Headline vs Study
- Headline: Researchers Reveal How Nearby Food Stores Affect Patients After Weight-Loss Surgery.
- Press Release: Nearby Food Stores Affect Results After Weight-Loss Surgery.
- Study: Presence of Food Stores Within 5 or 10 Minutes Walking Distance Were Significantly Associated with Weight Loss After Surgery in Some Subgroups of Patients. Shopping at or Consuming Foods from Stores Not Measured. Causation Not Established.
- Additional Publication on Same Study: Presence of 'Low' Food Selection Diversity Food Stores Within 5 or 10 Minutes Walk Significantly Associated with Less Weight Loss After Surgery; Pooled 'Medium/High' Diversity Was Not Significant. Shopping at or Consuming Foods from Stores Not Measured. Causation Not Established.
- Critique: Food Stores “Drive” Bariatric Surgery Outcomes?
Contrary or Null Findings
- "Despite widespread discussion of weight gain in association with the COVID-19 Shutdown, study data showed no evidence of adverse effects of Shutdown on body weight, BMI, HbA1C, or blood glucose in a large sample of adults with T2DM."
- RCT: "Supplementation with 6,000 IU vitamin D daily during 12 weeks in children and adolescents with obesity and hypovitaminosis D [had no discernable] positive effects on weight loss, insulin resistance, lipid patterns, or blood pressure were observed."
- "Surprisingly, we find that variation in the slope of individual scaling relationships primarily results from variation in nutritionally-induced plasticity of body size, not leg or wing size."
- "Unexpectedly, our results show that the SFL [Sustainability Facts Label] increased the likelihood of organic purchases."
- RCT: "Abundance and Scarcity conditions do not affect average switching directly, but they influence the behavior of high-income subjects and cause the income effect to vanish by reverting the consumption behavior of high-income subjects to the behavior of low-income subjects."
