The Effect of a Multi-component Weight Management Program on Appetite, Food Preference and Body Weight (SWSS)
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)
