Trends in Weight Loss Attempts and Strategies Among US Adolescents With Overweight or Obesity.
Article in Obesity (Silver Spring, Md.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveThis study assessed national trends in weight loss attempts, clinically meaningful weight loss, and associated strategies among US adolescents with overweight or obesity.
methodsWe analyzed National Health and Nutrition Examination Survey (NHANES) 1999-2023 data for 2708 adolescents aged 16-19 years with overweight or obesity. Weight loss attempts and strategies were self-reported. Clinically meaningful weight loss was defined as ≥ 5% and ≥ 10% body weight reductions or a ≥ 0.2 reduction in body mass index (BMI) z-score over the prior year. Survey-weighted logistic regression assessed temporal trends and associations between strategies and weight loss success.
resultsThe prevalence of weight loss attempts increased from 53.9% in 1999-2000 to 65.7% in 2021-2023 (p for trend < 0.001). Overall, 26.96% achieved a ≥ 5% weight loss and 12.58% achieved a ≥ 10% weight loss; 34.34% achieved a ≥ 0.2 BMI z-score reduction. Exercise and dietary changes were the most reported strategies. Reducing sugar intake (OR, 2.16) and prescription medication use (OR, 2.55) were associated with achieving a ≥ 5% weight loss, and prescription medication use (OR, 3.59) was also associated with achieving a ≥ 10% weight loss. Sugar intake reduction (OR, 1.89) and prescription medication use (OR, 2.73) were associated with achieving a ≥ 0.2 reduction in BMI z-score.
conclusionsWeight loss attempts increased over time, but clinically meaningful weight loss remained uncommon. Improved access to evidence-based, developmentally appropriate interventions is needed.
