Nevertheless, its progress is believed to be influenced by modifiable factors, one of the most important being dietary intake. Like many other systems within the human body, detection of nutrients (defined as nutrition sensing), their metabolism, and the body's response to nutrients may change with ageing. There is compelling evidence to suggest that nutrition sensing mechanisms can become dysregulated in certain ageing adults, which can lead to increased morbidity and mortality. However, there is still much to unravel in nutrition sensing and its impact on ageing on multiple levels from molecular signalling to the food environment. We hypothesise that nutrition sensing mechanisms play an important role in the ageing process. To this end, we formed the Ageing and Nutrition Sensing Network to bring together leading multi-disciplinary researchers and early career researchers with expertise across ageing, cell biology, nutrition, epidemiology, and policy. The network aims to address the priority area of health span and quality of life in older age. As a consortium, we defined nutrition sensing and identified five key challenges to be addressed to advance the field of nutrition sensing and ageing. This resulted in the development of four main projects, each one embracing multidisciplinary working and investigating nutrition sensing and ageing from different perspectives.

Although weight loss was an initial motivator for all, participants motivated by health benefits found TRE easier and achieved better weight loss results than those overly focused on losing weight. Participants who achieved moderate weight loss faced TRE challenges due to inconsistent routines and motivations, often switching to 'traditional dieting' during follow-up. Participants who achieved low or no weight loss struggled with irregular routines, low social support, guilt when exceeding the eating window and viewing weight loss as an all-or-nothing goal of TRE, making it unmaintainable.

This briefing paper describes dietary and lifestyle recommendations for women during the preconceptional period and throughout pregnancy, identifying specific factors that can be modified to improve health outcomes for both mother and child. It considers key areas such as nutrient intakes, supplementation, food safety and weight management, and highlights how dietary choices can help reduce the risk of common pregnancy-related conditions. Despite widespread recognition of the importance of a healthy, balanced diet, many women in the UK fall short of recommended intakes for important nutrients, including iron, folate, iodine and vitamin D. These shortfalls are particularly evident among nutritionally vulnerable groups, such as teenagers, women from lower-income households and those experiencing food insecurity; such groups may face barriers to accessing healthy foods and adhering to supplementation guidance. An increasing interest in plant-based diets presents an opportunity to consider a range of dietary patterns that support both maternal health and environmental sustainability. However, such shifts must be carefully managed to ensure adequate intake of nutrients commonly found in animal products, such as vitamin B12, iron, iodine, calcium and long-chain fatty acids. Rates of overweight and obesity among women of childbearing age remain high, reflecting trends in the general population and contributing to growing concern about maternal obesity. Maintaining a healthy weight before and during pregnancy plays a key role in supporting maternal and fetal wellbeing. Both insufficient and excessive weight gain are associated with elevated risks of complications. Excessive weight gain during pregnancy is associated with an increased risk of developing gestational diabetes, hypertensive disorders such as pre-eclampsia, preterm birth and a greater likelihood of long-term obesity in both mother and child. Supporting women to achieve and maintain a healthy weight in the periconceptional period and throughout pregnancy is therefore a public health priority. The antenatal period presents a unique window of opportunity to promote healthier and more sustainable eating patterns, as women are often highly motivated to improve their health and are in more regular contact with healthcare professionals at this time. Yet, research indicates that many women are unaware of dietary recommendations or receive inconsistent advice. To fully harness this opportunity, healthcare providers must be equipped with culturally appropriate, accessible and evidence-based resources to support perinatal conversations around diet, supplementation, physical activity and body weight. Providing appropriate support during the periconceptional and early pregnancy period is essential to addressing health inequalities, improving long-term","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144576716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
