Over the past three decades, the CSIRO has conducted extensive research to understand diet and lifestyle strategies that optimise weight management, health and wellbeing for everyday Australians. Based on this research, scientists have found that a daily protein intake higher than the current recommendations suggest can benefit many people - namely, people who are trying to lose weight; those who need to gain muscle mass; older people who want to stay physically strong and active as they age; and those following a strictly plant-based diet. CSIRO Protein Plus applies the exciting emerging science behind the potential additional benefits that can be achieved by evenly distributing protein across the day. This includes incorporating protein-rich foods at regular meals, with an emphasis on greater protein intake at breakfast as part of a healthy eating plan. This dietary approach, when combined with resistance exercise training, potentially further enhances the effects of a higher-protein diet by promoting even greater appetite (and weight) control and improvements in body composition. These effects can benefit many individuals across the entire adult lifespan. CSIRO Protein Plus is for anyone wanting an evidence-based strategy for achieving weight loss or general weight management, and for people wanting to improve their lifestyle for healthy ageing.
