Abstract

Dietary restraint theoretically increases risk for binge eating, but prospective and experimental studies have produced contradictory findings, apparently because dietary restraint scales do not identify individuals who are reducing caloric intake. Yet, experimentally manipulated caloric deprivation increases responsivity of brain regions implicated in attention and reward to food images, which may contribute to binge eating. We tested whether self-imposed acute and longer-term caloric restriction increases responsivity of attention and reward regions to images, anticipated receipt, and receipt of palatable food using functional magnetic resonance imaging among female and male adolescents (Study 1 n=34; Study 2 n=51/81). Duration of acute caloric deprivation correlated positively with activation in regions implicated in attention, reward, and motivation in response to images, anticipated receipt, and receipt of palatable food (e.g., anterior cingulate cortex, orbitofrontal cortex, putamen, and precentral gyrus respectively). Youth in a longer-term negative energy balance likewise showed greater activation in attention (anterior cingulate cortex, ventral medial prefrontal cortex), visual processing (superior visual cortex), reward (caudate) and memory (hippocampus) regions in response to receipt and anticipated receipt of palatable food relative to those in neutral or positive energy balance. Results confirm that self-imposed caloric deprivation increases responsivity of attention, reward, and motivation regions to food, which may explain why caloric deprivation weight loss diets typically do not produce lasting weight loss.

TL;DR

In two fMRI studies of adolescents, longer self-imposed caloric deprivation and a 2-week negative energy balance were associated with greater responsivity of attention, reward, and motivation brain regions to palatable food images, anticipated milkshake receipt, and milkshake receipt. The authors argue this may help explain why caloric-deprivation weight-loss diets often do not produce lasting weight loss.

Key findings

  • Study 1 (N = 34 female adolescents; mean deprivation 7.8 ± 4.6 hours, range 1–16): duration of caloric deprivation correlated positively with left OFC activation for appetizing > unappetizing food pictures and right precentral gyrus activation for appetizing > water pictures; no significant effects emerged for reverse contrasts or quadratic relations.
  • Study 2 acute deprivation (n = 51; mean 6.9 ± 3.7 hours, range 3–22.5): hours since last caloric intake correlated positively with activation during milkshake cue > tasteless cue in regions including MTG, precentral gyrus, medial SFG, lingual gyrus, dlPFC, dorsal ACC, MFG, IOG, vlPFC, parahippocampal gyrus, putamen, cerebellum, thalamus, and MOG; for milkshake receipt > tasteless receipt, it correlated positively with left mid insula.
  • Study 2 longer-term energy balance: the negative energy balance group (≥1 kg loss; n = 27; mean −1.5 ± 0.5 kg) showed greater activation than the positive energy balance group (n = 23; mean +1.7 ± 0.9 kg) in left precuneus, left mPFC, and right ventral ACC for anticipated receipt, and in left caudate and right precentral gyrus for receipt; versus the energy stable group (n = 31; mean −0.01 ± 0.08 kg), it showed greater activation in left cuneus, left dlPFC, and left PCC for anticipated receipt, and bilateral caudate, right hippocampus, left MOG, and left fusiform gyrus for receipt.
  • Dutch Restrained Eating Scale scores were not significantly related to hours of food deprivation in Study 1 (p = 0.98; r = 0.004) or Study 2 (p = 0.46; r = 0.10), and did not differ across energy balance groups (p = 0.92).

Methods

  • Two fMRI studies in adolescents. Study 1 included 34 healthy female adolescents (M age = 15.5 ± 0.9, BMI = 24.6 ± 5.6). Study 2 included 162 adolescent males and females (M age = 15.3 ± 1.07, BMI = 20.8 ± 1.90), but analyses used 51 participants with data on pre-scan caloric deprivation and 81 participants meeting weight-change criteria.
  • Study 1 used a food-picture paradigm: participants rated 103 food pictures, then viewed their 40 most appetizing, 40 least appetizing, and 40 water pictures; contrasts were appetizing > unappetizing and appetizing > water, regressed on hours since last dietary intake.
  • Study 2 used a milkshake receipt/anticipation paradigm with chocolate milkshake versus calorie-free tasteless solution; contrasts were milkshake receipt > tasteless receipt and milkshake cue > tasteless cue, regressed on hours since last caloric intake and compared across negative, stable, and positive energy balance groups based on 2-week weight change (lost ≥1 kg, remained within 0.1 kg, gained ≥1 kg). Imaging used SPM8 with whole-brain cluster-level correction (p < 0.001, k ≥ 11, corrected p < 0.05).

Limitations

  • The paper states: there was no way to confirm that the negative energy balance group consumed fewer calories than needed on the actual scan day; only one palatable food was tested and it was a beverage, so generalization to solid foods is cautious; participants were adolescents, so results may not generalize to adults; and sample sizes, though larger than many imaging studies, were still moderate and may have limited power and generalizability.
  • Evident from the text: the acute-deprivation analyses in Study 2 used only 51 of 162 participants because deprivation data were not collected for all; Study 1 included only females while Study 2 included both sexes; and the acute-deprivation findings are correlational, based on self-reported hours since last intake rather than experimentally manipulated deprivation.

    Interpretationreasoning

    Weight loss diets that involve replacement of unhealthy energy dense foods with healthy low energy density foods should be more effective than diets that involve long periods of caloric deprivation.

    “Most critically, findings imply that weight loss diets that involve the replacement of unhealthy energy dense foods with healthy low energy density foods should be more effective than diets that involve long periods of caloric deprivation.”

    If people attempt to lose weight by abstaining from food intake for long durations, it will increase the reward value of food, which may lead to poor food choices when the individual eventually does eat.

    “Our results imply that if people attempt to lose weight by abstaining from food intake for long durations of time, it will have the effect of increasing the reward value of food, which may lead to poor food choices when the individual eventually does eat.”

  • The paper relies on this without support.

    Weight change over the 2-week period is a valid index of negative, neutral, or positive energy balance.

    “To assess the impact of longer-term energy balance we used weight change over the 2-week period during which the scan occurred to group participants into three a priori groups”
    “This allowed us to contrast the neural response of individuals who were in an objectively measured negative energy balance to those who were in an energy stable or positive energy balance state when the scan took place.”
  • The paper relies on this without support.

    Number of hours since last caloric intake is a valid measure of acute caloric deprivation.

    “participants reported the number of hours since their last dietary intake (to the nearest quarter hour)”
    “duration of caloric deprivation”
  • The paper relies on this without support.

    BOLD response in attention and reward regions reflects responsivity or reward value to food.

    “BOLD response was contrasted during receipt of milkshake versus tasteless solution”
    “activation in regions implicated in attention, reward, and motivation”

    Caloric deprivation weight loss diets typically do not produce lasting weight loss.

    “which may explain why caloric deprivation weight loss diets typically do not produce lasting weight loss.”
  • The paper relies on this without support.

    Participants' self-reported duration of elective acute caloric deprivation accurately reflects their actual caloric deprivation.

    “participants reporting a longer duration of elective acute caloric deprivation”
    “Hours since last caloric intake and negative energy balance status showed no correlation with scores on the Dutch Restrained Eating Scale”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-09.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-09.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
