the action-side proxy is the snacking-specific
slice: roughly 13-18% of all US adults if “the majority” means about
half to two-thirds of those with resolutions, which we set at ~15%.
Even that ~15% is prospective intent to cut snacks, not retrospective
regret about a snacking habit. The structural
backdrop: USDA NHANES 2017-March 2020 data show 95% of US adults
snack on a given day, 78% snack multiple times, and among consumers
snacks contribute 24% of daily energy and 43% of added sugars. The
two figures come from different instruments (Purdue resolution
intent vs Gallup active weight-management) and measure different
constructs (prospective resolution vs current effort), so any
cross-side comparison is approximate.
The meal-frequency question is genuinely contested in the nutrition
literature. Bellisle’s 2014 Physiology & Behavior review concludes
that snacking neither clearly causes obesity nor clearly prevents
it, that eating frequency does not independently predict body weight
when total energy intake is controlled, and that the same eating
pattern can have different effects depending on food quality and
context. That weakens the case for either side carrying strong
regret: most US adults snack, most US adults who snack are not
measurably worse off for it when energy intake is matched, and the
few who reverse to a meals-only pattern do not have unambiguous
evidence that their previous behavior caused them measurable harm.
The ~12-point gap between the ~15% snacking-resolution share and the
27% active weight-management share is a difference between two weak,
non-comparable proxy instruments, not a measured difference in
regret. Readers should treat both figures as proxies for different
constructs and not read the delta as a precise regret comparison.

[1]News-Medical / coverage of Purdue Consumer Food Insights Jan 2024 — Increasing New Year's resolutions for healthier eating, Purdue report finds
Fonte de referência
25% of US consumers had a food/nutrition-related New Year's resolution in 2024 (up 6 pp from 2023); the majority plan to increase fruits, vegetables and water while limiting salty snacks, sugary foods, regular soft drinks and alcohol; 46% anticipate cravings as an obstacle
Trecho
“"25% of consumers responded 'yes' when asked if they had any food or nutrition-related New Year's resolutions, up 6 percentage points from the response to the same question last year... the survey-based report out of Purdue University's Center for Food Demand Analysis and Sustainability...included 1,200 consumers across the U.S."

Purdue Center for Food Demand Analysis and Sustainability, Consumer Food Insights, Volume 3 Issue 1, January 2024, N=1,200 US consumers. The 25% headline is the share of US consumers with ANY food/nutrition-related New Year's resolution, covering many dietary goals (more fruit/veg/water, less salty snacks, sugary foods, soft drinks, alcohol) — it is NOT a snacking-specific figure and NOT a regret measure. Because the report says \"the majority\" of those resolutions target the salty-snacks/sugary-foods/soft-drinks/alcohol basket (not snacking alone), the snacking-targeted share is roughly 0.25 x ~50-70% = 13-18% of all US adults. We therefore set the action-side proxy to the midpoint, ~15% (regret_rate 0.15), and label it explicitly as prospective resolution intent to cut snacks/sugary foods, not retrospective regret about snacking. The earlier 25% figure fused the all-resolutions headline with a snacking claim and overstated the snacking-targeted signal; this has been corrected.

USDA Dietary Data Brief No. 53, based on NHANES 2017-March 2020 nationally representative dietary recall data. Establishes the prevalence baseline: 95% of US adults snack at least once on a given day; 78% snack multiple times; snacks contribute 24% of daily energy and 43% of added sugars on average. Used here on the action side as the govt_report context: snacking is the normal modern US eating pattern, not a deviation. This is NOT the regret-rate figure; that is from Purdue Jan 2024 (see above). The NHANES data establishes that the question \"do you regret snacking?\" applies to nearly all US adults if at all, and that the dietary stakes (43% of added sugars from snacks among consumers) are concrete.

Cálculo
Piernas & Popkin (J Nutr 2010) established the long-run shift: US adult snacking went from a minority behavior (71% on any given day in 1977-78) to near-universal (97% by 2003-06), with the share of daily energy from snacks rising from 18% to 24%. Used on the action side as the peer-reviewed historical baseline for the prevalence claim above. This is NOT the action-side regret-rate figure; that is the snacking-specific share (~15%) derived from Purdue's January 2024 resolution survey (see above). Snacking-related regret has not been directly surveyed in the US, so the action side relies on a prospective resolution-intent proxy, not a retrospective regret measure.

Cálculo
Gallup national poll, N=1,001 US adults, fielded November 6-20, 2024, margin of error ±4 percentage points. Used here as the inaction-side proxy: 27% of US adults are actively pursuing weight management, a state that implies current dissatisfaction with some aspect of current eating behavior including the absence of structural snacking discipline. This is NOT a direct regret measure about the meals-only pattern; in fact, the meals-only pattern is the minority position (95% of US adults snack daily per NHANES), so the question \"do you regret not snacking?\" is structurally rare. The 27% captures the directional signal: a substantial minority of US adults are actively dissatisfied enough with their current diet to do something about it, and \"cut the snacks\" is one of the most common dietary-change targets in popular guidance.

[2]Physiology & Behavior / France Bellisle — Meals and snacking, diet quality and energy balance
Verificado
Revisado por pares
Snacking may contribute to excess energy intake and weight gain via context, frequency and food quality; in some reports snacking facilitates energy-intake adjustment to needs, in others (especially obese populations) it contributes energy but little nutrition
Trecho
“"Snacking may contribute to excess energy intake and weight gain through different ways, for example: context/environment of eating, frequency of consumption and quality of food choices. In many reports, snacking appears to facilitate the adjustment of energy intake to needs, and to contribute carbohydrates, rather than fats, to the diet. By contrast, snacking often appears to contribute much energy but little nutrition in the diet of other consumers, particularly obese children and adults."

Cálculo
Bellisle (Physiology & Behavior 2014) is the canonical peer- reviewed review framing the meal-frequency literature. The critical finding: eating frequency does not independently predict body weight when total energy intake is controlled. Used here on the inaction side as the literature basis for the observation that the case for a meals-only pattern is genuinely contested — snacking neither clearly causes obesity nor clearly prevents it, and the same eating pattern can have different effects depending on food quality and context. This is NOT the regret rate; that is from Gallup 2024. Bellisle's review provides the scientific context that weakens the case for the inaction side carrying strong regret: most US adults snack, most US adults who snack are not measurably worse off for it when energy intake is matched, and the few who reverse to a meals-only pattern do not have unambiguous evidence that their previous behavior was harmful.

Ressalvas
Nenhum dos lados mede o arrependimento diretamente, e nenhuma pesquisa publicada nos EUA pergunta de forma direta "você se arrepende de petiscar entre as refeições?" ou "você se arrepende de não petiscar?". A questão da frequência das refeições é genuinamente contestada na literatura de nutrição (Bellisle 2014, Physiol Behav): a frequência alimentar não prediz de forma independente o peso corporal quando a ingestão total de energia é controlada. A pesquisa Purdue Consumer Food Insights de janeiro de 2024 constatou que 25% dos consumidores dos EUA têm ALGUMA resolução de Ano Novo relacionada a alimentação/nutrição; esses 25% abrangem muitas metas dietéticas, não apenas os petiscos. Como "a maioria" dessas resoluções tem como alvo a categoria de petiscos salgados/alimentos açucarados/refrigerantes/álcool, a parcela específica de petiscos é de aproximadamente 13-18% de todos os adultos dos EUA, portanto definimos o proxy do lado da ação no ponto médio, ~15%. (Uma versão anterior usava os 25% completos, o que fundia o número de destaque de todas as resoluções com uma afirmação sobre petiscos e superestimava o sinal da ação.) Mesmo em 15%, isto é intenção prospectiva de resolução, não arrependimento retrospectivo quanto a petiscar. Os 27% do lado da inação são a parcela da Gallup de novembro de 2024 de adultos dos EUA que estão ativamente tentando perder peso — um sinal relacionado, mas indireto, e o padrão de fazer apenas refeições é, em si, a posição minoritária nos EUA (95% dos adultos dos EUA petiscam diariamente, segundo o USDA NHANES 2017-março de 2020), de modo que a pergunta "você se arrepende de não petiscar?" é estruturalmente rara. Usamos o número de 27% de esforço ativo de perda de peso como o proxy adjacente ao arrependimento disponível mais próximo. Os dois números vêm de instrumentos e populações diferentes (pesquisa de intenção de resolução da Purdue versus enquete de controle ativo de peso da Gallup) e medem constructos diferentes (resolução prospectiva versus esforço atual), portanto qualquer comparação entre os lados é aproximada e não deve ser lida como uma diferença de arrependimento precisa. O regret_delta de ~12 pontos reflete dois instrumentos proxy não comparáveis, e não uma diferença medida de arrependimento. Subjacente à questão do arrependimento está a causalidade contestada: os dados do NHANES mostram que os petiscos contribuem com 24% da energia diária e 43% dos açúcares adicionados entre os consumidores, o que estabelece o padrão de petiscar como um dos principais contribuintes para a ingestão de calorias pobres em nutrientes, mas a revisão de Bellisle argumenta que a dimensão da frequência das refeições é em grande parte subordinada à ingestão total de energia e à qualidade dos alimentos.
