New analysis from CSIRO has identified a protein gap among women aged 40-55, with survey data showing weight gain is commonly reported by women in this typical menopausal transition age. 

According to an online survey of 1303 female CSIRO Total Wellbeing Diet members, almost eight in 10 reported weight gain during this life stage. 

CSIRO Research Scientist Dr Gilly Hendrie says the findings highlight that eating less isn’t always the answer to midlife weight gain and that many women aged 40-55 may not be eating enough protein at this stage of life.  

She says CSIRO’s separate examination of the 2023-24 National Nutrition and Physical Activity Survey also finds that dietary protein intake for women in the typical menopausal transition age (40-55 years) is around 35g short of optimal dietary protein intake levels (1.2g/kg body weight). One in three survey respondents reported a protein intake at this level.  

“When weight gain occurs during the transition to menopause, it can be tempting to simply eat less,” says Ms Hendrie.

“But making the right food choices and having enough protein becomes especially important at this life stage.

“Adequate dietary protein helps to manage appetite, support muscle mass, strength and overall physical health.”  

Almost 90% of female Total Wellbeing Diet members surveyed also said menopause had some impact on their wellbeing, with one in five describing that impact as significant.

Half of the survey respondents, however, reported that following the Total Wellbeing Diet program helped improve their overall wellbeing. 

“Weight gain and its flow-on effects on wellbeing are commonly experienced by women during menopause, and yet many are unsure what they can actually do to manage their weight during this time,” says Ms Hendrie.  

​​​​​​“The CSIRO Total Wellbeing Diet is designed to make higher-protein eating easier and more practical, helping women close the protein gap without taking a restrictive approach. 

“There’s no one-size-fits-all protein target, which is why understanding your own needs is so important. For women navigating menopause, being more deliberate about dietary protein can be a simple but meaningful step for supporting long-term health.”
