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.

    Increasing New Year's resolutions for healthier eating, Purdue report finds
    統計値
    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
    抜粋
    “"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.

    計算過程
    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.

    計算過程
    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.

    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
    抜粋
    “"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." ”

    計算過程
    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.
    独立性
    Independent peer-reviewed academic review with publicly disclosed methodology; Bellisle has published widely on eating frequency, including some industry-funded studies on snacking listed in her overall body of work but the 2014 P&B review is not directly industry-sponsored.

注意事項

いずれの側も後悔を直接測定してはおらず、「間食したことを後悔しているか」あるいは「間食しなかったことを後悔しているか」を正面から尋ねた刊行された米国の調査は存在しない。食事の頻度の問題は栄養学の文献で真に議論のあるところである(Bellisle 2014, Physiol Behav):総エネルギー摂取量を一定にすると、食事の頻度は体重を独立に予測しない。Purdue Consumer Food Insightsの2024年1月調査では、米国の消費者の25%が何らかの食事・栄養に関する新年の抱負を持つことが判明した。その25%は間食ではなく多くの食事目標にまたがる。それらの抱負の「大半」がしょっぱいスナック/砂糖の多い食品/清涼飲料/アルコールの区分を狙っているため、間食に特化した割合は全米国成人のおよそ13〜18%であり、行動側のプロキシをその中点の約15%に設定した。(以前の版では25%全体を用いており、これは全抱負の見出しと間食の主張を混同し、行動シグナルを過大に見積もっていた。)15%であっても、これは間食に関する回顧的な後悔ではなく、将来に向けた抱負の意図である。不作為側の27%は、積極的に減量に取り組む米国成人の割合を示すGallupの2024年11月の数値であり——関連はするが間接的なシグナルである。食事のみのパターンは米国では少数派の立場そのものであるため(USDA NHANES 2017〜2020年3月によれば米国成人の95%が毎日間食する)、「間食しなかったことを後悔しているか」という問いは構造的にまれである。最も入手可能な後悔に近いプロキシとして27%という積極的な減量努力の数値を用いる。2つの数値は異なる手段と母集団(Purdueの抱負意図調査対Gallupの積極的体重管理調査)に由来し、異なる構成概念(将来の抱負対現在の努力)を測っているため、両側の比較はいずれも近似であり、正確な後悔差として読むべきではない。約12ポイントの regret_delta は、測定された後悔の差ではなく、比較できない2つのプロキシ手段を反映している。後悔の問いの根底には議論のある因果関係がある:NHANESのデータは、消費者の間でスナックが1日のエネルギーの24%と添加糖の43%を占めることを示しており、間食パターンが栄養に乏しいカロリー摂取の主要な寄与因子であることを確立するが、Bellisleのレビューは、食事の頻度の次元は総エネルギー摂取量と食品の質に大きく従属すると論じている。
