Ultra-Processed Diets Cause Excess Calorie Intake and Weight Gain: An Inpatient Randomized Controlled Trial of Ad Libitum Food Intake
Open accessAbstract
Summary We investigated whether ultra-processed foods affect energy intake in 20 weight-stable adults, aged (mean±SE) 31.2±1.6 y and BMI=27±1.5 kg/m2. Subjects were admitted to the NIH Clinical Center and randomized to receive either ultra-processed or unprocessed diets for 2 weeks immediately followed by the alternate diet for 2 weeks. Meals were designed to be matched for presented calories, energy density, macronutrients, sugar, sodium, and fiber. Subjects were instructed to consume as much or as little as desired. Energy intake was greater during the ultra-processed diet (508±106 kcal/d; p=0.0001), with increased consumption of carbohydrate (280±54 kcal/d; p<0.0001) and fat (230±53 kcal/d; p=0.0004) but not protein (−2±12 kcal/d; p=0.85). Weight changes were highly correlated with energy intake (r=0.8, p<0.0001) with participants gaining 0.9±0.3 kg (p=0.009) during the ultra-processed diet and losing 0.9±0.3 kg (p=0.007) during the unprocessed diet. Limiting consumption of ultra-processed foods may be an effective strategy for obesity prevention and treatment.

“we calculated that protein leverage could potentially explain at most ~50% of the observed energy intake differences between the diets assuming perfect leverage”
§ Ultra-processed diets cause excess calorie intake and weight gain: An inpatient randomized controlled trial of ad libitum food intake > Results and Discussion > Food Intake
What the sources say
- Partly supportedcites Hall, 2019 sourceExperimental — accuracy not yet measured
The indexed passage labeled Abstract (page not provided) defines perfect protein leverage and models its effect on energy intake. It does not report that leverage explains at most ~50% of observed energy-intake differences between diets; its quantitative estimate instead concerns about two-thirds of the rise in mean adult body weight in the US.

“suggests that the protein leverage hypothesis could partially explain the increase in energy intake with the ultra-processed diet”
§ Ultra-processed diets cause excess calorie intake and weight gain: An inpatient randomized controlled trial of ad libitum food intake > Results and Discussion > Food Intake
What the sources say
- Supportedcites Martinez Steele et al., 2018 sourceExperimental — accuracy not yet measured
The paper’s conclusions propose that the lower protein density of ultra-processed foods may help account for their association with excess energy intake. Its protein leverage hypothesis section reports that energy intake rose as dietary protein density fell across increasing levels of ultra-processed food consumption. This supports the citing sentence’s tentative explanation, though the source examines dietary associations rather than a controlled ultra-processed diet. (LLM, conf=0.90)

“the ~85% higher energy density of the non-beverage foods in the ultra-processed versus unprocessed diets (Table 1) likely contributed to the observed excess energy intake”

What the sources say
- Not checked — no full text of the sourcecites DellaValle et al., 2005 source
- Supportedcites Rolls, 2009 source
The ‘Energy density and satiation’ section reports that changing food energy density changed ad libitum energy intake even when macronutrient proportions were held constant. This supports the cited inference that higher food energy density likely contributed to greater intake; the ~85% comparison is presented as the citing study’s own Table 1 result. (LLM, conf=0.88)

“However, current dietary assessment methods are insufficient to accurately or precisely measure energy intake outside the laboratory (Schoeller, 1990; Schoeller et al., 2013) and adherence to study diets cannot be guaranteed in free-living subjects.”

The section “Might the reporting error have increased in recent years?” says self-reported energy-intake data have too much systematic error to track energy balance. The Conclusions also call self-reported intake fatally flawed, but identify other validated tools to develop for measuring intake in free-living people. The source therefore supports the claim about self-report methods, not its blanket statement about all current dietary assessment methods. (LLM, conf=0.88)

“After the unprocessed diet, fasting glucose and insulin levels tended to decrease compared to baseline and the homeostasis model assessment of insulin resistance (HOMA-IR) (Matthews et al., 1985) was significantly decreased compared to baseline.”

- Supportedcites Matthews et al., 1985 source
The citation is attached to the name of the homeostasis model assessment of insulin resistance (HOMA-IR), identifying the measure used. The paper’s section “HOMA compared with the hyperglycaemic clamp” reports HOMA estimates of insulin resistance; the diet-related decrease is the citing authors’ own result, not a finding attributed to Matthews et al.

“This sample size calculation was informed by previous studies measuring day to day variability of ad libitum energy intake having a standard deviation of about 500–600 kcal/d (Bray et al., 2008; Edholm et al., 1970; Tarasuk and Beaton, 1992).”

- Partly supportedcites Bray et al., 2008 sourceExperimental — accuracy not yet measured
The Results section (page unavailable) reports substantial day-to-day variation in energy intake, and the Discussion gives an average within-person coefficient of variation of 25%. The paper does not report a standard deviation of 500–600 kcal/d; its mention of 600 kcal describes occasional deviations from a person's average, not the standard deviation. (LLM, conf=0.84)
- Partly supportedcites Edholm et al., 1970 sourceExperimental — accuracy not yet measured
The Results (p. 1097) analyse day-to-day variation in recruits’ energy intake, and the Discussion (Vol. 24) describes the variation as strikingly large. However, the retrieved passages do not report an intake standard deviation of about 500–600 kcal/day; the Dietary survey (p. 1095) describes meals served to recruits rather than explicitly identifying the intake as ad libitum.

The paper relies on this without support.
Before this trial, no causal link between ultra-processed food intake and human obesity had been established, and no randomized controlled trial had tested whether reducing or increasing ultra-processed foods affects health.
“no causal relationship between ultra-processed food consumption and human obesity has yet been established”
“there has never been a randomized controlled trial demonstrating any beneficial effects of reducing ultra-processed foods or deleterious effects of increasing ultra-processed foods in the diet”
The authors state this as an assumption.
The mean of the measured chamber periods was representative of the 24-hour period.
“All chamber measurement periods were >23 hours and we extrapolated the data to represent 24hr periods by assuming that the mean of the measured periods was representative of the 24hr period.”
The authors state this as an assumption.
Within-subject energy intake correlations were zero.
“Using the conservative assumption that within-subject energy intake correlations were zero, over the 14-day diet period each subject was expected to have a mean energy intake with a standard error of about 130–160 kcal/d and the mean energy intake difference between the study diets was therefore estimated to have a standard error of about 190–230 kcal/d.”
The paper relies on this without support.
Adherence to study diets cannot be guaranteed in free-living subjects.
“However, current dietary assessment methods are insufficient to accurately or precisely measure energy intake outside the laboratory (Schoeller, 1990; Schoeller et al., 2013) and adherence to study diets cannot be guaranteed in free-living subjects.”

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.
A language model drew the claims from the paper on 2026-09-28, under version 3 of the claim definition (prompt extract-v3).
A second model labelled each claim on 2026-09-28 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
