Effectiveness of High Protein Diets in Promoting Weight Loss in Overweight and Obese Subjects.

February 16, 2007 updated by: University of Wollongong

A Diet Higher in Animal-Based Protein is More Effective in Promoting Weight Loss in Overweight and Obese Individuals Than Other Protein Based Diets.

Several studies have reported greater weight loss when following high meat-protein diets but limited studies have studied high plant-based protein diets. Thus we aim to investigate the effect of high protein diets in weight management and also to investigate the superior protein source in achieving this effect. In addition, we aim to develop dietary intervention strategies that are realistic and sustainable.
