Conditions overweight, obesity, sedentary lifestlye
Treatment weight management program

End date December 2015
Trial size 80 participants
Trial identifier NCT02012426, KRISTAL No., LDS-2013-SLW


The aim of the current study is to demonstrate that a commercial weight management diet (i.e. low energy density) influences satiation, hunger and satiety and leads to lower energy intake during ad-libitum meals and over a full day. We further seek to demonstrate the sustainability of this effect following 12- week weight loss on the weight management program.

- We hypothesise that formulated (low energy) meals will lead to decreased hunger, greater fullness and reduced desire to eat compared to standard meals.

- We hypothesise that the commercial weight management program will lead to greater weight loss compared to control program.

- We hypothesise that formulated meals (high consumer acceptance) will improve hedonic control over eating (lower wanting for high fat food)

- We hypothesise that the commercial weight management program will improve hedonic control over eating (reduced experience food cravings)
