Summary

This trial will investigate the efficacy of low-carb diets to reduce knee OA pain, with an emphasis on racial differences and interactions with biopsychosocial factors. #OA #RacialDisparities #PainRelief #LCD

Who is the study for?
This trial is for English-speaking adults aged 40-75 with knee osteoarthritis, who self-identify as either Non-Hispanic Black or White, have a BMI of 25-40, eat more than 100g of carbs daily, and experience pain most days. Excluded are those on opioids or certain other meds, with recent weight change, major surgery like knee replacement, severe diseases affecting heart/lungs/digestion/metabolism, extreme exercisers or dieters.
What is being tested?
The study tests if a low-carbohydrate diet can reduce pain and improve quality of life in people with knee OA compared to the standard USDA diet. It will also look at how race might affect these outcomes by focusing on differences between Non-Hispanic Blacks and Whites.
What are the potential side effects?
While not explicitly stated in the provided information, potential side effects from dietary changes may include digestive discomforts such as constipation or diarrhea due to shifts in fiber intake; fatigue during initial adjustment periods; and possible nutrient deficiencies if not properly managed.
