How sustainable are hypocaloric and balanced diets for weight loss?
Article in Nutrition & metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPromoting healthy diets with low environmental impact is pivotal. The EAT-IT diet aligns with the EAT-Lancet Commission, tailored to Italian food habits. However, a comparison with weight loss diets has not been done. This cross-sectional study compares EAT-IT with historical diets of an urban nutritional care facility.
objectiveTo compare conventional hypocaloric and balanced weight-loss diets with the sustainable EAT-IT diet, investigating their alignment, the influence of BMI and sex on EAT-IT adherence, to optimize the EAT-IT diet for weight management.
methods4032 patients (72% female, median age 49y, BMI 29 kg/m2) received hypocaloric diets based on Mediterranean principles (51% carbohydrates, 31% lipids, 0.9 g/kg body weight protein, 17 g/1000 kcal fiber), following Italian dietary guidelines.
resultsLinear regression revealed lower EAT-IT alignment in males (-2.6%, p < 0.001) and a small BMI effect on food group adherence (0.4%, p = 0.005). Only 44% of prescribed food groups were in line to EAT-IT. Protein sources (fish 13%, red meat 13%) were generally higher than EAT-IT, except for legumes (26%) and nuts (10%) prescribed in lower quantities and frequencies, as well as vegetable oil (12%) and fresh fruits (11%). Complex carbohydrates-rich foods (13% bread, 12% pasta/cereals) and vegetables (21%) were prescribed in higher quantities in hypocaloric diets, being more aligned with the EAT-IT pattern.
conclusionsProtein sources, being less sustainable, pose challenges in hypocaloric diets. Differences in consumption of vegetable foods were found according to sex and BMI, highlighting the struggle to meet EAT-IT sustainability criteria. Reconciliation between sustainable and hypocaloric dietary interventions is crucial.
