Effects of Extra Virgin Olive Oil (EVOO) and the Traditional Brazilian Diet on Sarcopenia in Severe Obesity: A Randomized Clinical Trial.
Study Goal
The researchers aimed to evaluate the effectiveness of extra virgin olive oil (EVOO) and a healthy traditional Brazilian diet (DieTBra) on improving sarcopenia indicators (including walking speed) and reducing total body fat in severely obese adults.
Results Summary
The study found that DieTBra contributed to improvements in walking speed and handgrip strength, along with reductions in total body fat. The combination of DieTBra and EVOO showed significant benefits in these outcomes.

BACKGROUND: Nutritional interventions may have positive effects on sarcopenia and body composition. OBJECTIVE: to evaluate the effectiveness of extra virgin olive oil (EVOO) consumption and a healthy traditional Brazilian diet (DieTBra) on improving sarcopenia indicators and reducing total body fat in severe obesity. METHODS: A randomized controlled trial registered at ClinicalTrials.gov (NCT02463435) conducted with 111 severely obese participants randomized into three treatment groups-(1) EVOO (52 mL/day), (2) DieTBra, (3) DieTBra + EVOO (52 mL/day)-for 12 weeks. Body composition was assessed by dual-energy X-ray absorptiometry and sarcopenia by walking speed and handgrip strength. RESULTS: Significant reductions in total body fat ( CONCLUSIONS: DieTBra contributes to improvements in handgrip strength, walking speed, and total body fat in severely obese adults. The major study was registered at ClinicalTrials.gov (NCT02463435).
