What do individuals with morbid obesity report as a usual dietary intake? A narrative review of available evidence.

Background: In several developed countries, as obesity prevalence doubles it has quadrupled for morbid obesity (BMI ≥ 40 kgm). As more individuals with morbid obesity present for weight loss treatment there is a greater need to understand their dietary habits. No reviews were found in the literature, therefore this systematic review aims to identify and describe the existing evidence on the usual dietary intake of individuals with morbid obesity including those from a general population and those seeking treatment such as weight loss surgery.
